     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for managing and visualizing sound reduction. For example, there is a need for an electronic device that provides a user with information about the level of noise the user is exposed to in an easily understandable and convenient manner. In another example, there is a need for an electronic device that effectively alerts the user of the electronic device when the noise level that the user is exposed to exceeds a certain threshold level. In another example, there is a need for an electronic device that effectively alerts the user that the noise level the user is exposed to is being reduced by a sound reduction device and that without the sound reduction device the noise level would be unsafe. In another example, there is a need for an electronic device that provides a user with information about the level of noise reduction the user&#39;s sound reduction device is yielding. Such techniques can reduce the cognitive burden on a user who manages noise exposure levels, sound reduction levels, and sound reduction effects, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS.  1 A- 1 B,  2 ,  3 ,  4 A- 4 B, and  5 A- 5 B,  6 A- 6 I,  7 ,  8 A- 8 H,  9 A- 9 B, and  10    provide a description of exemplary devices for performing the techniques for monitoring noise exposure levels, sound reduction levels, and sound reduction effects.  FIGS.  6 A- 6 I  illustrate exemplary user interfaces for monitoring noise exposure levels and noise-related notifications.  FIG.  7    is a flow diagram illustrating a method of monitoring noise exposure levels using a computer system, in accordance with some embodiments. The user interfaces in  FIGS.  6 A- 6 I  are used to illustrate the processes described below, including the processes in  FIG.  7   .  FIGS.  8 A- 8 H  illustrate exemplary user interfaces for monitoring noise exposure levels with and without a sound reduction effect.  FIGS.  9 A- 9 B  are a flow diagram illustrating a method of monitoring noise exposure levels with and without a sound reduction effect in accordance with some embodiments.  FIG.  10    is a flow diagram illustrating a method of monitoring sound reduction levels in accordance with some embodiments. The user interfaces in  FIGS.  8 A- 8 H  are used to illustrate the processes described below, including the processes in  FIGS.  9 A- 9 B . 
     The processes described below enhance the operability of the devices and make the user-device interfaces more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) through various techniques, including by providing improved visual feedback to the user, reducing the number of inputs needed to perform an operation, providing additional control options without cluttering the user interface with additional displayed controls, performing an operation when a set of conditions has been met without requiring further user input, and/or additional techniques. These techniques also reduce power usage and improve battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In addition, in methods described herein where one or more steps are contingent upon one or more conditions having been met, it should be understood that the described method can be repeated in multiple repetitions so that over the course of the repetitions all of the conditions upon which steps in the method are contingent have been met in different repetitions of the method. For example, if a method requires performing a first step if a condition is satisfied, and a second step if the condition is not satisfied, then a person of ordinary skill would appreciate that the claimed steps are repeated until the condition has been both satisfied and not satisfied, in no particular order. Thus, a method described with one or more steps that are contingent upon one or more conditions having been met could be rewritten as a method that is repeated until each of the conditions described in the method has been met. This, however, is not required of system or computer readable medium claims where the system or computer readable medium contains instructions for performing the contingent operations based on the satisfaction of the corresponding one or more conditions and thus is capable of determining whether the contingency has or has not been satisfied without explicitly repeating steps of a method until all of the conditions upon which steps in the method are contingent have been met. A person having ordinary skill in the art would also understand that, similar to a method with contingent steps, a system or computer readable storage medium can repeat the steps of a method as many times as are needed to ensure that all of the contingent steps have been performed. 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. In some embodiments, these terms are used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. In some embodiments, the first touch and the second touch are two separate references to the same touch. In some embodiments, the first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with a display generation component. The display generation component is configured to provide visual output, such as display via a CRT display, display via an LED display, or display via image projection. In some embodiments, the display generation component is integrated with the computer system. In some embodiments, the display generation component is separate from the computer system. As used herein, “displaying” content includes causing to display the content (e.g., video data rendered or decoded by display controller  156 ) by transmitting, via a wired or wireless connection, data (e.g., image data or video data) to an integrated or external display generation component to visually produce the content. 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG.  1 A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG.  1 A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application-specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs (such as computer programs (e.g., including instructions)) and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals.

     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves.

The one or more buttons (e.g.,  208 ,  FIG.  2   ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG.  2   ). In some embodiments, the electronic device is a computer system that is in communication (e.g., via wireless communication, via wired communication) with one or more input devices. In some embodiments, the one or more input devices include a touch-sensitive surface (e.g., a trackpad, as part of a touch-sensitive display). In some embodiments, the one or more input devices include one or more camera sensors (e.g., one or more optical sensors  164  and/or one or more depth camera sensors  175 ), such as for tracking a user&#39;s gestures (e.g., hand gestures and/or air gestures) as input. In some embodiments, the one or more input devices are integrated with the computer system. In some embodiments, the one or more input devices are separate from the computer system. In some embodiments, an air gesture is a gesture that is detected without the user touching an input element that is part of the device (or independently of an input element that is a part of the device) and is based on detected motion of a portion of the user&#39;s body through the air including motion of the user&#39;s body relative to an absolute reference (e.g., an angle of the user&#39;s arm relative to the ground or a distance of the user&#39;s hand relative to the ground), relative to another portion of the user&#39;s body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user&#39;s body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user&#39;s body). 
     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, California. 
     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output.

Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG.  1 A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more depth camera sensors  175 .  FIG.  1 A  shows a depth camera sensor coupled to depth camera controller  169  in I/O subsystem  106 .

In some embodiments, in conjunction with imaging module  143  (also called a camera module), depth camera sensor  175  is optionally used to determine a depth map of different portions of an image captured by the imaging module  143 . In some embodiments, a depth camera sensor is located on the front of device  100  so that the user&#39;s image with depth information is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display and to capture selfies with depth map data. In some embodiments, the depth camera sensor  175  is located on the back of device, or on the back and the front of the device  100 . In some embodiments, the position of depth camera sensor  175  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a depth camera sensor  175  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface).

In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG.  1 A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety.

Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 .

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs (such as computer programs (e.g., including instructions)), procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG.  1 A ). In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 ( 187 - 1 ), event 2 ( 187 - 2 ), and others. In some embodiments, sub-events in an event (e.g.,  187 - 1  and/or  187 - 2 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event 2 ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definitions  186  include a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG.  2    illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally, executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG.  3    is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG.  1 A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG.  1 A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG.  1 A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG.  1 A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG.  3    is, optionally, stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or computer programs (e.g., sets of instructions or including instructions) need not be implemented as separate software programs (such as computer programs (e.g., including instructions)), procedures, or modules, and thus various subsets of these modules are, optionally, combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that are, optionally, implemented on, for example, portable multifunction device  100 . 
       FIG.  4 A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely exemplary. For example, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
       FIG.  5 A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS.  1 A- 4 B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, published as WIPO Publication No. WO/2013/169849, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, published as WIPO Publication No. WO/2014/105276, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device  500  to be worn by a user. 
       FIG.  5 B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS.  1 A,  1 B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including processes  700 ,  900 , and  1000  ( FIGS.  7 ,  9 A- 9 B, and  10   ). A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG.  5 B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS.  1 A,  3 , and  5 A- 5 B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG.  3    or touch-sensitive surface  451  in  FIG.  4 B ) while the cursor is over a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG.  1 A  or touch screen  112  in  FIG.  4 A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally, based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds optionally includes a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation), rather than being used to determine whether to perform a first operation or a second operation. 
