Hearing loop systems work with the telecoil feature in many hearing aids to provide accessibility. They create magnetic fields that transmit audio signals to hearing aids without background noise. The audio signal travels to a loop amplifier and then through cables looped around a venue. Anyone with a telecoil in their hearing aid can then listen to the audio signal without needing additional equipment. Hearing loop systems offer a discreet listening experience for those with hearing aids and help make venues accessible.

How a Hearing Loop System Works
When a hearing aid wearer attempts to listen to
a speaker in a crowded area, the levels of
background noise can quickly become daunting.
This is especially true in noisy venues such as
movie theaters, concert halls, auditoriums and
churches. Hearing loop systems offer a simple
solution to this issue, making it very easy for
people with hearing aids to enjoy sermons,
movies, concerts, and other oral presentations
without distraction.
Hearing loop systems work together with the telecoil feature found in many hearing
aids. Telecoils were originally designed to pick up on the magnetic fields created by
coils within telephones. By isolating these fields, telecoils allowed people wearing
hearing aids to have clear phone conversations without being annoyed by background
noise. These same telecoils can be used by today’s hearing loop systems, which
create magnetic fields on a much larger scale.
The first part of a hearing loop system is an audio input, often from a PA system or a
dedicated microphone feed. The input travels into a hearing loop amplifier, which
then drives a current through one or several cables that are looped around the
venue. Properly installed loops do not have dead zones, which mean that anyone with
a telecoil who is inside the loop can pick up on the transmitted audio.
While newer technology such as FM transmission neck loops are becoming more
established among many establishments, hearing loop systems can still offer a
number of advantages to the hard of hearing. These systems are very convenient for
patrons, whose hearing aids have a telecoil feature, allowing them to visit any
properly equipped venue without worrying about their ability to hear. They also
provide a simpler, more discreet listening experience, since they don’t require the
user to wear any additional equipment.

While hearing loop systems require some initial investment in terms of equipment
and set-up, they are a proven way for venue owners and managers to offer a high-
quality listening experience to as many visitors as possible.
