COCHLEAR IMPLANTS
If there is no residual hearing left or total deafness is there, a cochlear implant can help you to get back a sense of sound. It is not the hearing aid, which makes sounds louder. It is the small device that a doctor puts in the ear through surgery. It works by transmitting impulses directly to the auditory nerve, which transmits sound signals to the brain.
it can assist you with all sorts of sounds. Most of the people with severe to profound hearing loss can understand speech conversations or over the phone reliably than they did with the hearing aid. It can frequently help you identify sounds around you, comprising telephones, doorbells, & alarms. Many people also may pick up on speech in noisy environments better than they did with listening aids, or even they can enjoy music again.
How does a cochlear implant work?
Cochlear implants are designed for children & adults with sensori neural hearing loss. This kind of hearing loss typically includes damage to tiny hair cells in the part of the inner ear called the cochlea. These hair cells pick up the vibrations of sounds &send them to the brain through the auditory nerve. When they are damaged, sound cannot reach the auditory nerve. A cochlear implant bypasses the damaged hair cells & sends signals to the hearing nerve directly.
Who should get a cochlear implant?
According to the Audiological Society, these devices are suitable for children and adults who have:
- Resolved to profound hearing loss in the both ears
- Hearing loss after they have already learned speech & language
- Inadequate help from hearing aids
- No medical difficulties that would make surgery risky
- A strong wish to be part of the hearing world
- A good knowledge of what the device will — and would not — do for them
