HOW HEARING LOOPS WORK

A hearing loop system transmits an audio signal directly into a (Telecoil or, T-Coil equipped) 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:

Audio Inputs (1), either from an existing audio source such as a P.A. system or from dedicated microphone inputs feed an audio signal into an Induction Loop Driver (2). The driver produces a current into a Loop (3) or series of loops. As the current flows through the cable it creates a Magnetic Field (4) in the required area – careful loop and driver design ensures that the vertical component of the field is even and free of dropouts and dead zones wherever the user might be. Inside most Hearing Aids (5), a small coil known as a Telecoil (6) picks up the magnetic field signal, which is amplified into a high quality audio signal delivered directly to the ear of the hearing aid user.

Being hard of hearing in a hearing world can be quite challenging. Figuring out how to use the devices that help me hear can be complicated. Listen Technologies hearing loop provides a simple solution. No bulky devices to carry around or figure out. A simple switch to Tele-coil mode and I have access to reliable, clear sound.
