As activation (switch-on) of your new sound processor approaches, you'll probably feel nervous and excited.

To help you prepare, here's a list of questions you may want to ask your audiologist to understand what you or your child may expect on switch-on day and beyond.

  1. What happens during the appointment?
  2. What does activation of the cochlear implant feel like?
  3. Will I hear right away?
  4. How will it sound? Will it sound just like I remembered, or will it sound mechanical or high pitched?
  5. How long will it take to adjust to the new sound?
  6. How do I put on my sound processor?
  7. How does my device work?
  8. Do you have any tips for using my new sound processor?
  9. How often will I need to charge/change the batteries?
  10. Can I go swimming/take a shower right away?
  11. How do I store/care for my device?
  12. What resources and activities do you recommend for rehabilitation?
  13. What happens if my hearing changes over time?
  14. How often will I have to fine tune and adjust my sound processor's programs.
  15. Is there a network of hearing implant recipients in our community? Can you put me in touch with them?

What usually happens on activation day?

Your audiologist will explain how your sound processor works and how to care for it. They will program your sound processor and set the volume and pitch levels that are right for you.

It may feel like this is taking a long time, but it's normal. This process is called mapping.

The aim of this appointment is for you to tell the difference between a loud or soft sound. If you can tell the difference, you're on your way.

Don't worry if you can't hear clearly right away. It may take days or weeks of practice to train your brain to understand the signals it's receiving.

You may be lucky enough to enjoy an activation moment like Sangeeta.

“When my son called me ‘Mummy’ I felt so good. I used to feel sad that I couldn’t hear that word from my children. I almost forgot how it sounds like…it feels great.”

- Sangeeta J, Cochlear™ Kanso® implant recipient, India

After your sound processor is switched on

Over the next several months, you will probably have some appointments with your audiologist. This is to fine tune the programs on your sound processor and help you get the best possible results from your new hearing — such as how accessories can help you when using the phone or listening to music.

You will need to follow the guidelines on how to maintain your device. To help, we offer many "how to" videos and our customer service team can answer your questions.

Rehabilitation is vital to your hearing progress and success. You will need to practise listening and speaking as much as possible to ensure the best outcomes post switch-on.

Practise and patience

Keep in mind that progress may take time, so persistence and consistency is a great help. Everyone's hearing is unique. While some can hear well after one or two mappings, others take longer.

Practise and patience helps your brain to learn how to interpret the sounds. That's why we offer easy-to-use rehabilitation programs we can tailor to your needs at every learning level.
