Hertz |
the SI unit of frequency, equal to one cycle per second. |
|
Frequency |
the rate at which something occurs or is repeated over a particular period of time or in a given sample. |
|
Echolocation |
he location of objects by reflected sound, in particular that used by animals such as dolphins and bats. |
|
Infrasound |
sound waves with frequencies below the lower limit of human audibility. |
|
Ultrasound |
sound or other vibrations having an ultrasonic frequency, particularly as used in medical imaging. |
|
Sound |
vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear. |
|
Elasticity |
the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness. |
|
Acoustic |
relating to sound or the sense of hearing. |
|
Transducer |
a device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa. |
|
Tuning fork |
a two-pronged steel device used by musicians, which vibrates when struck to give a note of specific pitch. |
|
Compression |
the reduction in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition. |
|
Rarefaction |
is the reduction of an item's density, the opposite of compression. |
|
Cycle |
a series of events that are regularly repeated in the same order. |
|
Period |
As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. |
|
Amplitude |
the maximum extent of a vibration or oscillation, measured from the position of equilibrium. |
|
Wavelength |
the distance between successive crests of a wave, especially points in a sound wave |
|
Tone |
a musical or vocal sound with reference to its pitch, quality, and strength. |
|
Decibel |
a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale. |
|
Absorption |
the process or action by which one thing absorbs or is absorbed by another. |
|
Reflection |
the throwing back by a body or surface of light, heat, or sound without absorbing it. |
|
Refraction |
the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium |
|
Bitrate |
the number of bits per second that can be transmitted along a digital network. |
|
Codecs |
a device or program that compresses data to enable faster transmission and decompresses received data. |
|
Wrapper |
a piece of paper, plastic, or foil covering and protecting something sold. |
|
WAV |
is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. |
|
AIFF |
is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. |
|
CDA |
The CDA is designed for those individuals who are working with young children in all settings. |
|
MP3 |
a means of compressing a sound sequence into a very small file, to enable digital storage and transmission. |
|
AAC |
is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format |
|
MIDI |
a widely used standard for interconnecting electronic musical instruments and computers. |
|
Audacity |
the willingness to take bold risks. |
|
Garage band |
is single-channel. Typically there is only one microphone, one loudspeaker, or (in the case of headphones and multiple loudspeakers) channels are fed from a common signal path. |
|
Stereophonic sound |
This is usually achieved by using two or more independent audio channels through a configuration of two or more loudspeakers |
|
Surround sound |
a system of stereophonic sound involving three or more speakers surrounding the listener so as to create a more realistic effect. |
|
Streaming |
a method of transmitting or receiving data (especially video and audio material) over a computer network as a steady, continuous flow, allowing playback to proceed while subsequent data is being received. |