     As used herein, an “installed application” refers to a software application that has been downloaded onto an electronic device (e.g., devices  100 ,  300 , and/or  500 ) and is ready to be launched (e.g., become opened) on the device. In some embodiments, a downloaded application becomes an installed application by way of an installation program that extracts program portions from a downloaded package and integrates the extracted portions with the operating system of the computer system. 
     As used herein, the terms “open application” or “executing application” refer to a software application with retained state information (e.g., as part of device/global internal state  157  and/or application internal state  192 ). An open or executing application is, optionally, any one of the following types of applications:
         an active application, which is currently displayed on a display screen of the device that the application is being used on;   a background application (or background processes), which is not currently displayed, but one or more processes for the application are being processed by one or more processors; and   a suspended or hibernated application, which is not running, but has state information that is stored in memory (volatile and non-volatile, respectively) and that can be used to resume execution of the application.       

     As used herein, the term “closed application” refers to software applications without retained state information (e.g., state information for closed applications is not stored in a memory of the device). Accordingly, closing an application includes stopping and/or removing application processes for the application and removing state information for the application from the memory of the device. Generally, opening a second application while in a first application does not close the first application. When the second application is displayed and the first application ceases to be displayed, the first application becomes a background application. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device  100 , device  300 , or device  500 . 
       FIGS.  6 A- 6 I  illustrate exemplary user interfaces for monitoring sound exposure levels, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG.  7   . 
       FIG.  6 A  illustrates a user who is wearing headphones  600 A, watch  600 B, and using phone  600 C. Headphones  600 A are equipped with a sound reduction feature that can be selectively and/or automatically enabled or disabled. When enabled, the sound reduction feature can reduce the level of noise experienced by the user. For example, while the environmental noise is at a first level, e.g., 80 decibels (due to loud traffic noise), the user experiences only 60 decibels of noise when the feature is enabled. If the user disables the feature in that same environment, he would experience the unmodified 80 decibels of noise. In some embodiments, headphones  600 A also includes one or more microphones for detecting audio commands from the user and/or to measure environmental noise levels. Watch  600 B includes a display  602 A, which in  FIG.  6 A , displays the current time. Watch  600 B also includes rotatable and depressible input mechanism  604  (e.g., rotatable and depressible in relation to a housing or frame of the device), and a microphone  606  for detecting audio commands from the user and/or to measure environmental noise levels. Phone  600 C includes display  602 B, which in  FIG.  6 A , is displaying a home screen. 
     In some embodiments, headphones  600 A includes one or more features of devices  100 ,  300 , and/or  500 . In some embodiments, watch  600 B includes one or more features of devices  100 ,  300 , and/or  500 . In some embodiments, phone  600 C includes one or more features of devices  100 ,  300 , and/or  500 . In some embodiments, headphones  600 A are a wearable electronic device (e.g., earbuds, in-ear listening devices) that include sound generation and sound reduction functions. In some embodiments, headphones  600 A generate an active and/or dynamic sound reduction effect (e.g., the headphones  600 A generate varying levels of sound reduction in response to varying levels of environmental sound). In some embodiments, headphones  600 A generate a constant sound reduction effect (e.g., via mechanical/physical structures of the headphones). In some embodiments, headphones  600 A generate a sound reduction effect when a sound reduction function for headphones  600 A is enabled, and do not generate a sound reduction effect when the sound reduction function is not enabled. 
     As depicted in  FIG.  6 B , home user interface  608 A on watch  600 B includes multiple affordances, each affordance associated with an application stored on watch  600 B. For example, noise affordance  614  launches a noise monitoring application.  FIG.  6 B  depicts watch  600 B receiving user input  612  (e.g., a tap) on noise affordance  614 . In response to receiving user input  612 , device  600  displays user interface  610 A (e.g., an interface associated with the noise application), as depicted in  FIG.  6 C . 
       FIG.  6 C  depicts noise user interface  610 A on watch  600 B while the sound reduction function of headphones  600 A is not enabled and the user is in an environment where the ambient noise level is 90 dB (e.g., without any sound reduction). In  FIG.  6 C , noise user interface  601 A includes indication of time  616  (e.g., indicating a current time of 10:09), noise level indicator  618 , noise meter indicator  620 , and noise status indicator  622 A. Noise level indicator  618  provides a numeric indication (e.g., indicating a current noise level of 90 dB) of a first noise level value (e.g., measured by or determined by watch  600 B based on noise data identified by microphone  606 ) that is experienced by a user of watch  600 B without a sound reduction effect (e.g., noise cancellation sound reduction via headphones  600 A); this level can also be referred to as an environmental and/or unmodified noise level. Noise status indicator  622 A provides a non-numeric indication (e.g., an indication including text and/or graphics) of the first noise level value (e.g., measured by or determined by watch  600 B from noise data derived from microphone  606 ) relative to a first noise level threshold (e.g., a safe noise level threshold, a predetermined  90  dB threshold) and selectable option  624 . Selectable option  624  can be selected by an input to present additional information related to hearing health (e.g., a description of the long term exposure effects of sound levels above a threshold value). In some embodiments, the first noise level threshold is user-configurable. In some embodiments, watch  600 B identifies a noise level based on noise data detected by a sensor (e.g., microphone  606 ) of the watch  600 B (e.g., the first noise level represents a noise level of the physical environment (e.g., environmental noise level) where watch  600 B is located). 
     Noise meter indicator  620  provides a graphical indication of a second noise level (e.g., measured by watch  600 B via microphone  606 ) that corresponds to the noise level indicated by noise level indicator  618 . In some embodiments, the second noise level and the first noise level are the same noise level. In some embodiments, the first noise level and the second noise level are determined based on common noise data sampled at different time periods and/or rates (e.g., 1-second and 0.1-seconds, respectively). Noise meter indicator  620  includes active portion  620 A (e.g., a visually emphasized portion) that varies in size and/or color according to the second noise level. As illustrated by the following figures, the size of active portion  620 A increases as the second noise level increases and the color of the active portion  620 A changes relative to a second noise level threshold. In some embodiments, the size of the active portion  620 A includes one or more visually emphasized units (e.g., bubbles, bars, blocks) that are part of one or more units (e.g., the bubbles, bars, blocks) making up the noise meter indicator  620 . In some embodiments, each emphasized unit in active portion  620 A represents a predetermined number of decibels (e.g., one unit equals 10 dB of noise). In some embodiments, the first noise level threshold and the second noise level threshold are the same noise level (e.g., 86 dB). 
     The noise levels (e.g., values, amplitudes) indicated by the appearance of noise level indicator  618 , noise meter indicator  620 , and noise status indicator  622 A (e.g., as described below), are updated in response to watch  600 B determining one or more noise levels based on received noise data (e.g., the indications update as ambient/environmental noise levels are continuously determined or measured by watch  600 B). In some embodiments, noise levels are measured or detected by a device external to watch  600 B (e.g., device  600 B receives data representing a current noise level from a remote device communicatively coupled with device  600 B). 
     As depicted in  FIG.  6 D , subsequent to a determination that a noise level (e.g., environmental sound level) exceeds a notification sound level threshold (e.g., 80 dB or 86 dB) for a period of time (e.g., a predetermined amount of time, 1-second, or 3-minutes) and that a sound reduction device (e.g., headphones  600 A, earbuds, headphones, etc.) is not being used and/or is not actively producing a sound reduction effect, device  600 B displays noise notification user interface  610 B including noise notification  626 A (e.g., a noise level summary). Noise notification user interface  610 B includes an explanation of what constitutes a loud environment, an explanation of the damage to hearing that can be done from exposure to the loud environment, and suggestions for limiting exposure to the loud environment (e.g., “considering using hearing protection”). Noise notification  626 A includes portions that extend beyond noise notification user interface  610 B displayed on display  602 A and that are accessed in response to device  600 B receiving user inputs at depressible input mechanism  604  (e.g., a scroll input). In response to receiving the inputs, device  600 B displays additional portions of noise notification  626 A of noise notification user interface  610 B as depicted in  FIG.  6 D . 
