What is sound - Shed The Music
... The ear is made of three parts; the outer ear, middle ear, and the inner ear. When sound comes through the outer ear (the part that you can see on your head) it is channel through the ear canal and comes in contact with the tympanum or eardrum. The tympanum vibrates with the areas of compression and ...

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.
