What is a Cochlear Implant?
A Cochlear Implant is a highly sophisticated device, which provides access to sound for people with severe to profound hearing loss. The surgically implanted device, when coupled to an external processor, can provide access to speech and everyday sounds to aid or improve communication abilities. A cochlear implant is an electronic device that restores partial hearing to the properly selected deaf. It is surgically implanted in the inner ear and activated by a device worn behind the ear. Unlike a traditional hearing aid, which simply amplifies sound which is then heard in the normal way, a cochlear implant converts sound to electrical impulses which are then transmitted to the nerve of hearing that would normally carry the auditory signal to the brain. The device bypasses damaged parts of the auditory system and directly stimulates the nerve of hearing, allowing individuals who are profoundly hearing impaired to receive sound. Presently, cochlear implant is the only hope for these groups of patients for developing and learning linguistic ability for communication. Cochlear implant is now an accepted and established method of therapy for deafness in children and adults.
