What is a hearing aid?
Hearing aids are small, high-tech devices that help you hear if you suffer from hearing loss. They amplify your surrounding sounds (such as conversations, TV shows, or the radio) to help you communicate and participate in everyday situations.

How does a hearing aid work?
Sound is carried across three different components:
- Sound enters the hearing aid through a microphone.
A microphone, set within the small hearing aid that you wear in your ear, picks up sounds around you.
- Sound is processed and amplified.
Sounds are then analysed via the processing chip in the hearing aid, and processed sounds are sent to the amplifier.
- Sound is delivered to a receiver.
Amplified sounds are sent to the loudspeaker inside the hearing aid device, which then transmits sounds into the inner ear where they are transformed into electrical impulses. The brain receives these electrical impulses and processes them to create audible sounds.
