Cochlear implant refers to a device in which electrodes are inserted into the Cochlea to create hearing by electrically stimulating the auditory nerve fibers.

This device is used to restore hearing in people who have lost their hearing because of damaged hair cells. Moreover, Cochlear implant is a device surgically implanted in the Cochlea that allows a deaf individual to perceive sound by enabling sound to bypass damaged cells in the ear and directly stimulate the auditory nerve. Sound is picked up by an external microphone worn behind the ear, processed, and converted into electrical impulses, which are transmitted to an electrode array implanted in the Cochlea.
