What are Induction Loops? Induction loop systems help hearing impaired people who use a hearing aid or loop listener to hear sounds more clearly by reducing or cutting out background noise. 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. You can then pick up this magnetic field if you are sitting within the area of the loop and your hearing aid - or loop listening aid - is switched to 'T'. You will need to adjust your own hearing aid for volume. More than one person can benefit from a loop installed in a room as long as they each have a hearing aid set to 'T', or a loop listener. You are not wired to any other equipment and you are therefore free to listen from anywhere within the loop and to move around.
