Cochlear Implants
... Unlike hearing aids, which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain. A sound processor worn behind the ear or on the body, captures sound and turns it into digital code. The sound processor has a battery that ...
