How we Hear

This part of the ear is the fleshy attachment at the sides of our head and the ear canal which leads to the ear drum.

Sound is collected and reflected off the pinna walls and directed down the canal towards the eardrum.

This is the air-filled cavity behind the eardrum.  It contains the ossicles and is connected to the throat via the Eustahcian tube.

When the eardrum vibrates from sound, these tiny vibrations are transferred through the ossicles to the inner ear.

This section begins at the oval window, through the fluid filled Cochlea and on to the hearing nerve to the brain.

The mechanical vibrations at the oval window are converted into electrical impulses which are identified as sounds.
