Induction loop systems are assistive listening devices designed to help people with hearing impairments. They consist of a loop of wire installed around a designated area, such as a room or a counter. When a sound source, like a microphone, is connected to the loop, it creates a magnetic field that can be picked up by hearing aids equipped with a telecoil. These systems are commonly used in public spaces, such as theaters, churches, and ticket counters, to improve sound clarity for users. By directly transmitting sound to hearing aids, induction loop systems reduce background noise and enhance the listening experience for individuals who rely on hearing aids.
