Smart Bimodal Solution

If you're finding that your hearing aids are no longer enough, you may need to consider a more effective solution. To help you hear your best, you might consider getting a cochlear implant.

What is bimodal hearing?

If you have hearing loss in both ears and find yourself struggling with your hearing aids, there may come a time when you need a more effective solution. To improve your hearing performance and help you understand conversations more clearly, you might need to consider a solution that helps you hear your best with both ears.

A cochlear implant in one ear and continued use of a hearing aid in the other can provide enhanced hearing performance1. This combination is referred to as bimodal hearing.

Who can benefit from a bimodal solution?

A bimodal hearing solution can help people with a cochlear implant in one ear and enough hearing in the other ear to benefit from wearing a hearing aid.

The cochlear implant improves hearing in the ear where a hearing aid no longer benefits, and support is provided by the continued use of the hearing aid in the other ear.

Better hearing with a bimodal solution

Switching from a hearing aid to a cochlear implant offers a great leap in hearing performance2.

How do hearing aids and cochlear implants work together?

In a bimodal hearing solution, a hearing aid and a cochlear implant system work together to provide you with a richer and more natural hearing experience.

How bimodal hearing works

1. Cochlear implant system
provides clarity and crispness3

2. Your brain combines the signals
from both ears, resulting in a
clearer, richer and more natural
hearing experience

3. Hearing aids amplifies
sound to provide balance4

A bimodal hearing system can provide many benefits:

  • Greater clarity and improved speech understanding, especially in noise4, 5
  • Better determination of where sounds are coming from6.
  • Sounds are easier to hear and speech is easier to understand6, 7, 8.
  • Enjoy your favourite music again with better sound appreciation9.

These combined benefits help to build your speech and language understanding and is particularly beneficial for children's learning and development4.

What else should I know?

Bimodal hearing versus bilateral cochlear implants

When bimodal hearing is no longer enough or not an option due to the severity of your hearing loss, your hearing specialist may recommend two cochlear implants as another option. This is known as bilateral implantation. Your hearing health professional can help determine if bilateral implants are the best solution for your specific needs.
