induction loop system

induction loop system
= loop system
a device for helping people with some types of hearing aid or cochlear implant to hear more effectively in certain situations. Electrical signals from a television, sound system, or microphone are passed through an amplifier to a wire that is positioned in a loop encompassing the desired listening area. This creates an electromagnetic field that can be picked up by a coil within the hearing aid or cochlear implant. Induction loops are installed in such places as public buildings, lecture theatres, classrooms, and churches.
