Profound hearing loss – Get your hearing back through cochlear implant

For those who have profound hearing loss, the world is silent. The cochlear nerve, also known as the auditory nerve is damaged beyond repair. The hair cells located in the cochlea responsible for the movement of impulses electrical brain are no longer viable. This resulted in a profoundly deaf people with this condition. Sometimes at any time before birth or after birth.

All is not lost. With the advent of advanced scientific technology, the cochlear implant can restore life to a boring existence. Those who do not can be heard on all finally be able to hear sounds that have lost the ability to hear or listen to the sounds that have never heard before.

The implant Cochlear is a hearing aid that is surgically implanted in the side of the head behind the ear in the temporal bone. There is an external part that fits around the ear and as a "Behind the ear (BTE) hearing aid. The device replaces the work of the damaged structures of the inner ear, sending a vibration through signals to the brain for interpretation.

How does a cochlear implant?

The cochlear implant device consists of internal parts and external. The outer part consists of:

microphone
battery
magnet
RF antenna transmitting sound
Computer processing

The computer converts the sound signals, sending the sounds of implanted inside the reception of sound. In the central part the receiver is called the receiver / stimulator, and includes a micro-computer, the antenna of the radio network magnet and electrodes. The magnets are of opposite polarity and hold the device outside the inner ring. Antennas, radio frequency that enables digital communication between the internal and external parties.

The sound is picked up by the microphone, that sends the sound to the speech processor (microcomputer). The sound is converted into signals sent to the transmitting antenna. The signals are sent to electrodes that encourage good cochlear nerve fibers. The signals are sent to the brain where they are interpreted by the brain into sound.

Cochlear implant does not restore hearing we know. What is to translate the sound into a signal that is sent to the brain. The brain translates the signal into information that can be recognized as the sounds of environment.

Age is important to be able to translate your product. Small children apparently have no problem doing so. The more a person is more There are difficulties in carrying out the translation. Intensive training is necessary, done by a professional qualified in the administration of this type of training.
