How does a cochlear implant work

A cochlear implant creates a new way of hearing. It consists of an internal implant which is surgically inserted into the inner ear, and the external sound processor that is worn on the ear or the body.

How the basic parts of a cochlear implant work:

  1. The microphone captures sound waves that pass through the air.
  2. The sound waves are converted into detailed digital information by the sound processor.
  3. The headpiece sends the digital signals to the cochlear implant and electrode array in the inner ear.
  4. The electrode array stimulates the hearing nerve.
  5. The hearing nerve sends impulses to the brain, where they are interpreted as sound.
