What are Cochlear Implants?

Cochlear hearing implants have helped over 450,000 people hear. And no matter how many people we help, no matter how big that number gets, we still get choked up every time we see the priceless expression of someone being able to hear, either again or for the very first time.

Expectations with a Cochlear Implant


A cochlear implant will allow you to hear many sounds that you are not currently able to hear. This may be overwhelming at first. However:

  • With time and practice you will get used to hearing these new sounds


We expect you to be able to understand speech better after you get a cochlear implant. However:

  • A cochlear implant does not give you normal hearing
  • Even with a cochlear implant, it will always be easier to understand when you are looking at the person talking, especially if there is noise in the room.
  • We do not know how well you will be able to understand speech but expect that you will understand better than you can currently understand with your hearing aid(s)
  • Not everyone hears the same with a cochlear implant. For example, a person who has only had hearing loss a short time will usually hear better with a cochlear implant than someone who has been deaf for many years. Sometimes people hear differently with a cochlear implant and we don’t understand the reason.


We expect your speech understanding in noise to improve over time after you get a cochlear implant:


  • If there is noise in the room, you will always have more difficulty understanding speech than if the room is quiet. People with hearing loss often say they have trouble understanding when there is noise. This is true for people who use hearing aids and for people who use cochlear implants.
  • In an auditorium or a church/synagogue it may be more difficult for you to understand the speaker than if you were in a quiet room that was smaller and carpeted (e.g. a living room).
  • You may need to use assistive listening devices, like FM or infrared systems, in background noise or an auditorium type setting to improve your understanding.


Understanding the television should be easier with the cochlear implant than with your hearing aids. However:

  • Most people who have a cochlear implant and who used closed captioning before their implant still need some closed captioning after the implant to aid in understanding.
  • Television programs with background music/sounds may be very difficult to follow.
