Acoustic waves are a type of energy propagation through a medium by means of adiabatic loading and unloading.
Longitudinal wave that propagates by means of adiabatic compression and decompression;travels with the speed of sound which depends on the medium they're passing through
The travelling of acoustic waves in the atmosphere with a speed independent of their amplitude. The speed only depends on the acoustic medium and is proportional to the square root of the absolute temperature for any given medium.
Auditory sensation produced by the oscillations, stress, pressure, particle displacement, and particle velocity in a medium with internal forces; pressure variation that the human ear can detect.
The longitudinal wave of pressure that is transmitted through any plastic material; audible sound.
