A reasonably standard definition of audible sound is that it is a pressure wave with frequency between 20 Hz and 20,000 Hz and with an intensity above the standard threshold of hearing. Since the ear is surrounded by air, or perhaps under water, the sound waves are constrained to be longitudinal waves.

Audible sound is produced by sound pressure applied to a listener’s ear. This pressure is initiated by a speaker or some other mechanical device that creates a series of pulses of energy that, in turn, cause air molecules to vibrate.

A vibration of your eardrum is responsible for the thing we call sound. For a human, the ear can only detect sounds that vibrate between 20 and 20,000 times per second. Vibration rates within these limits are audible.