     As depicted in  FIG.  6 D , noise notification  626 A of noise notification user interface  610 A includes noise application affordance  628  for launching the noise application, mute affordances  630  and  632  for suppressing display of subsequent noise notifications (e.g., display of noise notification user interface  610 B) for a specified time periods (e.g., 1-hour and the remainder of the day). In some embodiments, in response to receiving a user input (e.g., a tap) that is not on affordance  628  ,  630 , or  632 , device  600 B displays (e.g., re-displays) noise user interface  610 A. In some embodiments, in response to receiving a user input selecting one of the mute affordances  630  and  632  or a dismiss affordance, device  600 B displays (e.g., re-displays) user interface  608 A or another user interface on display  602 A. In some embodiments, selection of one of the mute affordances  630  and  632  causes device  600 B to suppress (e.g., to forgo displaying noise notification user interface  610 B despite a notification triggering condition being detected by device  600 B) subsequent notifications for a predetermined auto-suppression period (e.g., time periods corresponding to the time periods displayed at mute affordances  630  and  632 , 1-hour, today, etc.). In some embodiments, notification user interface  610 B includes a graphical indication of a noise exposure level (e.g. noise meter indicator  620 ). 
       FIG.  6 E  depicts noise user interface  610 A after the user has enabled sound reduction function of headphones  600 A, while remaining in the same environment with a 90 dB ambient noise level. User interface  610 A includes sound reduction indicator  638  (e.g., “level reduced by ear pods”) that informs the user that headphones  600 A (“EAR PODS”) are reducing the ambient noise level.  FIG.  6 E  further depicts that the environmental sound level is being reduced to a perceived noise level (e.g., a noise level experienced by a user of the sound reduction device (e.g., headphones  600 A)), as indicated by noise level indicator  618  to be 76 dB. User noise interface  610 A further includes selectable option  624 , which displays an indication that the perceived sound level is safe (e.g., “Long term exposure to sound at this level should not affect your hearing”). 
       FIG.  6 F  depicts user interface  610 A while the environmental sound level is being actively reduced by headphones  600 A to a perceived noise level indicated by noise level indicator  618  to be 76 dB. Noise status indicator  622 A is shown displayed on user interface  610  and textually and graphically (e.g., check-mark symbol) indicates that long-term exposure to sound at this level (e.g., 76 dB) will not affect the user&#39;s hearing. Noise status indicator also includes selectable “Learn More” option  624 . In response to receiving a touch input on option  624 , the user can scroll the noise status indicator  622 A using rotatable and depressible input mechanism  604  to read the additional text illustrated below option  624 , which indicates to the user that the sound level without headphones  600 A is above a safe level, but that with headphones  600 A the sound level is not damaging to the user&#39;s hearing. 
     In  FIG.  6 G , the ambient sound level has increased to 101 dB.  FIG.  6 G  depicts user interface  610 A while the environmental sound level (101 dB) is being actively reduced by headphones  600 A to a perceived noise level indicated by noise level indicator  618  to be 86 dB. Noise status indicator  622 B indicates that repeated long-term exposure to sound at this level (e.g., 86 dB) can damage the user&#39;s hearing. In response to receiving a touch input on option  624 , the user can scroll the noise status indicator  622 A to read the additional text illustrated below option  624 , which indicates to the user that the sound level without headphones  600 A is above a safe level (e.g., 101 dB), and that with headphones  600 A the sound level is still above a safe level. 
     As depicted in  FIG.  6 H  watch  600 B displays noise notification user interface  610 B including noise notification  626 B. Noise notification  626 B textually indicates to the user that the user was exposed to sound levels of 90 dB, that hearing loss can result from being exposed to such sound levels, and that the measurement presented takes into account a sound reduction effect from wearing the headphones  600 A. Additionally, noise notification  626 B provides a textual suggestion to the user to use hearing protection or to move to a less noisy area (e.g., consider using hearing protection or moving to a quieter area). 
     In  FIG.  6 H , noise notification user interface  610 B includes an explanation of what a loud environment consists of, an explanation of the damage to hearing that can be done from exposure to the loud environment, and suggestions for limiting exposure to the loud environment (e.g., “considering using hearing protection”). Noise notification  626 A includes portions that extend beyond noise notification user interface  610 B displayed on display  602 A and that are accessed in response to device  600 B receiving user inputs at depressible input mechanism  604  (e.g., a scroll input). In response to receiving the inputs, device  600 B displays additional portions of noise notification  626 A of noise notification user interface  610 B as depicted in  FIG.  6 D . 
       FIG.  6 I  depicts watch  600 B and phone  600 C displaying corresponding noise notification  626 A and phone noise notification  634  when watch  600 B and phone  600 C are in communication and a noise notification has been generated by a noise level condition that exceeds the predetermined noise level criteria. In some embodiments, noise notification  626 A and phone noise notification  634  are the same. In some embodiments, phone noise notification  634  includes additional information not included with noise notification  626 A. 
       FIG.  7    is a flow diagram illustrating a method  700  for managing and visualizing sound reduction, in accordance with some embodiments. Method  700  is performed at a computer system (e.g.,  100 ,  300 ,  500 ,  600 B,  600 C) (e.g., a smart watch, a smart phone, a personal computer, a laptop, a tablet) that is in communication with a display generation component (e.g.,  602 A,  602 B) (e.g., an integrated display and/or a connected display). In some embodiments, the computer system is tablet, phone, laptop, desktop, a head mounted display (“HMD”), device with a mechanical wheelbase, self-propelled device, smart speaker, personal assistive device, robot, and/or camera. Some operations in method  700  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  700  provides an intuitive way for managing and visualizing sound reduction. The method reduces the cognitive burden on a user for managing and visualizing sound reduction, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to determine the level of sound they are being exposed to while using a sound reduction device and while not using the sound reduction device faster and more efficiently conserves power and increases the time between battery charges. 
     The computer system, while a detected environmental noise level (e.g., a currently detected level, previously detected (e.g., recently detected) level, a level over a period of time (e.g., the last 10 seconds, 1 minute, or 5 minutes)) is at a first noise level (e.g., a level measured in decibels; an unmodified, ambient detected noise level), in accordance with a determination that a set of one or more sound reduction criteria are met, displays ( 702 ), via the display generation component, a user interface (e.g.,  610 A) (e.g., an interface of a noise level monitoring application; an interface of a noise level notification) that includes an indication (e.g.,  618 ,  620 ,  620 A) (e.g., a graphical indication and/or a textual indication) that indicates a second noise level that is lower than the first noise level when (e.g., because, as a result of, and/or caused by) a first user (e.g., a user associated with an account logged into the system; a user that is detected via one or more sensors of the system and/or connected to the system) of the computer system is using a sound reduction device (e.g.,  600 A) (e.g., noise-canceling/noise mitigating headphones, passive earplugs, and/or active earplugs)(e.g., lower based on a detected or estimated amount of noise reduction provided by the sound reduction device). In some embodiments, the environmental noise level is detected by an acoustic sensor (e.g., a microphone) that is in communication with the computer system (e.g., an integrated sensor, a separate sensor connected to the system). In some embodiments, the system is in communication with two or more acoustic sensors that includes an acoustic sensor that detects unmodified, ambient noise and a sensor that detects ambient noise, as modified by the sound reduction device. In some embodiments, the indication also indicates (e.g., graphically or textually) that the second noise level is a modified noise level. 
