The microphone picks up sound waves and the processor converts them to electrical impulses, which are transmitted by the external coil through the skin to the internal coil and then to the electrodes. The electrodes stimulate the auditory nerve. A cochlear implant doesn't transmit sounds as well as a normal cochlea but provides different benefits to different people. It helps some people read lips. Others can distinguish some words without reading lips.
Some people can hear on the telephone.
It helps them modulate their own voices to make their speech easier for others to understand. A cochlear implant is more effective in a person whose hearing loss is recent or who had successfully used a hearing aid before the implant. All rights reserved.
