A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin.
It is an electronic gadget that fits on the ear and is used to partially restore the hearing. This is very useful for people who are profoundly deaf and severely hearing problems due to inner damage. It has two parts one fits behind the ear and other is placed inside the ear through surgery. Unlike other hearing devices, cochlear implants pass sound signals to the auditory nerve by bypassing the damaged portions of the ear. The following parts consist of a cochlear implant:
- Microphone- Which grasp the sound from the environment.
- Speech processor-Which arranges the sound take-up by the microphone.
- Transmitter- This is used to receive the signal from the processor and convert them into an electrical signal.
- Electrode –This works to collect the electric signals and distribute them to a different region of the auditory nerve.

Cochlear implants are used to treat severe to profound cochlear hearing loss. Cochlear implants consist of a microphone and processor (usually located behind the ear), a transmitter (located on the skull behind the ear, usually held in place with a magnet), a receiver (implanted under the skin), and an array of electrodes in the cochlea.

Each electrode stimulates a different place in the cochlea, which corresponds to a different characteristic frequency. Sounds are processed by filtering into frequency channels; signals from each channel are used to stimulate different electrodes along the length of the electrode array. Similar noise reduction techniques can be employed as for hearing aids; the noise reduction occurs before the main cochlear implant processing.
What are the benefits of a Cochlear Implant?
Cochlear implant systems can offer a wide range of benefits including hearing speech, environmental sounds and music.
Nearly all cochlear implant users hear environmental sounds, keeping them in touch with their surroundings – including traffic, sirens, alarms, etc.
Virtually all recipients hear speech sounds through their cochlear implant. It usually takes some time to begin to understand these sounds, especially for children.
Hearing the speech of others as well as their own voice helps CI recipients to tune their speaking abilities.
Many people are able to use the CI system so effectively that they can understand speech without lip–reading and can have interactive conversations over mobile phones.