     The computer system, while the detected environmental noise level is at the first noise level, in accordance with a determination that the set of one or more sound reduction criteria are not met (e.g., as shown in  FIG.  6 C ), displays ( 704 ), via the display generation component, a second user interface (e.g.,  610 A) that indicates the first noise level (e.g., indicates an unmodified/unreduced noise level) (e.g.,  618  and  620 A of  FIG.  6 C ). In some embodiments, the second user interface includes one or more graphical elements that are also in the first user interface. Automatically displaying the indication that indicates the first noise level or the second noise level, based on whether the set of criteria are met provides the user with information about whether sound reduction is in effect. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that a set of one or more sound reduction criteria are met (e.g., as shown in  FIG.  6 E ), the first user interface includes an indication (e.g.,  638 ) (e.g., a textual or graphical indication) that the second noise level is based on use of the sound reduction device, and in accordance with a determination that the set of one or more sound reduction criteria are not met, the second user interface does not include the indication that the second noise level is based on use of the sound reduction device. In some embodiments, the second user interface includes an indication that the first noise level is an environmental noise level and/or an unmodified noise level. Including an indication that the second noise level is based on use of the sound reduction device when certain criteria are met allows the user to quickly recognize when the indication takes into account sound reduction. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, while displaying the first user interface, the computer system detects that the user of the computer system is no longer using the sound reduction device, and in response to detecting that the user of the computer system is no longer using the sound reduction device, the display generation component displays an indication (e.g.,  626 A) (e.g., a textual (e.g., “Sound reduction is not active) or graphical indication) that sound reduction is not active. In some embodiments, the computer system detects that the set of one or more sound reduction criteria are no longer met. In some embodiments, the display generation component transitions to display the second user interface. Automatically displaying an indication that sound reduction is not active when certain conditions are met, automatically provides the user with visual feedback of the change in sound reduction status. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, while displaying the first user interface, the computer system detects that the set of one or more sound reduction criteria are no longer met, and in response to detecting that the set of one or more sound reduction criteria are no longer met, replaces the first user interface (e.g.,  610 A of  FIG.  6 C ) with the second user interface (e.g.,  610 A of  FIG.  6 E ). Automatically updating the indication from the second noise level to the first noise level when the set of one or more criteria are no longer met, automatically provides the user with visual feedback of the change in sound reduction status. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the set of one or more sound reduction criteria are met, the first user interface further indicates (e.g., in addition to indicating the second sound level) the first noise level (e.g., the indication indicates the first noise level and the second noise level) (e.g., as seen in  FIG.  6 G  (“the sound level without Ear Pods is 101 dB). Automatically including an indication of the first noise level (e.g., the environmental noise level) and the second noise level (e.g., the reduced noise level) when criteria are met provides the user with feedback as to both noise levels, allowing the user to compare them. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the set of one or more sound reduction criteria are met and in accordance with a determination that the second noise level exceeds a first noise level threshold (e.g., a safe noise level threshold), the first user interface further indicates (e.g., via  622 B,  626 A, and  626 B) (e.g., textually, graphically) that the noise level threshold has been exceeded (e.g., “around 30 min at this level can cause temporary hearing loss.”). Automatically including an indication that a noise level threshold has been exceeded when criteria are met provides the user with feedback as to both noise levels, allowing the user to compare them. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the set of one or more sound reduction criteria are met and in accordance with a determination that the second noise level exceeds a second noise level threshold (e.g., a safe noise level threshold; a threshold that is the same or different from the first noise level threshold), including, in the first user interface a first selectable graphical object (e.g.,  624 ), that when selected, causes display (e.g., launches the application) of a user interface (e.g.,  610 B) of a hearing-related application (e.g.,  614 ) (e.g., an application that includes information and/or one or more functions related to monitoring hearing), and a second selectable graphical object (e.g.,  628 ,  630 ,  632 ), that when selected, initiates a process to suppress one or more noise-related notifications (e.g.,  622 B) (e.g., future notifications that would be issued, if not suppressed, when one or more noise-related criteria are met (e.g., when a safe noise level is exceeded)). In some embodiments, the user interface further includes an indication (e.g., textual or graphical) to take steps to reduce the noise level (e.g., to move to a less noisy location). Automatically providing selectable options to open a hearing-related application and to manage noise-related notifications when certain criteria are met provides the user relevant functionality and feedback as to the criteria being met. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, while the first noise level (e.g., the environmental noise level) is above a third noise threshold (e.g., a safe noise level threshold; a threshold that is the same or different from the first or second noise level thresholds): in accordance with a determination that the set of one or more sound reduction criteria are not met, including, in the second user interface, an indication (e.g.,  622 A) (e.g., a graphical or textual indication) that the first noise level (e.g., the environmental noise level) has exceeded the third noise threshold, and in accordance with a determination that the set of one or more sound reduction criteria are met and a determination that the second noise level (e.g., the noise level as reduced by a sound reduction effect) is not above the third noise threshold, forgoing including, in the first user interface, an indication (e.g.,  622 B) that the second noise level has exceeded the third noise threshold. In some embodiments, in accordance with a determination that the set of one or more sound reduction criteria are met and a determination that the second noise level is above the third noise threshold, including, in the first user interface, an indication that the second noise level has exceeded the third noise threshold. Automatically including or not including indications that a noise level (e.g., the first or second) is above a threshold noise level provides the user with relevant feedback, when certain conditions are met. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the set of one or more sound notification criteria are met: issuing a first notification (e.g.,  626 A) (e.g., a visual, audio, and/or haptic notification) based on the set of one or more sound notification criteria being met (e.g., a notification that a safe sound level threshold has been exceeded), and initiating a process (e.g., by transmitting data and/or instructions to the external computer system) to cause an external computer system (e.g.,  600 C) that is in communication with the computer system to issue a second notification (e.g.,  634 ) (e.g., a visual, audio, and/or haptic notification) based on the set of one or more sound notification criteria being met (e.g., a notification that a safe sound level threshold has been exceeded). In some embodiments, the set of one or more sound notification criteria include a criterion that is met when the first and/or the second noise levels exceed a fourth noise threshold (e.g., a safe noise level threshold; a threshold that is the same or different from the first, second, and/or third noise level thresholds)). Automatically causing notifications to be automatically issued when criteria are met provides the user with feedback as to a potentially relevant event. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the computer system is in communication with one or more audio sensors (e.g.,  606 ) (e.g., microphones), the first and second noise levels are detected via the one or more audio sensors, and the sound reduction device is an external sound reduction device (e.g.,  600 A) (e.g., external noise-canceling/noise mitigating headphones, passive earplugs, and/or active earplugs). 
     Note that details of the processes described above with respect to method  700  (e.g.,  FIG.  7   ) are also applicable in an analogous manner to the methods described below. For example, methods  900  and  1000  optionally includes one or more of the characteristics of the various methods described above with reference to method  700 . For example, the environmental sound level graph with a sound reduction option elements of method  900  and the sound reduction graph elements of method  1000  can be combined with the indication of a noise level a user is exposed to while using a sound reduction device or not using a sound reduction device elements of method  700  within one or more user interfaces of one or more of user devices  600 B and  600 C. For brevity, these details are not repeated below. 
