Sound
* All sound is born out of silence
  - caused by vibrations
  - created by vibrations
  - made by vibrations that travel through the air
* All sound is produced by the vibration of matter
  - vibration no matter what the source is
* All sounds are made by vibrations of molecules through which the sound travels
  - waves produced by the vibrations of material objects
* Any sound disturbance in the air.
* Every sound exists in nature.
* Most sound is caused by vibration
  - generated by animals
* Most sound is produced by connective tissue

  - mammal prey
* Some sound is produced by small mammal prey
  - sounds are inaudible to humans but can be heard by other whales thousands of miles away
* affects areas
  - meaning in every word in every language
* also are different in how loud and how soft they are
  - important to a newborn because they are the building blocks of speech and language
  - differ in pitch
* are a direct way of communicating
  - function of their source and their environment
  - air waves which enter through the external ear canal and vibrate the ear drum
  - generated by passing air from the bony nares through the phonic lips
  - metal rods used in the medical community to dilate urethras, male and female
  - one of the information sources available to young learners as they learn to read
  - pictures of the environment, they represent social-political corections
  - produced by objects that vibrate
  - really waves of energy that move through a medium, either water or air
  - the results of vibrations that cause molecules to move back and forth
* are vibrations in air
  - the air that are caused by a vibrating object of some sort
* becomes noise when it is unwanted, bothersome or painful.
* begin as breath expelled from the lungs.
* begins when some physical body, in contact with the air, vibrates.
* can also vary in intensity, which is reflected as loudness
  - be human, machine-made or natural
  - represent words
* carries well at night, in mist, fine rain, and on water.
* carry certain vibrations.
* causes different reaction
* changes perceptions.
* comes from energy
  - kinetic energy
  - monkeys
  - surfaces
  - the vibrations that are produced from one object applying force to another object
  - when two hands meet
* contain energy in different frequency ranges, or bands.
* differ in amplitude and frequency.
* does exist within the earth because sound can go through solids and liquids
  - travel through matter
* emerge in a developmental pattern.
* enters the ear canal or meatus and vibrates the ear drum or tympanum
  - canal, hits the eardrum and causes the small bones in the ear to vibrate
* exists everywhere.
* expressing aggression include growls, woofs, snorts, bellows and roars.
* fill human senses.
* give rise to form and form gives rise to change.
* go dressed in colors, and colors contain music.
* has actions
  - functions
  - huge impact
  - usefulness
  - various functions
* have greater amplitude - on the average, two times the amplitude of obstruents
  - their own innate and complex structures and energies
* help a child learn to communicate.
* helps bats
  - develop brain connections that help a child respond to others
* induces vibration.
* is alive with flow, rhythm, layers of vibration
  - bodies of water
  - capable of penetrating the soul
* is caused by impact
  - channels
  - due to the vibrations of a source, such as a mus
  - emptiness, emptiness is sound, and the wheel of dharma is turned around
  - funnies
  - hears
* is located in air
  - concert halls
  - midi files
  - mouths
  - movies
  - songs
* is longitudinal waves through air
  - magazines
  - mechanical energy, and anything that exhibits movement can make sound
  - natural things
  - nothing more than vibrations moving through a medium
  - physical phenomenons
* is pressure differences in air
  - throats
  - sensation
* is used for alerting
  - vibrational energy
* made from the stridulatory organ can scare away potential predators.
* moves through air.
* needs molecules bumping molecules to transfer the momentum and energy
  - to have a certain degree of both absorption and reflection
* occurs when a body, such as a vocal chord, vibrates, or moves back and forth
  - moving or vibrating object causes the air around it to move
  - within ranges
* pass into our ear and make the eardrum vibrate , which makes the tiny bones inside.
* passes through ears
  - outer ears
* plays a crucial role in the exchange of information in the marine environment
  - an important role during hatching as it triggers maternal behaviour in adult crocodiles
* produced by humans Speak loudly or sing a song or buzz like a bee
  - man make it more difficult for dolphins to function
* produces vibrations that affect matter.
* stands for primal sound.
* suggests echolocation.
* travel down the ear canal and strike the tympanic membrane causing it to vibrate
  - faster in the water than the air, so whales hear sounds quickly, and from far away
* travels almost five times faster in water than in air
  - water than on land, and sharks have keen sense of hearing
* travels better in water than in air
  - through solids and liquids than through air
  - down the ear canal and causes the eardrum to vibrate
  - easily in a vacuum
* travels faster in cold air than warm because cold air is denser
  - liquids than it does in gases
* travels faster in warm air than cold because cold air molecules move more slowly
  - cold because warm air molecules move more quickly
  - water than in cold water
* travels faster in warmer water, slower in cooler water
  - most rapidly through solids
  - much farther, and much faster in water than it does in air
  - normally through the outer and middle ear
* travels slower in air than in water
  - cold air than warm because cold air molecules move more slowly
  - water than in wood
* travels through a medium like air or water as waves of compression and rarefaction
  - air as a series of waves of compressed air
  - air, water, or even a block of steel thus all are mediums for sound
  - all substances, even solid substances
  - cold, dense air more slowly than through warmer, less dense air
  - different kinds of matter
  - matter by vibration
  - most liquids and solids faster than through air
  - very efficiently in water, and the lives of fish and whales revolve around sound
  - well in water and orcas communicate with calls, clicks and whistles
* works with or without the earphones.
+ Bass guitar, Strings and sound: Guitars
  * Sounds are produced from the strings in a number of ways. The most common form of playing is called fingerstyle, in which the player plucks the fingers upwards with the ends of the fingers. It is common to use the index and middle fingers as the plucking fingers, but players may use more fingers or even employ their thumb to pluck downwards.
+ Guqin: Plucked string instruments :: Music in China :: Masterpieces of the Oral and Intangible Heritage of Humanity
  * Sounds are produced by  open strings, stopped strings, and harmonics. By tradition the qin originally had five strings, but ancient qin-like instruments with 10 or more strings have been found. The modern form has been standardized from about two thousand years.
  * All sounds are made by vibrations of molecules through which the sound travels. For instance, when a drum or a cymbal is struck, the object vibrates. These vibrations make air molecules move. When the vibrating air molecules reach our ears, the eardrum vibrates, too. The bones of the ear vibrate in the same way that of the object that started the sound wave. These vibrations let you hear different sounds.
+ Hearing: Sensory system
  * Sounds pass into our ear and make the eardrum vibrate, which makes the tiny bones inside. The bones vibrate a small tube shaped like a snail shell, called the 'cochlea'. Inside the cochlea is a fluid, which moves tiny hairs that send signals to the brain.
