1. Hearing Impairment
By: Haleigh Baker

2. Hearing
1. Sound waves out in the air
travel to the pinna and enter
the ear
2. Sound waves travel
through the ear canal to the
middle of the ear.
3. Sound waves reach the
inner ear by the eardrum and
the ossicles
4. Sound waves are sent to
the auditory nerve and reach
the brain.
