What is a Hearing Loop?
The loop systemAn audio frequency induction loop (hearing loop) system gets its name from the configuration of an installed system, which is, in its simplest form, a wire surrounding (looping) a room usually in or under the floor. Both ends of the wire that is looped around the room are plugged into a special type of amplifier, and the amplifier is connected to an audio source. The audio source can be the venue system or simply a microphone. The amplifier sends the sound as an electric current through the loop wire. The electric current in the loop wire transmits a signal that can be received by a hearing instrument in the room.
The hearing instrumentInside most hearing instruments (hearing aids or cochlear implants) is a tiny coil of copper wire called a telecoil or T-coil. The T-coil receives the signal transmitted from the loop wire. If the user of the hearing instrument switches the instrument’s input mode from "M" (for microphone) to "T" (for T-coil), then the hearing instrument receives the signal from the loop wire and converts it into clear comfortable sound for the user. When in T-coil mode, the user has a direct, clear, wireless connection with the venue sound system and does not hear distracting, surrounding noises.
For someone with hearing loss but no hearing aid, a loop receiver with headphones or earbuds provides the user with clear sound from the loop.
SummaryIn summary, the hearing loop is the system (the amplifier and loop wire) installed in a venue. The hearing loop transmits directly to the T-coil that is built inside most hearing aids and cochlear implants providing clear comfortable sound -- without background noise -- to the user of the hearing instrument.
