Induction Loops supplied and installed from Technical Services Shropshire

As from October 2004 the final phase of the Disability Discrimination Act (DDA) enforced any organisation that provides services to the public to treat disabled people – whether customers or staff – less favourably than others for reasons related to their disability illegal. Hearing impairment is a recognised disability under the DDA.

At Technical Services we can provide auxiliary aids to satisfy the legislation and provide a less daunting, more welcome environment for the hard of hearing.

What version are Available ?

Our Hard of hearing systems are available in the traditional induction loop form, Portable desk type over the counter or a secure infrared system.

What are the advantages?

Hearing loss often not only results in an inability to hear at a distance, but also impairs the ability to isolate what you want to hear from the background noises. In a typical church these would include the rustling of hymn book pages, people coughing, children crying, et cetera. The hearing impaired person will often find these nearby noises completely mask the person speaking through a public address system.

Who does it help?

Those with a hearing aid that has a T position can make use of the loop system. This position switches the hearing aid microphone off, and the pick-up coils on.

What about the rest who may benefit?

Induction Loop Receivers are a compact sub-walkman sized unit with walkman style headphones. People without hearing aids may find listening on the loop an improvement for them. In addition the receiver can help the sound system operator double check that the loop system is operational.

Where is the Loop installed?

The cable will generally run either at floor level, or at approximately two metres above seated head height. This ensures that the signal in the users hearing aid remains constant across the area covered. The cable is a thin one, similar in size to domestic telephone cable, and is installed in a discreet manner around the room.

Diagram of an Induction LoopHow does an induction loop work?

An induction loop system basically comprises of a microphone, an amplifier and a loop aerial.

The sound picked up through the microphone is converted by the amplifier into magnetic impulses. The impulses are transmitted via the loop aerial and received by the telecoil within the hearing aid.

The Loop aerial is traditionally installed around the area to create a loop

The wearer of hearing aid has to have it set to “T” and within proximity of the loop aerial.

What about Audio Security?

A loop system radiates the signal both inside and outside the loop. These impluses transmitted through the loop can sometimes broadcast through the neighbouring wall, this is known as overspill.

For most applications (churches, etcetera) the overspill is not a problem.

However for sensitive situations such as court rooms & coucil chambers, the loop cable can be laid under the floor covering in a pattern to reduce the overspill to an acceptable level. If this is felt to be insufficient, then an alternative such as infra-red needs to be used.
