What is an induction loop?
An induction loop is a cable that encloses the audience area. It connects to a loop amplifier that gets its signal from a microphone placed in front of the person speaking. It can also get a signal from a direct connection such as a sound system. The resulting electric current in the loop produces a magnetic field corresponding to the speaker’s voice.
Anyone within the area of the loop who is wearing a hearing aid switched to the ‘T’ setting, or a loop listening aid, can pick up sound from the loop. Users may need to adjust their own hearing aids for volume.
