Hearing aids serve different purposes and needs. The goal of most hearing aid fittings is to make more speech sounds available to the listener. However, simply making sounds louder does not accomplish the goal! Most hearing aids process sounds to present specific speech information (sounds) to the listener, while reducing unwanted noises and sounds. In fact, with some hearing aid technology, such as; T-coils, FM systems, Directional Mics and Noise Reduction circuits, sometimes people wearing hearing aids can actually perceive a better speech signal than people not wearing hearing aids!
