There has been a technological revolution in hearing aids

There’s been a revolution in hearing aids, thanks to a better understanding of how hearing works in the brain.

There has been a technological revolution in hearing aids. Recent research and insights have revealed why we need to think brain-first. See why this fundamental shift is key for your hearing health needs.

What do you want your hearing to be like?

It’s a question we seldom consider, but perhaps we should. After all, hearing is one of our major senses connecting us to the world.

We think hearing should be as natural as possible and free from constraints. It should work the way nature intended – even if you have a hearing loss and need hearing aids. In fact, especially if you need hearing aids.

Why your brain plays an important part in your hearing

We also believe the key to better hearing is in the brain. Hearing is thinking, after all! Our ears gather sound, but it’s in the brain that the sound is understood. In fact, the brain is our world’s best sound processor!

It makes sense then that your brain should get all the sounds around you. To get a sense of how important this is, consider the following example.

Imagine you are out walking

You are with your best friend in a park, chatting about the day’s events. All of a sudden, you see another friend to the right, and turn to say “Hi,” but your attention switches to the sound of running footsteps coming from behind you. Your brain tells you that a runner is about to pass, so you wait to approach your friend until the runner is well past you.

Now imagine you can’t hear the runner’s footsteps, so you can’t switch your attention to the sound. You would have crashed into each other and both of you would have probably been startled and confused.

Clearly, your brain works best if it gets the sounds all around you – just as nature intended.

This means good hearing aids shouldn’t simply make sounds loud enough. They should give your brain access to all the meaningful sounds around you and help it naturally understand the sounds you hear.

This brain-first approach to hearing aids is called BrainHearing™. And it’s a complete revolution from how the industry traditionally designs hearing aids.

The old way of making hearing aids

Hearing aids used to be made ear-first. This means they try to help by compensating for the hearing loss in the ear (increasing the volume).

But at times these amplified sounds might become too overwhelming, especially in noisy and crowded situations like cafés and family dinners. To address this challenge, traditional hearing aids may reduce some of the sound. Typically, they cut out the sound around you except for a narrow ‘beam’ of sound where you are looking – like tunnel vision for your hearing.

However, cutting out the other sounds around you may limit the information coming to your brain. And without all the information about the sound around you, your brain can’t work the way it is supposed to. Your attention is restricted or ‘blinkered’ – so you can’t hear things like footsteps behind you.

What’s more, whenever there are missing sounds, your brain may try to fill in the gaps by guessing. This is tiring, so it leaves your brain with less spare capacity for other things like remembering and makes socialising harder (i) – and socialising is vital to your brain’s health!

Brain-friendly hearing aids are the answer

The good news is that we now know better, and thanks to hearing aid manufacturer Oticon, brain-friendly hearing aids are available.

We now know that your brain needs access to all meaningful sounds – not just speech – in order to work in a natural way. (ii)

Then, when your brain has all the information it needs, it can naturally orient itself and choose what to focus on.

This is the way the brain naturally makes sense of sound, so this is what brain-friendly hearing aids are designed to help your brain do.

The results are impressive. Brain-friendly hearing aids can reduce listening effort and provide a natural, pleasant, and balanced soundscape, instead of simply amplifying individual sound sources, such as only the person talking in front of you.
