cochlear implant principles

A cochlear implant is a medical device designed to help people with severe hearing loss. Unlike hearing aids, which amplify sound, cochlear implants bypass damaged portions of the ear. They consist of two main parts: an external processor that captures sound and converts it into digital signals, and an internal implant that sends these signals directly to the auditory nerve. This stimulates the nerve, allowing the brain to perceive sound. While they don’t restore normal hearing, cochlear implants can significantly enhance the ability to understand speech and connect with the auditory world.
