What Is a Cochlear Implant?
A cochlear implant is a small electronic device that helps those who are profoundly deaf or have severe hearing loss to interpret sounds and understand speech. They do not restore hearing, nor do they work in the same manner as hearing aids do.
The implant provides a sense of sound to a person through internal and external parts that work together to bypass damaged portions of the ear and directly stimulate the auditory nerve. The signals made by the implant are sent to the brain, which then interprets the sound.
