A cochlear implant is usually turned on 1 to 4 weeks after surgery. At first, voices often sound like robots or beeps. That is normal. Most people keep getting better for 3 to 12 months. Here is what happens, step by step.

The first year, step by step
- Surgery. A short operation. You often go home the same day or the next day. The implant stays off while you heal.
- Switch-on, 1 to 4 weeks later. An audiologist turns it on and sets it up. You hear sound straight away, but words may not be clear yet.
- The first 3 months. A few visits to fine-tune it. This is when most people notice the biggest change.
- About 6 months. A check-up. Many people can talk on the phone with family by now.
- About 12 months. A bigger check-up. After this, usually once a year.
Our honest advice: the first few weeks can feel strange
Some people feel let down at switch-on because voices sound funny. That does not mean it is not working. Your brain is just learning something new. People who have been deaf for a very long time usually take longer, and may not get as much benefit. We would rather tell you that now than have you surprised later.
What helps the most
- Wear it all day. Your brain learns by listening a lot.
- Practise every day. Audiobooks while reading along, TV with captions, phone calls with family.
- Go to every check-up. Small changes early on make a big difference.
- Say what is hard. Noisy cafes, music, the phone. Your audiologist can work on it.
- Bring your family. They can practise with you and learn to speak clearly, not loudly.

Frequently asked questions
When is a cochlear implant turned on?
Usually 1 to 4 weeks after surgery, once you have healed. This is called switch-on. An audiologist connects the outside part and sets it up for you.
What does a cochlear implant sound like at first?
Often like robots, beeps or cartoon voices. That is normal. Your brain is learning a brand new way to hear. For most people, voices sound more normal after a few weeks or months.
How long does it take to get used to a cochlear implant?
Most grown-ups keep getting better for 3 to 12 months. Lots of people notice the biggest change in the first 3 months.
How many check-ups will I need?
A few in the first 3 months to fine-tune it. Then check-ups at about 6 months and 12 months. After that, usually once a year.
How can I get used to it faster?
Wear it all day, every day. Practise listening, like audiobooks while reading the book, or phone calls with family. Go to every check-up and say what is hard.
