How we hear

Sound travels along the ear canal to the ear drum, which vibrates and transmits the sound to the middle ear.

Three tiny bones (ossicles) in the middle ear, the malleus (hammer), incus (anvil) and stapes (stirrup) pass the sound to the cochlea.

The cochlea is the small snail shaped organ of hearing which is filled with fluid and tiny hair cells which move in response to the vibrations.

As the hair cells move, small electrical signals are created, which are carried along the nerve of hearing to the brain, where they are interpreted as sound.

 

This video explain how we hear.

 

NDCS booklet 'Understanding your child's hearing tests' explains how the ear works, types of hearing loss and provides information about the different hearing tests.
