What does a cochlear implant do?

A cochlear implant functions by converting sounds into electrical signals, which is crucial for individuals with severe hearing loss or profound deafness. This device bypasses damaged portions of the ear and directly stimulates the auditory nerve.

Once a person with hearing difficulties receives a cochlear implant, the microphone catches the surrounding sounds and sends them to a processor. The processor converts these sounds into signals that the implant can then use to stimulate the auditory nerve fibers. This process allows the brain to interpret the sounds as recognizable speech and other auditory information.

This distinct function differentiates cochlear implants from other auditory devices, such as hearing aids, which merely amplify sound vibrations. Cochlear implants do not redirect sounds to the outer ear nor do they filter background noise in the same manner that some advanced hearing aids might. This unique operation makes cochlear implants an innovative solution for providing a sense of sound to those who cannot benefit from conventional hearing assistance.
