How A Hearing Loop Works

A hearing loop provides a magnetic, wireless signal that is picked up by the hearing aid when it is set to „T‟ (Telecoil) setting. The loop system consists of a microphone to pick up the spoken word; an amplifier which processes the signal which is then sent through the final piece; the loop cable, a wire placed around the perimeter of a room or sanctuary to act as an antenna that radiates the magnetic signal to the hearing aid. When a hearing aid user selects the „T‟ setting; he or she can pick up the sounds spoken into the PA system‟s microphone instead of the hearing aid‟s internal microphone. This results in improved speech understanding because the listener receives a clear signal without any background noise.