       FIGS.  8 A- 8 H  depict device  800  displaying user interfaces (e.g., user interface  802 A- 802 H) on display  602 B for accessing and displaying noise exposure data for a user, including environmental noise data (e.g., the noise level of the environment the user is in) and sound reduction noise data (e.g., the noise level of the environment the user is in reduced by a sound reduction effect produced by a sound reduction device being worn by the user). 
       FIG.  8 A  illustrates the user who is wearing headphones  600 A, watch  600 B, and using phone  600 C, similar to what was shown in  FIG.  6 A . In  FIG.  8 A , phone  600 C is displaying a home screen  802 A. As depicted in  FIG.  8 A , phone  600 C receives input  804 A from the user at the health affordance illustrated on home screen  802 A, and in response, displays health user interface  802 B, as shown in  FIG.  8 B . 
       FIG.  8 B  illustrates health user interface  802 B displayed on display  602 B of phone  600 C for accessing user health data.  FIG.  8 B  further depicts phone  600 C receiving input  804 B at hearing affordance  806 . Upon detecting this input, phone  600 C displays hearing user interface  802 C as depicted in  FIG.  8 C . 
       FIG.  8 C  depicts phone  600 C displaying hearing user interface  802 C on display  602 B, in response to the input received at hearing affordance  806 . Hearing user interface  802 C includes various affordances for accessing, displaying, and manipulating noise data (e.g., environmental noise data and sound reduction noise data) over a selectable period of time (e.g., day, week, month, year, etc.).  FIG.  8 C  depicts phone  600 C receiving user input  804 C at environmental sound levels affordance  808 A and receiving user input  804 D at environmental sound reduction affordance  808 B. In response to detecting user input  804 C, phone  600 C displays sound level user interfaces  802 D and  802 E illustrated in  FIGS.  8 D- 8 E . In response to detecting user input  804 D, phone  600 C displays sound reduction user interfaces  802 F- 802 H illustrated in  FIGS.  8 F- 8 H . 
       FIGS.  8 D- 8 E  depict sound level exposure user interfaces  802 D and  802 E, respectively, including graph  814 A and  814 B displaying noise exposure data (e.g., amplitudes or levels of noise that the user has been exposed to) for a time period that is selectable via the time period icons  810  (e.g., hour, day, week, month, 6 months, year). 
     As depicted in  FIG.  8 D , noise exposure data associated with a week is selected via user input (e.g., a tap) on the “W” of the time period icons  810 . In response to detecting the selection of the “W”, phone  600 C bolds the “W” icon and updates graph  814 A to display sound level exposure with sound reduction for the user for a period of a week in order to provide a visual indication of the noise exposure data determined by watch  600 B. 
     As depicted in  FIG.  8 D , exposure indication  816 A indicates, graphically (e.g., via the “check mark”) and textually (e.g., “Exposure OK”) that the sound level exposure for the user of the phone  600 C is at an exposure level that is considered to not be harmful (e.g., below 80 dB, etc.) for the selected period (e.g., week). Sound level exposure user interface  802 D further includes various affordances for manipulating sound exposure data displayed by graph  814 A (e.g., exposure with sound reduction affordance  812 A).  FIG.  8 D  depicts “Exposure with Sound Reduction” affordance  812 A as bolded, indicating that affordance  812 A is currently selected (e.g., selected via user input). In response to the selection of affordance  812 A, graph  814 A displays sound level exposure for the user that is the result of a sound reduction effect via headphones  600 A (e.g., a sound level exposure that is less than the environmental sound level of the environment that the user was present in at the relevant time). 
     As depicted in  FIG.  8 D , graph  814 A displays the time along the X-axis (e.g., the day, “SUN”, “MON”, etc.) and decibels along the Y-axis (e.g., 0 to 100 dB). A plot of the measured sound level exposures for each day of the week is displayed on graph  814 A as a visual indicator of the sound level exposure for each day of the period for the user. Additionally, as depicted in  FIG.  8 D , a straight line extending parallel to the X-axis of graph  814 A corresponds to an average sound level exposure with sound reduction (e.g., 76 dB) for the time period (e.g., week). In some embodiments, the line corresponds to a median of the sound level exposure with sound reduction. 
     As depicted in  FIG.  8 D , the various affordances for manipulating sound exposure data further include Exposure with Sound Reduction affordance  812 B, Daily Averages affordance  812 C, Latest Affordance  812 D, Range affordance  812 E, and Noise Notifications affordance  812 F. As shown in  FIG.  8 E , selecting the Exposure with Sound Reduction affordance  812 B results in graph  814 B displaying a graphical representation of the level of sound exposure that the user of the phone  600 C would have been exposed to if the sound reduction effect of the headphones  600 A was not enabled. Daily Averages affordance  812 C displays the daily averages for the sound level exposure that the user is exposed to for the period. In some embodiments, Daily Averages affordance  812 C displays a range of daily sound level exposure averages including the lowest daily average and the highest daily average sound level exposure for the user. In some embodiments, in response to selection of Daily Averages affordance  812 C, additional information related to the daily averages of the sound level exposure is displayed on display  602 B. 
     As depicted in  FIG.  8 D , Latest Affordance  812 D displays the latest noise level data and the time that the noise level data was determined (e.g., “4:25 AM 52 dB). In some embodiments, in response to selection of Latest Affordance  812 D, phone  600 C displays additional information related to the latest sound level exposure data. Range affordance  812 E displays a range of sound levels (e.g., 46-102 dB) that the user has been exposed to during the selected period (e.g., week). In some embodiments, in response to selection of Range affordance  812 E, phone  600 C displays additional information related to the range of sound level exposure data. Noise Notifications affordance  812 F displays the number of noise notifications (e.g., 1) that have been generated during the selected time period (e.g., week). In some embodiments, in response to selection of Noise Notifications affordance  812 F, phone  600 C displays additional information related to the noise notifications (e.g., historical notification data, notification setup, etc.). 
     As depicted in  FIG.  8 E , the noise exposure data associated with the week remains selected. In response to selection of Exposure without Sound Reduction affordance  812 B, graph  814 B displays sound level exposure without sound reduction (e.g., environmental sound level) for the user for the period of the week in order to provide a visual indication of the noise exposure data determined by the wearable user device (e.g., watch)  600 B. 
     As depicted in  FIG.  8 E , exposure indication  816 B indicates, graphically (e.g., via the triangle with an exclamation mark symbol) and textually (e.g., “Exposure Loud”) that the sound level exposure for the user of phone  600 C is at an exposure level that is considered to be loud (e.g., potentially harmful to the user, above 80 dB, etc.) for the selected period (e.g., week). Due to the selection of affordance  812 B, graph  814 B displays sound level exposure for the user for the week that corresponds to the environmental sound level for the environment the user was in throughout the week (e.g., the sound level exposure does not take into account a sound reduction effect via headphones  600 A for the time period). As also depicted in  FIG.  8 E , the straight line illustrated on graph  814 B corresponds to an average sound level exposure without sound reduction (e.g., 82 dB) for the time period (e.g., week) for the user of phone  600 C. 
       FIGS.  8 F- 8 H  depict sound reduction effect user interfaces  802 F- 802 H, respectively, including graphs  814 C,  814 D, and  814 E which display sound reduction effect data (e.g., amplitudes or levels of sound reduction generated by earphones  600 A) for a time period that is selectable via time period icons  810  (e.g., hour, day, week, month, 6 months, year, etc.). 
