## Background
TECHNICAL FIELD
The present invention generally relates to vehicles and more particularly relates to aircraft manufacturing, testing, and maintenance.
BACKGROUND
Vehicles, such as aircraft and motor vehicles, commonly include components that generate an audible nuisance (i.e., an undesirable noise). Not only is an audible nuisance distracting or annoying to occupants within the vehicle or people outside the vehicle, the audible nuisance may be an indication that the component is malfunctioning. The source of the audible nuisance is commonly due to noises, vibrations, squeaks, or rattling from moving or fixed components of the vehicle. Determining the source of the audible nuisance can be difficult. For example, other noises, such as engine or road noise, may partially mask the audible nuisance making determination of the source difficult. Further, the audible nuisance may only sporadically occur making reproducibility of the audible nuisance to determine the source difficult.
To address this issue, technicians and/or engineers trained to detect and locate audible nuisances commonly occupy the vehicle during a test run in an attempt to determine the source of the audible nuisance. These test runs can be expensive and time consuming. For example, determination of the source of a nuisance noise in an aircraft during a test run commonly requires the usage of additional personnel (e.g., technicians, engineers, and pilots), the usage of additional fuel, and taking the aircraft out of normal service. While this solution is adequate, there is room for improvement.
Accordingly, it is desirable to provide a system for identifying a source of an audible nuisance in a vehicle and a method for the same. Furthermore, other desirable features and characteristics will become apparent from the subsequent summary and detailed description and the appended claims, taken in conjunction with the accompanying drawings and the foregoing technical field and background.

DETAILED DESCRIPTION
The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features. As used herein, the term module refers to any hardware, software, firmware, electronic control component, processing logic, and/or processor device, individually or in any combination, including without limitation: application specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) and memory that executes one or more software or firmware programs, a combinational logic circuit, and/or other suitable components that provide the described functionality.
A system for identifying a source of an audible nuisance in a vehicle is taught herein. In an exemplary embodiment, the system is configured to include a device, such as a smartphone or a tablet, and a dock. The system can be stored onboard an aircraft and utilized by an aircrew member (or by any other person on board the aircraft during the flight) when an audible nuisance is present. In other words, the system can be utilized immediately upon detection of the presence of an audible nuisance by an aircrew member currently onboard the aircraft rather than waiting until a test flight can be performed with specialized crew members and equipment as conventionally performed. In embodiments, the device includes a camera having a camera field of view (FOV) and the dock includes a microphone array having an acoustic FOV with the camera FOV and the acoustic FOV in alignment.
When an audible nuisance is detected, the aircrew member can retrieve the system from storage in the aircraft. Next, the aircrew member can couple the dock to the device. However, it is to be appreciated that the dock may be already coupled to the device during storage. The aircrew member can then orient the microphone array and the camera toward a location proximate the source of the audible nuisance. The source may be located within a compartment that is hidden from view by a wall in an aircraft such that the camera will capture an image of the wall proximate the source and the microphone array will capture the audible nuisance from the source. In embodiments, a soundmap signal is generated from the audible nuisance with the soundmap signal overlaid over the image to generate a camera/soundmap overlay signal. In embodiments, an image of the camera/soundmap overlay signal includes a multicolored shading overlying the location with the presence of the shading corresponding to areas of the location propagating sound and the coloring of the shading corresponding to the amplitude of the sound from the soundmap signal. In embodiments, the device includes a display for displaying the camera/soundmap overlay signal which can be viewed by the aircrew member.
After generating the camera/soundmap overlay signal, the aircrew member can save the camera/soundmap overlay signal in a memory of the device or send the camera/soundmap overlay signal to ground personnel. The aircrew member may then remove the dock from the device and store the system in storage. However, it is to be appreciated that the dock can be coupled to the device during storage. During flight or once the aircraft lands, a technician on the ground can review the camera/soundmap overlay signal and identify the source of the audible nuisance without having to be onboard the aircraft during a test flight.
A greater understanding of the system described above and of the method for identifying a source of audible nuisance in a vehicle utilizing the may be obtained through a review of the illustrations accompanying this application together with a review of the detailed description that follows.
