As I gave a note in my previous blog that hearing aid after many yrs causes severe headaches and finally the person using it permanently stops hearing.
For this the device called “Cochlear implant” is used now -a -days.A cochlear implant is a small, complex electronic device that can helps to provide sense of sound to the person who is deaf frm birth or have some hearing problems.
Cochlear implant is very different from hearing aid. Hearing aid amplifies the sound while this device bypass the damaged portion of our hearing sense n directly stimulate the nerves.
It can help people with sensoryneural hearing loss more. A tiny mic which is worn behind d ears filters d noise and clear speech is produced. This signal is electromagneticall sent to Rx & stimulator which is implantd in skin and r converted into electrical pulses sent to the brain.
