How Does a Hearing Loop System Operate?
Hearing aids are incredibly effective at
improving a person’s ability to hear, but when
worn in a crowded atmosphere they can easily
overwhelm the wearer with unnecessary noise.
Concert halls, auditoriums, theaters, and
places of worship are particularly problematic
for the hard of hearing. Fortunately, hearing
loops systems provide a solution to this
disadvantage, allowing hearing aid users to
easily distinguish the sounds they wish to
focus on.
Hearing loop systems work together with the telecoil feature found in many hearing
aids. The original purpose of these telecoils was to work with the magnetic fields
created by telephone hardware. This allowed the wearer to easily listen to telephone
conversations without distraction from 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. This audio input is routed to a hearing loop amplifier,
which then feeds a current along a cable or series of cables that have been installed
around the room. If the technicians who install the hearing loop system do their jobs
correctly, anyone wearing a telecoil-equipped hearing aid will be able to hear the
transmitted sounds clearly wherever they are in the room, without any “drop-out” or
“dead spots”.
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.
Though no hearing technology is perfect, hearing loop systems offer a huge service to
many people, giving many listeners a much more enjoyable experience.