     As depicted in  FIG.  8 F , sound reduction effect data associated with a week is displayed in graph  814 C of sound reduction user interface  802 F. Graph  814 C displays the time along the X-axis (e.g., the day, “SUN”, “MON”, etc.) and decibels along the Y-axis (e.g., 0 to 20 dB). Points displayed on graph  814 C represent an active (e.g., variable in response to environmental sound levels in order to attempt to maintain a sound level perceived by the user of headphones  600 A) sound reduction effect (e.g., the amount of sound cancellation produced by earphones  600 A) for each day of the week of the period for the user wearing earphones  600 A. Additionally, as depicted in  FIG.  8 F , a straight line extending parallel to the X-axis of graph  814 C corresponds to an average sound reduction effect (e.g., 10 dB) for the time period (e.g., week). In some embodiments, the line corresponds to a median of the sound reduction effect. 
     As depicted in  FIG.  8 F , graph  814 A displays the time along the X-axis (e.g., the day, “SUN”, “MON”, etc.) and decibels along the Y-axis (e.g., 0 to 100 dB). A plot of the measured sound level exposures for each day of the week is displayed on graph  814 A as a visual indicator of the sound level exposure for each day of the period for the user. Additionally, as depicted in  FIG.  8 D , a straight line extending parallel to the X-axis of graph  814 A corresponds to an average sound level exposure with sound reduction (e.g., 76 dB) for the time period (e.g., week). In some embodiments, the line corresponds to a median of the sound level exposure with sound reduction. As depicted in  FIG.  8 F , range indicator  818 A displays a range of sound reduction effects (e.g., an amount of sound cancellation produced by earphones  600 A) that the user has experienced via earphones  600 A during the selected (e.g., week). 
       FIG.  8 F  depicts receiving user input  804 E (e.g., a tap) on the “D” (e.g., day) representation of time period icons  810  (e.g., hour, day, week, month, 6 months, year, etc.) and receiving user input  804 F on “Latest” affordance  820 . As depicted in  FIG.  8 G , in response to selection of the “D” icon of sound reduction user interface  802 G, the “D” icon is bolded and graph  814 D displays sound reduction effects from earphones  600 A for a single day. As also depicted in  FIG.  8 G , in response to selection of “Latest” affordance  820 , the chronologically most recent sound reduction effect data point on graph  814 D is bolded. 
     As depicted in  FIG.  8 G , active sound reduction effect data associated with a day is displayed in graph  814 D. Range indicator  818 B displays a range of sound reduction effects that the user has experienced via earphones  600 A during the selected period(e.g., day). Graph  814 D includes a textual summary of the points displayed on graph  814 D represent an active sound reduction effect determined at a time in four hour intervals throughout a day. Additionally, as depicted in  FIG.  8 G , a straight line extending parallel to the X-axis of graph  814 D corresponds to an average sound reduction effect (e.g., 10 dB) for the time period (e.g., day). In some embodiments, the line corresponds to a median of the sound reduction effect. 
     As depicted in  FIG.  8 H , constant sound reduction effect (e.g., the sound reduction effect of earphones  600 A is a constant amount that does not vary with environmental sound levels where the user and/or watch  600 B are located) data associated with a day is displayed in graph  814 E. Points displayed on graph  814 E represent a constant sound reduction effect determined at a time at four hour intervals throughout a day. 
       FIGS.  9 A- 9 B  are a flow diagram illustrating a method  900  for managing and visualizing sound reduction, in accordance with some embodiments. Method  900  is performed at a computer system (e.g.,  100 ,  300 ,  500 ,  600 B,  600 C) (e.g., a smart watch, a smart phone, a personal computer, a laptop, a tablet) that is in communication with a display generation component (e.g.,  602 A,  602 B) (e.g., an integrated display and/or a connected display). In some embodiments, the computer system is tablet, phone, laptop, desktop, a head mounted display (“HMD”), device with a mechanical wheelbase, self-propelled device, smart speaker, personal assistive device, robot, and/or camera. Some operations in method  900  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     The computer system displays ( 902 ), via the display generation component, a representation (e.g.,  814 A,  814 B) (e.g., a graph, a chart) of a noise level (e.g., the noise level in the environment that the system and/or a user of the system was in at the time) at a plurality of different times (e.g., different times in a given day, different days of the week, different weeks in a year). 
     The representation includes, in accordance with a determination that a sound reduction display option (e.g.,  812 A) is enabled (e.g., enabled via user input on an affordance): a first indication of a noise level at a first time (e.g.,  810 ) (e.g., a first day (e.g., a Monday)) of the plurality of different times that indicates ( 904 ), in accordance with a determination that sound reduction was in effect at the first time (e.g., that the user (e.g., a user associated with an account logged into the system; a user that is detected via one or more sensors of the system and/or connected to the system) of the computer system was using a sound reduction device (e.g., noise-canceling/noise mitigating headphones, passive earplugs, and/or active earplugs)), a first noise level, wherein the first noise level is based on an environmental noise level at the first time (e.g., a detected level, previously detected (e.g., recently detected) level, or a level over a period of time (e.g., the last 10 seconds, 1 minute, or 5 minutes) that are associated with the first time; an average, median, maximum, minimum or modal noise level over a period of time that is the first time (e.g., a day)) and a first sound reduction effect that was in effect at the first time, and in accordance with a determination that sound reduction was not in effect at the first time, a second noise level (e.g., an unmodified environmental noise level) that is greater than the first noise level, wherein the second noise level is based (e.g., only, solely) on the environmental noise level at the first time, a second indication of a noise level at a second time (e.g., a second day (e.g., a Tuesday)) of the plurality of different times that is different from the first time and that indicates ( 906 ), in accordance with a determination that sound reduction was in effect at the second time, a third noise level, wherein the third noise level is based on an environmental noise level at the second time and a second sound reduction effect that was in effect at the second time, and in accordance with a determination that sound reduction was not in effect at the second time, a fourth noise level that is greater than the third noise level, wherein the fourth noise level is based (e.g., only, solely) on the environmental noise level at the second time.

In some embodiments, the sound reduction option is a selectable option that is separate from an option for not displaying sound reduction. In some embodiments, the second noise level is based on the environmental noise level at the first time and is not based on the first sound reduction effect that was in effect at the first time. In some embodiments, the second noise level is not based on any sound reduction effect that was in effect at the first time. In some embodiments, the fourth noise level is based on the environmental noise level at the second time and is not based on the second sound reduction effect that was in effect at the first time. In some embodiments, the fourth noise level is based on the environmental noise level at the second time and is not based on any sound reduction effect that was in effect at the first time. 
     The representation includes, in accordance with a determination that the sound reduction display option is not enabled (e.g., via selection of  812 B) (e.g., is disabled or that a display without sound reduction option is enabled), a third indication of a noise level at the first time that indicates ( 908 ) the second noise level, and a fourth indication of a noise level at the second time that indicates ( 910 ) the fourth noise level. In some embodiments, the third indication of the noise level at the first time indicates the second level of environmental noise regardless of whether sound reduction was in effect at the first time. In some embodiments, the fourth indication of the noise level at the second time that indicates the fourth level of environmental noise regardless of whether sound reduction was in effect at the second time.

