Explanation:
a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.
