What are the parts of a cochlear implant?
- Last Updated: Jan 28th, 2019
The cochlear implant is a device that provides a sense of sound to a person who is profoundly deaf or severely hard-of-hearing. It facilitates us to take the information through your auditory nerve. Though it needs the surgical procedure, the various components of the cochlear implant have unique functions and work together to make you hear. It replaces the function of the damaged inner ear.
Thus the parts of the cochlear implant enables the inner ear to perform its function smoothly. Let’s discuss each of the parts of the cochlear implant in detail.
Components of cochlear implant
A cochlear implant is an ear machine which is divided into the two parts which are as follows :
The external (outside) part which sits behind the ear and it consists of a microphone, a speech processor, and a transmitter.
An internal (surgically implanted) parts that work together to allow the user to recognize the sound. It contains receiver/stimulator and an electrode array.
Both of them work together to recognize the sound.
Let’s understand the working of the cochlear plant in detail.
Functions of the parts of the cochlear implants
Microphone – A microphone is a small component that is present behind the ear. It picks up the sound and sends them to a speech processor.
Speech Processor – It turns the sounds received by the microphone into a digital signal. It further sends the digital signal to a transmitter and it goes on your brain.
Transmitter – The transmitter sends the signal to a receiver under your skin. A magnet carries these two together.
Receiver – The receiver is present below the skin at the back of your ear. It sends the signals to electrodes in your inner ear to start stimulating the remaining nerve fibers.
Electrodes array – The electrodes trigger the auditory nerve throughout a portion of the cochlea. This lets your brain to recognize the incoming sounds and hence it produces a hearing sensation.
How Cochlear Implants help the people?
Cochlear Implants are designed for those who:-
- have balanced to profound hearing loss in both ears.
- Receive limited from hearing aids that will not help him.
- have not related to other medical problems that would make surgery risky.
- Is able to observe and speak.
- started to talk before they forfeit their hearing.
- will be able to get treatment to work on hearing skills
Benefits of a Cochlear Implants
- It hears more suitable with a cochlear implant than hearing aid.
- Helps to focus better when in noisy environments.
- It finds it easier to have conversations with people across meeting tables, in restaurants and any other crowded places.
- It reconnects with missed sounds that they could not identify before their cochlear implant.
- Feel safer in the world as they can identify alarms, people calling out and approaching vehicles.
- Enjoy tune or music.
Why it’s necessary
Increasingly, cochlear implants in both ears (bilateral) are popular as standard care for the treatment of severe hearing loss — particularly for infants and children who are learning to speak and to process language.
