(acoustics) a wave that transmits sound
Source: WordNetWorking in the digital domain, you're using approximations of things; the actual sound wave never enters the equation. You deal with sections of it, and you're able to do so much more by just reducing the information to a finite amount. Sean Booth
Acoustic interferometry An acoustic interferometer is an instrument for measuring the physical characteristics of sound wave in a gas or liquid. Source: Internet
Acoustics looks first at the pressure levels and frequencies in the sound wave and how the wave interacts with the environment. Source: Internet
Electret microphones and condenser microphones employ electrostatics—as the sound wave strikes the microphone's diaphragm, it moves and induces a voltage change. Source: Internet