     In some embodiments, the one or more audio sensors are integrated into an external computer system (e.g.,  600 B) (e.g., a smart watch) that is in communication with the computer system, and the representation of the noise level at the plurality of different times is included in a user interface (e.g.,  802 D,  803 E) of a health application (e.g.,  614 ) that generates (e.g., manages, includes) a plurality of user interfaces based on biometric data of a user of the computer system. Including the representation of the noise level at a plurality of different times as part of a health application provides the user with feedback as to various biometric parameters relevant to the user&#39;s health. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, while the sound reduction display option is not enabled, the third indication is a graphical indication that varies along a first axis (e.g., a vertical axis) to indicate a range of environmental noise levels at the first time (e.g., range of noise levels detected during a specific hour, day, or week), the fourth indication is a graphical indication that varies along the first axis to indicate a range of environmental noise levels at the second time, the third indication and fourth indication are arranged along a second axis, different from the first axis (e.g., a horizontal axis), and the representation (e.g.,  814 B) of the noise level at the plurality of different times includes a first average noise level indication (e.g., a horizontal line that varies in the vertical direction to indicate the average noise level over the plurality of times) that extends along the second axis and that indicates the average environmental noise level during the plurality of different times. In some embodiments, the first, and/or second indications is a graphical indication that varies along a first axis to indicate a range of environmental noise levels at the first time. Providing indicators of the range of noise levels at various times as well as the average noise levels at those times provides the user with feedback as to the detected noise levels. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, while the sound reduction display option is enabled, the first indication is a graphical indication and includes a first subportion that varies along a third axis (e.g., a vertical axis) and indicates a range of the noise level at the first time, as reduced by the first sound reduction effect at the first time (e.g., a range of the modified/reduced noise level detected during the first time), the second indication is a graphical indication that includes a second subportion that varies along the third axis and indicates a range of the noise level at the second time, as reduced by the second sound reduction effect at the second time (e.g., a range of the modified/reduced noise level detected during the first time), the first indication and second indication are arranged along a fourth axis, different from the third axis (e.g., a horizontal axis), and the representation (e.g.,  814 A) of the noise level at the plurality of different times includes a second average noise level indication (e.g., a horizontal line that varies in the vertical direction to indicate the average reduced noise level over the plurality of times) that extends along the fourth axis and that indicates the average noise level during the plurality of different times, as reduced by the first sound reduction effect during the plurality of different times. Providing indicators of the range of reduced noise levels at various times as well as the average reduced noise levels at those times provides the user with feedback as to the detected noise levels and the amount of sound reduction. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first indication includes a third subportion that varies along the third axis and indicates a range of environmental noise levels at the first time, the second indication includes a fourth subportion that varies along the third axis and indicates a range of environmental noise levels at the second time, and the representation (e.g.,  814 A) of the noise level at the plurality of different times includes a third average noise level indication (e.g., a horizontal line that varies in the vertical direction to indicate the average reduced noise level over the plurality of times) that extends along the fourth axis and that indicates the average environmental noise level during the plurality of different times. Providing indicators of the range of reduced and environmental noise levels at various times as well as the average reduced and environmental noise levels at those times provides the user with feedback as to the detected noise levels and the amount of sound reduction. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the determination that sound reduction was in effect at the first time includes a determination that a user of the computer system was wearing (e.g., using) a sound reduction device (e.g.,  600 A of  FIGS.  6 A and  8 A ) (e.g., noise-canceling/noise mitigating headphones, passive earplugs, and/or active earplugs in both ears) for both ears. In some embodiments, using only one headphone, even if sound reduction is enabled for that headphone, results in a determination that sound reduction was not in effect. Displaying indications of reduced sound levels only when both ears are affected by sound reduction automatically provides users with information about the sound levels experienced by either ear and provides feedback as to the same. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently.

Providing an indication of the maximum detected noise level during a period of interest provides a user with feedback as to sounds detected during that period. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently.

Providing an indication of sound-related notifications for a period provides a user with feedback as to such notifications that were issued during that period. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the representation of the noise level at the plurality of different times includes an indication (e.g.,  812 E) of a range of noise levels (e.g., range of environmental and/or reduced levels; a minimum and a maximum level) detected during the plurality of different times.

     Note that details of the processes described above with respect to method  900  (e.g.,  FIGS.  9 A- 9 B ) are also applicable in an analogous manner to the methods described above/below. For example, methods  700  and  1000  optionally includes one or more of the characteristics of the various methods described above with reference to method  900 . For example, the environmental sound level graph with a sound reduction option elements of method  900  and the sound reduction graph elements of method  1000  can be combined with the indication of a noise level a user is exposed to while using a sound reduction device or not using a sound reduction device elements of method  700  within one or more user interfaces of one or more of user devices  600 B and  600 C. For brevity, these details are not repeated below. 
       FIG.  10    is a flow diagram illustrating a method  1000  for managing and visualizing sound reduction, in accordance with some embodiments. Method  1000  is performed at a computer system (e.g.,  100 ,  300 ,  500 ,  600 B,  600 C) (e.g., a smart watch, a smart phone, a personal computer, a laptop, a tablet) that is in communication with a display generation component (e.g.,  602 A,  602 B) (e.g., an integrated display and/or a connected display). In some embodiments, the computer system is tablet, phone, laptop, desktop, a head mounted display (“HMD”), device with a mechanical wheelbase, self-propelled device, smart speaker, personal assistive device, robot, and/or camera. Some operations in method  1000  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     The computer system displays ( 1002 ), via the display generation component, a first representation (e.g.,  814 C) (e.g., a graph, a chart) of a sound reduction level (e.g., a sound reduction level based on a sound reduction effect (e.g., a passive or active effect)) (e.g., an amount of sound reduction by a sound reduction device (e.g., noise-canceling/noise mitigating headphones, passive earplugs, and/or active earplugs)) for a first time period (e.g.,  810 ) corresponding to a first plurality of times, (e.g., times when a user of the computer system was using the sound reduction device at the two or more different times) wherein the first representation includes a first indication of a sound reduction level (e.g., a quantitative indication (e.g., a value in decibels of sound reduced)) (e.g., a first day (e.g., a Monday)) (e.g., the first time is one of the times of the first plurality of different times) at a first time of the first plurality of times (e.g., a day, a week, a month, a year) (e.g., different times in a given day, different days of the week, different weeks in a year), and a second indication (e.g., a quantitative indication (e.g., a value in decibels of sound reduced) of a sound reduction level at a second time of the first plurality of times that is different from the first time. In some embodiments, the indication is an indication of an instantaneous amount of sound reduction at the first time. In some embodiments, the first time is range of time (e.g., a day) and the indication is an indication of an average amount of sound reduction over that range of time). In some embodiments, the indication is an indication of an instantaneous amount of sound reduction at the second time. In some embodiments, the second time is range of time (e.g., a day) and the indication is an indication of an average amount of sound reduction over that range of time. 
     The computer system, while displaying the first representation, receives ( 1004 ), via the one or more input devices, a set of one or more inputs ( 804 E,  804   f ) (e.g., enabled via user input on an affordance) corresponding to selection of a display option for a second time period (e.g., a day, a week, a month, a year) corresponding to a second plurality of times that is different from the first plurality of times. In some embodiments, the display option for the first time period option is an affordance that allows a user to select a specific time period, such as a day, a week, or a month. In some embodiments, the option is a selectable option that is separate from additional options/affordances for displaying different time periods. 
     The computer system, in response to receiving the set of one or more inputs, displays ( 1006 ), via the display generation component, a second representation (e.g.,  814 D,  814 E) of a sound reduction level at the second plurality of times, wherein the second representation includes a third indication of a sound reduction level at a third time of the second plurality of times, a fourth indication of a sound reduction level at a fourth time of the second plurality of times that is different from the third time. In some embodiments, the third time and/or the fourth time is a subset of the first time (e.g., the first time is a week and the third time is a day within that week (e.g., the indications in the second representation of a sound reduction level are more granular than the indications in the first representation of a sound reduction level)). In some embodiments, the first time and/or the second time is a subset of the third time (e.g., the first time is a first day of the week and the second time is a second day of the week with the third time being the entire week). 
