What is an inductive loop system? Most people are familiar with hi-fi music systems. The sound source from radio, CD or cassette goes into an amplifier and is then fed out through the speakers. With a loop system, the sound source is usually TV, video, DVD or microphone which goes through the loop amplifier and then, instead of loudspeakers, the sound is fed into an induction loop. This loop is usually placed round the edge of a room - alternatively it could be smaller loop around an area such as a chair, or worn around the user's neck.
What is the advantage? A hearing aid microphone amplifies all the sound sources around the user which makes it very difficult for a hearing aid wearer to concentrate on one particular sound. Sometimes the only answer is to increase the volume on, say, the TV to such a point that it becomes very uncomfortable for anyone else. The induction loop allows a hearing aid user to listen to a single sound source with all background noise eliminated.
