They are the outer ear (the part we see along the sides of our head behind the temples), the middle ear, and the inner ear.

The external ear helps concentrate the vibrations of air on the ear drum and make it vibrate. These vibrations are transmitted by a chain of little bones in the middle ear to the inner ear. There they stimulate the fibers of the auditory nerve to transmit impulses to the brain.
