Traditionally, people resort to hearing aids in order to take care of their auditory problems. The perception of hearing reduces as age progresses and people find it absolutely necessary to come up with ways by which they can improve their hearing. However, cochlear implants have become extremely popular because of the method that it uses in comparison to the traditional methods of hearing aids.
What is a cochlear implant?
A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants bypass the damaged hair cells of the inner ear (cochlea) to provide sound signals to the brain.
Who can they help?
The cochlear implant technology can help people who:
Many people have cochlear devices in both ears (bilateral). Listening with two ears can improve your ability to identify the direction of the sound and separate the sounds you want to hear from those you don’t.

How is a cochlear implant different from a hearing aid?
A cochlear implant is very different from a hearing aid and is appropriate for individuals for whom hearing aids fail to provide benefit. A hearing aid makes sounds louder. Sound still travels through all the portions of the ear (outer ear, middle ear, inner ear) to the hearing nerve. A cochlear implant bypasses these structures and directly stimulates the hearing nerve with electrical energy. Because hearing aids amplify sounds and rely on the hearing system to convey the message, people with severe to profound hearing loss may be able to hear, but not understand speech well. The main objective of a cochlear implant is to improve speech understanding in quiet. Clarity with a cochlear implant is usually better than a hearing aid because the implant does not make sounds louder but delivers them to the hearing nerve.
There are a number of symptoms, which people should be looking out for before concluding that they have a hearing disorder:
