Induction Loop Systems

Induction Loop Systems

Induction loop systems or  audio-frequency induction loops (AFILs) as they are also known by are a must have part of any audio and video system. They are required, where reasonably possible, under the Equality Act 2010 that replaced the Disability Discrimination Act 1995.

An induction loop system consists of a 'loop' of wire running around a specific area. This could be a whole room or smaller area, depending on the space that you want to be covered. The wire is attached to an amplifier which drives a current to generate a magnetic field that can be picked up by a hearing aid when set to the 'T' position. An audio signal is sent to the amplifier from an external device which can then be heard through the hearing aid when a person is standing within the area of the loop.

There are many different models and brands of induction loop amplifiers available so it can be daunting when you come to try and choose one. The main thing to consider is the length of cable that you will require as this will determine the type and strength of amplifier that you will need.

Induction loop systems have some drawbacks in that they can be quite difficult to install which means that you will probably need to bring in a professional. Some hearing aids do not have a coil fitted so they are unable to pick up the sound from an induction loop system and as technology advances further, induction loop systems may in fact become redundant. On a plus note however, the units themselves will have zero-rated VAT for churches and charities and require very little maintenance.  Once they have been set they can be left to run, only needing to be turned on and off!

These systems can sometimes cause interference with other equipment, however there are solutions to this which is another reason for you to have an induction loop professionally installed. They are however, a very cost effective alternative to infra-red systems, which although have positives in their own rights, they also have some drawbacks.