     In accordance with a determination that the display option (e.g., “D” as shown in  FIGS.  8 F- 8 H ) for the second time period corresponds to a first display option (e.g., an option for a shorter time period than the currently displayed time period (e.g., the current time period is a week view and the requested time period is a day view)), the second time period is a subset of the first time period (e.g., the second time period a shorter time period than the first time period and falls within the first time period), in accordance with a determination that the display option for the second time period corresponds to a second display option (e.g., an option for a longer time period than the currently displayed time period (e.g., the current time period is a week view and the requested time period is a month view)), the first time period is a subset of the second time period (e.g., the second time period is a longer time period that includes the entirety of the first time period). Providing a user with options to view sound reduction data for different time periods, via a selectable option, provides the user with additional control options. Providing additional control of the system without cluttering the UI with additional displayed controls enhances the operability of the system and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the computer system is in communication with one or more audio sensors (e.g.,  606 ) (e.g., microphones), and the sound reduction level for the first time period is based on noise detected by the one or more audio sensors, and the sound reduction device is an external sound reduction device (e.g.,  600 A) (e.g., external noise-canceling/noise mitigating headphones, passive earplugs, and/or active earplugs). In some embodiments, the sound reduction level is a difference between noise detected by a first microphone and a noise detected by a second microphone. In some embodiments, the sound reduction level is calculated based on an environmental noise level measured by the one or more audio sensors). 
     In some embodiments, the one or more audio sensors are integrated into an external computer system (e.g.,  600 B) (e.g., a smart watch) that is in communication with the computer system, and the first representation of the sound reduction level for the first time period corresponding to a first plurality of times is included in a user interface (e.g.,  802 B) of a health application (e.g.,  614 ) that generates (e.g., manages, includes) a plurality of user interfaces based on biometric data of a user of the computer system. In some embodiments, the second representation of the sound reduction level for the first time period corresponding to a first plurality of times is included in the user interface of the health application. Including first representation as part of a health application provides the user with feedback as to various biometric parameters relevant to the user&#39;s health. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the sound reduction device provides a dynamic sound reduction effect (e.g., as shown in  FIGS.  8 F- 8 G  at  814 C and  814 D), the first indication of a sound reduction level indicates a level of sound reduction that is different from the level of sound reduction indicated by the second indication of a sound reduction level (e.g., the sound reduction level is 10 decibels for the first time period and 5 decibels at the second time period). Automatically providing indications of different sound reduction levels at different times when the device is capable of providing a dynamic reduction effect automatically provides the user with a more accurate indication, when certain conditions are met. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in accordance with a determination that the sound reduction device provides a static sound reduction effect (e.g., as shown in  FIG.  8 H  at  814 E), the first indication of a sound reduction level and the second indication of sound reduction level indicate the same sound reduction level (e.g., the sound reduction level is 10 decibels for the first time period and 10 decibels at the second time period). Automatically providing indications of the same sound reduction level at different times when the device provides a static sound reduction effect automatically provides the user with an accurate indication, when certain conditions are met. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first representation of the sound reduction level includes an indication (e.g.,  818 A,  818 B,  818 C) of a range (e.g., a minimum value and a maximum value (e.g., 10-30 decibels)) of sound reduction effect for the first time period. Providing an indication of a range of sound reduction for the first time period provides the user with improved feedback as the variations in sound reduction during the first time period. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first representation of the sound reduction level includes an indication of a range (e.g.,  818 C) (e.g., a minimum value and a maximum value (e.g., 10-30 decibels)) of time during which a sound reduction effect was determined to in be in effect during the first time period (e.g., the first time period is the current day and a range of 8 AM to 11 AM is indicated for when the effect was active). Providing an indication of a range of time when the sound reduction effect was active during the first time period provides the user with improved feedback as to the timing of the effect. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first indication of a sound reduction level is a numerical indication of a sound reduction level (e.g., as shown by  818 C in  FIG.  8 H ) (e.g., 10 decibels). Providing a numerical indication of a sound reduction effect provides the user with improved feedback as to magnitude of the effect. Providing improved visual feedback reduces power usage and improves battery life of the system by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, prior to displaying the first representation of the sound reduction level for the first time period, displaying, via the display generation component, a summary user interface (e.g.,  802 B,  802 C) of a health application (e.g.,  614 ) (e.g., an application that presents data and/or functions relating to biometric data of the user of the computer system) that includes a first selectable user interface object (e.g.,  808 B) that corresponds to sound reduction data (e.g., data used to generate the first representation of the sound reduction level at the first time period), and a second selectable user interface object (e.g., a summary of noise/sound related data) that corresponds to a biometric parameter other than sound (e.g., heart rate, sleep, physical activity, menstrual cycle) that, when selected, initiates a process for displaying a user interface corresponding to the biometric parameter other than sound. Prior to displaying the first representation of the sound reduction level for the first time period, receiving, via the one or more input devices, a second set of one or more inputs (e.g.,  804 D) (e.g., taps, swipes, key presses, and/or mouse clicks) that includes an input corresponding to the first selectable user interface object that corresponds to sound reduction, wherein the first representation of the sound reduction level for the first time period is displayed in response to the second set of one or more inputs. Providing the first representation as part of a health application that includes user interfaces for other biometric parameters provides the user with options for viewing other health-related data via separate user interfaces. Providing additional control of the system without cluttering the UI with additional displayed controls enhances the operability of the system and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the first time, the second time, the third time, and the fourth time are equal lengths of time (e.g., as shown in  FIG.  8 F- 8 H )(e.g., all represent an hour, or all represent a day). 
     In some embodiments, in accordance with a determination that the display option for the second time period corresponds to a first display option (e.g., as shown in  FIG.  8 F ), with the second time period being a subset of the first time period, the third time is a shorter time period than the first time period (e.g., the first time period is a day and the third time period is an hour), and in accordance with a determination that the display option for the second time period corresponds to a second display option, with the first time period being a subset of the second time period (e.g., as shown in  FIG.  8 G ), the third time is a longer time period than the first time period (e.g., the first time period is a week and the second time period is a month). Adjusting the period of time represented by the indications (e.g., the third indication) automatically based on the selected option provides the user with different detail levels as the plurality of times (e.g., the time range) changes and feedback as to the relationship between the selected time ranges. Performing an operation when a set of conditions has been met without requiring further user input and providing improved visual feedback both reduce power usage and improve battery life of the system by enabling the user to use the device more quickly and efficiently. 
     Note that details of the processes described above with respect to method  1000  (e.g.,  FIG.  10   ) are also applicable in an analogous manner to the methods described above. For example, methods  700  and  900  optionally includes one or more of the characteristics of the various methods described above with reference to method  1000 . For example, the environmental sound level graph with a sound reduction option elements of method  900  and the sound reduction graph elements of method  1000  can be combined with the indication of a noise level a user is exposed to while using a sound reduction device or not using a sound reduction device elements of method  700  within one or more user interfaces of one or more of user devices  600 B and  600 C. For brevity, these details are not repeated below.

Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of managing and visualizing sound reduction, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide sound reduction-associated data for targeted managing and visualizing sound reduction. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, managing and visualizing sound reduction information can be made available to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the managing and visualizing sound reduction applications , or publicly available information.
