The Physiology of the Senses
... Sound is produced when something vibrates, like the speaker in your stereo. When the speaker pushes on the air, it compresses it. The vibrating speaker produces a series of pressure waves that travel, at a speed faster than most jets, to the ear causing the eardrum to vibrate. But you do not hear th ...
