SOUND DEFINITIONS
Amplitude (Volume): The maximum extent of a vibration or oscillation, measured from the position of equilibrium.
Frequency (Pitch): The rate at which a vibration occurs that constitute a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light).
Sound Wave: A wave of compression and rare fraction, by which sound is propagated in an elastic medium such as air.
Speed of Sound:The speed of sound is the distance traveled during a unit of time in dry air at 20 degrees Celsius, the speed of sound is 343.2 meters per second.
Subsonic: Relating to or flying at a speed or speeds less than that of sound.
Supersonic: Evolving or denoting a speed greater than that of sound.
Wavelengths: The difference between successive crests of a wave, esp. points in a sound wave or electromagnetic wave.
