How Hearing Aids Work

Advanced digital technology has helped develop smaller and better hearing devices that are more comfortable than ever to wear. Some are so discreet that other people may not notice them. While they vary from manufacturer to model type, every hearing device has three elements in common:

  • Microphone that captures and converts sound into electronic signals,
  • An Amplifier that increases the electronic signal’s intensity (which makes sounds louder),
  • And a Speaker that converts these signals into a recognisable sound.


Each hearing aid also has a tiny, sophisticated computer chip. This allows the clinician to connect the hearing aid to specialised software and precisely tune the hearing aid to a prescription which will suit your individual hearing loss.
