Hearing aids

A hearing aid is a small, sound amplifying device that you wear inside or behind your ear. It helps to make sounds clearer for people who have hearing loss. The World Health Organisation (WHO) estimates that 20% of the world’s population deals with a form of hearing loss. And it is estimated that only a fifth of these people act on their hearing loss and use hearing aids.

How does a hearing aid work?

A hearing aid works by increasing the level of sound that is delivered to the ear and sent to the brain for processing. A hearing aid consists of five core components, these are:

  • one or two microphones that pick up/sense sounds
  • a sound processor that makes speech clearer by reducing disturbing noise
  • an amplifier that makes soft sound audible
  • a small loudspeaker to present the processed sound to the ear
  • a rechargeable or disposable battery.

A hearing aid works through a straightforward process. The microphones pick up the sound, which is converted into electrical signals and sent to the sound processor. Sound is adjusted to increase the signal, i.e. speech, while reducing noise. The level of this signal is then increased by the amplifier and delivered to the ear via the loudspeaker.

Modern hearing aids make use of digital processing, and the most advanced ones make use of the latest technologies such as artificial intelligence (AI). Some hearing aids have rechargeable batteries, which is easy and convenient since there is no need to change or dispose of any batteries. More and more hearing aids can also be connected wirelessly to smart devices such as cell phones, music players, computers, and TVs.

What should I consider before I get hearing aids?

If you find yourself experiencing a decrease in your hearing capabilities, you may need hearing aids. The big decision to start wearing hearing aids and deal with your hearing loss can have a life-changing impact. Here are some things to consider before getting hearing aids.


If you start noticing signs of hearing loss, you should think about how your hearing has changed and when you have difficulties hearing. Where and when does it feel most affected, in what kind of an environment do you struggle to hear? This information can help your hearing care specialist tailor your hearing aids to the exact support you need. You can take our online hearing test as a first step and get an indication if you have a hearing loss.


A hearing aid compensates for the loss of sound sensitivity, making sounds and speech clearer and more comfortable for you in specific settings, but it will not bring your hearing back fully.


When you visit a hearing care specialist, they will go through the styles of hearing aids available and try to find the right one for your hearing needs and lifestyle. They will also guide you on the potential costs and available financial support to find a hearing aid that is both right for your hearing and financially sound.

How to adjust to life with hearing aids

Once you have chosen the hearing aid that best addresses your hearing loss, requirements, or budget, you will have it fitted by your hearing care specialist. They will offer you practical advice on how to wear your hearing aid correctly and how to use the accessories.

Although your hearing aid may provide an instant benefit, you will need time to adjust and become accustomed to amplification and the new experience of wearing something in and around your ear. The more you wear your hearing aid within different settings, the more likely you can get the best out of your hearing aid.

A few weeks or months after you start using your new hearing aid, it is advised that you organize a follow-up meeting with your hearing care specialist. You can ask any questions you might have. Furthermore, your specialist can check to make sure both you and your ear adapt well to your new hearing aid and adjust the hearing aid for the best hearing experience.
