How do we hear?

First, sound waves enter the outer ear and travel through a narrow passage way called the ear canal, which leads to the eardrum.

The incoming sound waves make the eardrum vibrate, and the vibrations travel to three tiny bones in the middle ear called the malleus, incus, and stapes—the Latin names for hammer, anvil, and stirrup. The middle-ear bones amplify the sound vibrations and send them to the cochlea, a fluid-filled structure shaped like a snail, in the inner ear. From the inner ear these sound waves are further traveled through auditory nerve to the brain for final perception of the sound.
