How cochlear implants work

We design cochlear implants to replace the function of the inner ear that isn't working. Learn how implant systems process sound.

How cochlear implants produce clearer sound

Cochlear implants replace the function of damaged sensory hair cells inside the inner ear. Unlike hearing aids, which mostly make sounds louder, cochlear implants may further improve the clarity of sound and enhance your ability to understand conversations.

A cochlear implant system has two parts:

  • the external sound processor

  • the implant surgeons put under the skin and attach to an electrode array they place in the inner ear.

Together, the sound processor and implant bypass the part of the ear that isn’t working, sending sound straight to the hearing nerve. Watch the video below to learn more about how cochlear implants work.
