How hearing aids work
Hearing aids work by enhancing the sounds around you to make them louder and clearer.
Hearing aids work by enhancing the sounds around you to make them louder and clearer. There are three main parts in a hearing aid – a microphone, amplifier, and speaker.
Sound waves are picked up by the microphone, which then converts them to electrical signals and then sends them on to the amplifier. The amplifier strengthens the signals and increases the volume.Find out more
Finally, the speaker converts the signals back to sound and passes it to the inner ear, and on to the brain where it will understand the sound.
Modern digital hearing aids are designed to identify and amplify speech rather than background noise. So with the right advice and prescription, most people find they can hear well again in most if not all situations.
