Question

How does a cochlear implant work?

Answer 1

The cochlear implant has two parts.

Explanation:

There's the cochlear implant which is attached to the head, and there's the speech processor which is around the ear. When there is sound, the microphones on the speech processor turn these sounds into signals which go to the transmitter. The transmitter sends these signals to the internal implant (so from the external device attached to the side of the head to the implant INSIDE), which turn these signals into electrical energy being sent to an array of electrodes. This allows the nerve fibers in the cochlea to react, making the brain to perceive this as sound.

I have a deaf friend who has a cochlear implant. :)

Hope this helps!
