cochlear implant

 
a device consisting of a microphone, signal processor, external transmitter, and implanted receiver; the receiver is surgically implanted under the skin near the mastoid process above and behind the ear. It is an alternative to total deafness, although it does not actually restore hearing. Deaf persons using the implant do not hear sounds in the same way hearing persons do, but they can be taught to interpret sounds transmitted by the device.

co·chle·ar im·plant

an electronic device consisting of a microphone, speech processor, and electrodes that are implanted in the inner ear to stimulate the remaining nerve fibers of the auditory division of the eighth cranial nerve in adults and children with profound hearing impairment or deafness. Many recipients of cochlear implants achieve high, open-set word recognition and can understand speech even over the telephone.

cochlear implant

n.
An electronic apparatus that allows people with severe hearing loss to recognize some sounds, especially speech sounds, and that consists chiefly of a microphone and receiver, a processor that converts speech into electronic signals, and an array of electrodes that transmit the signals to the cochlear nerve in the inner ear.

cochlear implant

an electronic device that is surgically implanted into the cochlea of a deaf individual. A transmitter placed outside the scalp sends signals to a receiver under the scalp, which in turn transmits an electrical code to the auditory nerve. A microphone is located behind the ear to collect the sound waves that are transmitted through a microprocessor. The microprocessor analyzes the sound waves and relays data back to electrodes in the implanted device. The patient receives electrical pulses that are translated into sound vibrations that can be distinguished as neural sensations. Although the implant does not transmit speech in the same manner as it would be perceived by a person with normal hearing, it allows the individual to perceive and distinguish sounds that would not otherwise be audible to him or her and to use those sounds along with other environmental cues to improve communication. Also called cochlear prosthesis.

Audiology A multicomponent electronic prosthetic device for those with severe hearing loss, whose sensory neurons have been damaged, but not completely destroyed, and for whom conventional hearing aids are inadequate; CIs bypass damaged structures in the inner ear and directly stimulate the auditory nerve.

cochlear implant

A device designed to stimulate the acoustic nerve so as to produce some form of hearing in people wholly deaf from inner ear disease. Although there have been great advances in multichannel implants, the results still cannot be said to compare with natural hearing. But cochlear implants can make a substantial difference to children born deaf or becoming totally deaf before 3 years of age, so long as the implant is inserted before the age of five. Most of the children who receive such implants are able to develop intelligible speech.
