A cochlear implant is an electronic
device that is used to produce hearing in damaged inner ear. Unlike hearing
aids, which make sounds louder, cochlear implants do the work of damaged parts
of the inner ear (cochlea) to provide sound signals to the brain.
Cochlear implants are invented to cure
severally damaged and children who get little or no benefit from hearing aids.
Even individuals with severe or profound "nerve deafness" may be able
to benefit from cochlear implants.
A cochlear
implant takes sounds from the outer area and then converts it and send it near
to auditory nerve.These electric currents activate the nerve, which then sends
a signal to the brain. The brain learns to recognize this signal and the person
experiences this as "hearing".
The cochlear
implant makes a situation of natural hearing where current is created by sound
that stimulates the auditory nerves. However, the result is not the same as
normal hearing.
