cochlear implant is a medical device that is implanted into
the head behind the ear of a deaf person. When used with
a microphone and speech processor it electrically stimulates
the auditory nerve and results in the person being able
to hear sound. When the system was first developed in 1978
by Graeme Clark it was referred to as the bionic ear. Since
that time a variety of cochlear implants have been developed
by the Cochlear division of Nucleus.
Limited was founded in Australia in 1981 and, since then,
has maintained its position as the international leader
in the manufacture and sale of Nucleus® cochlear implant
systems. (Cochlear, 2000: 2)
implants are designed for use by adults and children who
are profoundly or severely deaf and get little or no help
from hearing aids.
Nucleus implant systems enable hearing impaired people to
perceive most environmental sounds and speech. The number
of Nucleus® implant recipients worldwide has grown to
over 27,000, with more than 13,000 of these being children.
(Cochlear, 2000: 2)
cochlear implant is an example of innovations in design,
combined with engineering, information processing and software
design and development.
