The ear is made up of three different sections: the outer ear, the middle ear, and the inner ear. These parts all work together so you can hear and process sounds.
VIDEO to explain how the ear works.

HOW THE EAR WORKS
A sound wave comes in from the outside. It is collected by the pinna and enters the ear canal.
After it passes through the outer ear the sound waves strike the ear drum.
Then, the sound waves hit the ear drum and make it vibrate. This vibration moves the hammer, then the anvil and finally the stirrup.
Then the stirrup moves and pushes against the cochlea.
In the cochlea, sound moves as a wave creating vibrations.
The cochlea contains fine hairs that are moved by the sound waves. This movement of the hairs causes electrical impulses that travel up the auditory nerve to the brain.
The brain makes sense of the signals and tells us what we can hear.
