A hearing aid is a valuable and sophisticated electronic device, so it's important to look after it carefully. Many people rely on their hearing aids every day to help them communicate with the people around them. However, hearing aids can't clean themselves or let you know when they need a little attention, so regular care and maintenance is essential to keep them working at their best.
When the performance of a hearing aid gradually declines due to factors like blocked microphones, earwax build up, a dead battery, moisture or component wear; the user may not immediately realise something is wrong. Hearing changes can be subtle and there's often no direct "before vs. after" comparison; which can make it very difficult for the user to identify.
