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 enable 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.
