Cochlear implants are tiny electronic devices, which electronically stimulate the cochlear nerve. The electronic device has internal and external components. The internal part sits just above the ear on top of the head. It picks up external sounds using a microphone attached to a generator, which is located inside your inner ear.
Cochlear implants are very effective in management of hearing loss and tinnitus. One in eight people in the U.S. aged 12 years or older has hearing loss in both ears. Tinnitus is a condition which causes sound signals within the ears to vary. This condition can be a serious cause of hearing impairment for those who have it and are unable to adjust their sound signals to regular environments. Cochlear implants help people suffering from this condition because they actually stimulate the nerve endings in the inner ear, thus rewiring the cochlea to work better.
As soon as the buzzing sound starts, the implant stimulates the nerves inside the inner ear, which in turn produces the electrical signals necessary to hear. You can get Cochlear implants for different purposes. You can use them to treat mild deafness which is caused by wax build-up in the auditory canal. Some individuals have trouble hearing the sound produced by other people, if there is sound interference. This problem can be remedied by placing the electronic device behind your ears. Thus, they can be placed near the eardrum.
The cochlear implant can also be used to treat people with hearing loss caused by genetic predisposition. Some people may suffer from a condition called sensorineural hearing loss which is caused by their inner ear having problems. This kind of condition usually has no permanent cure. Thus, the doctor who performs cochlear implant surgeries can help people with this condition by providing them with small electronic devices to help them to understand speech. Sometimes, people use hearing aids to help them communicate with others. If you are going to use an electronic device to make sounds like a telephone, you will need a hearing aid.
