Question

The outer hair cells respond to sound by slightly tilting and changing length. because of the consequence of this, the action of the outer hair cells is called the _____.​

a. ​the cochlear amplifier
b. ​phase lock mechanism.
c. ​the tuning response
d. ​the traveling wave

Answer 1

The outer hair cells respond to sound by slightly tilting and changing length. because of the consequence of this, the action of the outer hair cells is called the cochlear amplifier.

This activity of outer hair cells can amplify the vibration so it's called cochlear amplifier. A disturbance in this mechanism can cause hearing loss.
