Q8. What is a cochlear implant?

A8. A cochlear implant is an electronic device which is able to stimulate the auditory nerve into transmitting electrical impulses to the brain. The brain interprets these impulses as sounds.

You cochlea contains millions of hair cells which help to pass sounds towards the brain via the auditory nerve. But if these are damaged or destroyed then this obstructs this process and leads to hearing loss.

A cochlear implant is comprised of several components which include electrodes (implanted into the cochlea), headpiece and microphone, speech processor (arranges sounds) and a receiver which converts sounds into electrical impulses.

This implant bypasses the damaged cochlea and sends signals through to the brain.
