A hearing loop is a wire that circles a room and is connected to a sound system. The loop transmits the sound electromagnetically. The electromagnetic signal is then picked up by the telecoil in the hearing aid or cochlear implant.
To use a hearing loop, you flip on the t-switch on the hearing aid or cochlear implant to activate the telecoil. Usually, no additional receiver or equipment is needed. Using a telecoil and hearing loop together is seamless, cost-effective, unobtrusive, and you don’t have to seek additional equipment. Hearing loops are also called audio-induction loops, audio loops, or loops. If your hearing aid doesn’t have a telecoil, you will need a headset plugged into a loop receiver to achieve the same effect.
