What is a loop system and how does it work?
A loop system helps deaf people who use a hearing aid or loop listener to hear sounds more clearly by reducing or cutting out background noise. If you are at home, for example, a loop can be used to pick up sound from your television, hi-fi or radio. A loop can also be set up with a microphone to help hearing aid users hear conversations in noisy places. In the theatre, a loop can help you hear the show more clearly. An induction loop is a cable that circles the listening area. It is fed by current from a loop amplifier. The amplifier gets its signal from a microphone placed in front of the person speaking or by means of a direct connection from another sound source, such as a sound system. The resulting electric current in the loop produces a magnetic field, which corresponds to the sound. A deaf person wearing a hearing aid can then pick up this magnetic field if they are sitting within the area of the loop and their hearing aid – or loop listening aid – is switched to the “T” settin
