Hearing o-level

Hearing o-level

1. Sound funnels into the ear canal and causes the eardrum to move.
2. The eardrum vibrates with sound.
3. Sound vibrations move through the ossicles to the cochlea.
4. Sound vibrations cause the fluid in the cochlea to move.
5. Fluid movement causes the hair cells in Organ of Corti to distort.

Distortion of hair cells causes firing of impulses through Auditory nerves to the brain that interprets the nature of sound
