GPS Installations specialize in the installation & maintenance of (AFILS) Audio Frequency Induction Loop Systems & Infra Red Hearing Systems.

How do Induction loop systems work?

An induction loop system transmits an audio signal directly into a hearing aid via a magnetic field, greatly reducing background noise, competing sounds, reverberation and other acoustic distortions that reduce clarity of sound.

This diagram illustrates how they work

In basic form, an induction loop system consists of a loop of wire around the edge of an area connected to an induction loop amplifier. The input of the amplifier is connected to the sound source that the hard of hearing users want to hear more clearly. The amplifier drives an audio current through the loop. This current generates a magnetic field in the area enclosed by the wire that a hearing aid switched to the T (Telecoil) setting can receive.

Infra Red Systems

Infra red audio systems are an alternative to induction loop systems. Using IR light based technology; audio signals can be radiated around a room or area to a recipient using a dedicated receiver. This receiver can be worn by any person regardless of their hearing capabilities in the form of a headset, or a hearing aid user may make use of a special receiver which connects to a small neck worn loop. This effectively provides them with a personal induction loop.
