The ear has three main parts
- Outer Ear
- Middle Ear
- Inner Ear
Each of these parts has a special function, that collectively allows us to hear.
Outer Ear
Sound is:
- picked up by the outer ear - pinna
- Sent down to ear canal to the eardrum and the middle ear
Middle Ear
As sound is sent down the canal to the eardrum
- Sound vibrations cause the eardrum to rock back and forth
- Three tiny bones in the middle ear send the sound vibrations to the inner ear.
Inner Ear
The inner ear contains over 30,000 tiny hair cells
- Vibrations from the middle ear cause these hair cells
- Hair cells are connected to the hearinf nerve and send the hearing signal to the brain.
A breakdown in any one of these three components can produce a hearing loss.
