How Hearing Works
... The outer portion of the ear is cupped so it can capture the sound vibrations in the air. The vibrations travel through the outer ear canal and collide with the eardrum. This causes the eardrum to vibrate. Middle Ear The vibration of the eardrum moves the three small bones (called ossicles) in the m ...

Sound
In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.