FIG. 1 is a perspective view illustrating a non-limiting embodiment of a system 10 for identifying a source 12 of an audible nuisance 14 in a vehicle. The audible nuisance 14 may be any sound. In some embodiments, audible nuisance 14 may have a frequency of from 20 to 20,000 Hz. It is to be appreciated that while the sound is referred to as an audible “nuisance,” the sound does not necessary have to be undesirable. In other words, the audible nuisance 14 may be a desirable sound. The source 12 of the audible nuisance 14 may be due to noises, vibrations, squeaks, or rattling from moving or fixed components of the vehicle. The source 12 may be hidden from view by an obstruction, such as a wall, a compartment, a panel, a floor, a ceiling, etc.
FIG. 2 is a block diagram illustrating a non-limiting embodiment of the system 10. The system 10 includes a device 16, a dock 18, and a processor module 20. As will be described in greater detail below, the system 10 may further include a battery 22, a listening device 24, a memory 26, a display 28, or combinations thereof.
The device 16 includes a camera 30 configured to receive a visual dataset. The visual dataset may be an image, such as a still image or a video. With continuing reference to FIG. 1, when system 10 is employed to identify an audible nuisance, an operator may use device 16 to obtain a visual dataset from a location 32 proximate the source 12 of the audible nuisance 14. The location 32 proximate the source 12 may include an obstruction that hides the source 12 from view. As one non-limiting example, the source 12 may be located within a compartment that is hidden from view by a wall in an aircraft. In this example, the camera 30 will capture an image of the wall proximate the source 12. The camera 30 is further configured to generate a camera signal 34 in response to the visual dataset.
The dock 18 includes a microphone array 36 configured to receive the audible nuisance 14. In embodiments, the microphone array 36 has a frequency response of from 20 to 20,000 Hz. The microphone array 36 is further configured to generate a microphone signal 38 in response to the audible nuisance 14. In embodiments, the visual dataset received by camera 30 corresponds with the microphone signal 38 generated by the microphone array 36.
The microphone array 36 may include at least two microphones 40, such as a first microphone 40′ and a second microphone 40′′. In embodiments, the first microphone 40′ and the second microphone 40′′ are each configured to receive the audible nuisance 14. Further, in embodiments, the first microphone 40′ is configured to generate a first microphone signal in response to the audible nuisance 14, and the second microphone 40′′ is configured to generate a second microphone signal in response to the audible nuisance 14. It is to be appreciated that each of the microphones 40 may be configured to each receive the audible nuisance, and to each generate a microphone signal 38 in response to receipt of the audible nuisance 14. In embodiments, the microphone array 36 includes microphones 40 in an amount of from 2 to 30, from 3 to 20, or from 5 to 15. In certain embodiments, the first microphone 40′ and the second microphone 40′′ are spaced from each other in a distance of from 0.1 to 10, from 0.3 to 5, or from 0.5 to 3, inches. In other words, in an exemplary embodiment when the microphone array 36 includes fifteen microphones 40, at least two of the fifteen microphones 40, such as the first microphone 40′ and the second microphone 40′′, are spaced from each other in a distance of from 0.1 to 10, from 0.3 to 5, or from 0.5 to 3, inches. Proper spacing of the microphones 40 results in increased resolution of the raw soundmap signal 48. In various embodiments, the microphones 40 are oriented in any suitable pattern, such as a spiral pattern or a pentagonal pattern.

In various embodiments, the angular size of the acoustic FOV 50 will be increased or decreased to render the acoustic FOV 50 and the camera FOV 52 aligned with each other. In one exemplary embodiment, when the camera FOV 52 is disposed within the acoustic FOV 50, the angular size of the acoustic FOV 50 is decreased to align with the camera FOV 52. In another exemplary embodiment, when the acoustic FOV 50 and the camera FOV 52 are partially overlapping, the angular size of the acoustic FOV 50 is decreased to align the acoustic FOV 50 with the camera FOV 52. It is to be appreciated that any properties and/or dimensions of the acoustic FOV 50 and the camera FOV 52 can be adjusted to align the acoustic FOV 50 and the camera FOV 52 with each other. Examples of properties and/or dimensions that can be adjusted includes, but are not limited to, resolutions, bit rates, lateral sizes of the FOVs, longitudinal sizes of the FOVs, circumferences of the FOVs, etc.
