How Hearing Loop Systems Work
In the most basic form, an audio induction loop system consists of a loop of wire around the perimeter of an area that is connected to an induction loop amplifier. The wire creates a magnetic field within the perimeter so that the audio signals emitted from the amplifier can be picked up anywhere within the area by telecoil, a special receiver already built into most hearing aids.
If a hearing aid user switches their hearing aid to the telecoil (T) position, the telecoil converts the magnetic loop signal into sound. The magnetic field within the looped area is strong enough to allow a hearing aid user to move freely within the looped area and still receive clear sound at a comfortable listening level.
The input to the induction loop amplifier can be a sound source such as a television or stereo, a public address into a microphone, or any sound source that users inside the looped area wish to hear more clearly
Why use an Audio Induction Frequency Loop?
Increasing the sound volume in a person’s ears increases background noise. Because the neurological processing of information is often damaged with hearing loss, that background noise is difficult to filter out. With a Loop, the desired signal is taken straight from the basic source and transmitted directly into the hearing aid.Using the built-in T coil in the hearing aid means hearing aid user always has their “receiver” with them. Hearing Loop Systems are the most cost efficient assistive listening technology.
