Is it time to consider a hearing implant?

Do you have difficulty hearing on the phone or understanding conversations? Perhaps you no longer participate in the activities you once enjoyed because of your hearing loss. Whether you lost your hearing suddenly or gradually over time, a hearing implant can help you reconnect with the people and activities you love.

When hearing aids aren’t enough

If hearing aids are no longer helping you, or you have stopped wearing them altogether, a hearing device such as a cochlear implant or bone conduction implant, may be able to help. Some common signs that hearing aids are no longer providing enough benefit include:

  • Having difficulty hearing conversations, especially in background noise.
  • Having trouble hearing the TV or talking on the phone.
  • Frequently asking people to repeat themselves or misunderstanding what they say.

Getting your hearing checked is the first step towards finding a hearing solution that may improve your hearing and quality of life.

Clearer hearing, clearer thinking

The effects of hearing loss go beyond sound. It’s been linked to changes in memory, focus and thinking skills.1,2

Studies have shown that cochlear implant users have improvements in memory and thinking after one year. 2,3 Clearer hearing can help reduce the mental effort of listening, supporting memory and focus.

The difference between hearing aids and hearing implants

Hearing aids help people with hearing loss by amplifying sounds. As hearing loss progresses, sounds may need to be clearer, not just louder. When hearing aids are no longer providing enough benefit, hearing implants may offer an alternative treatment option for certain types and degrees of hearing loss.

"Recently I went to the Pink concert...I changed my Osia to the music setting on my phone so I could hear the sound better. It was like listening to it in full stereo...It wasn’t an echo or anything. I could hear every pitch, every beat, every sound that came our of her mouth...I was part of the concert."

How much does a hearing implant cost?

There are different funding options available for candidates in Australia and New Zealand, which may cover the costs of cochlear implants in full.

How do I get a hearing implant?

If you decide to go ahead with a cochlear implant, the process will comprise several steps, from initial assessment to rehabilitation. Knowing what to expect at each stage will help you feel prepared and confident.

  1. Talk to your audiologist
    Ask about the possibility of a cochlear implant. Your audiologist will be able to determine whether you could benefit from one and refer you to a specialist clinic for an assessment if necessary.
  2. Assessment
    An assessment is an opportunity to talk to healthcare professionals and ask lots of questions. It will involve a variety of tests over several appointments.
  3. Surgery
    The surgery itself is typically a routine outpatient procedure lasting two to four hours under general anaesthesia.
  4. Activation
    A few weeks after surgery, your audiologist will activate your cochlear implant sound processor. This is when you begin hearing through your implant.
  5. Rehabilitation
    You’ll be supported by audiologists and therapists over the following months, learning to embrace your new world of sound with regular speech and listening practice.

Frequently asked questions

Hearing implants are proven to be a successful solution for people in their 80s and 90s. It's never too late to regain access to the sounds you're missing.

 

No, hearing implant surgery does not involve the brain. The surgeon makes a small incision behind the ear and places the implant underneath the skin. In most cases, you can return home on the same day and can get back to your normal activities within a few days.

Learn more about surgery and preparation.

 

No, you don't have to be completely deaf to get a hearing implant. If you start struggling to hear and understand speech even with powerful hearing aids in noisy environments, talk to your audiologist about hearing implants.

 

Benefits of a hearing implant

"The quality of the sound for me is very crisp, very clear. I’ve never known anything like it. Just to be able to walk along and actually enjoy the wind blowing through the trees. It puts a smile on your face because you’re actually then realising what you’ve missed.” *
