Learning Objective
I can describe how the ear converts sound waves into signals the brain can understand.
- 1
The big flappy part of the ear, called the auricle, helps collect soundwaves and directs them into the auditory canal.
- 2
The middle ear amplifies soundwaves, and three tiny bones move the stronger signal to the inner ear.
- 3
Inside the cochlea, tiny hairs wiggle and send a signal to your brain, which helps you hear.
