How we Hear
![]() |
The Outer Ear |
||
Location: | 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: | Sound is collected and reflected off the pinna walls and directed down the canal towards the eardrum. |
|
The Middle Ear |
||
Location: | This is the air-filled cavity behind the eardrum. It contains the ossicles and is connected to the throat via the Eustahcian tube. |
![]() |
Sound: | When the eardrum vibrates from sound, these tiny vibrations are transferred through the ossicles to the inner ear. |
|
Inner Ear |
||
Location: | This section begins at the oval window, through the fluid filled Cochlea and on to the hearing nerve to the brain. |
![]() |
Sound: | The mechanical vibrations at the oval window are converted into electrical impulses which are identified as sounds. |
