Induction Hearing System

Induction Loop Systems

Induction loops for the hard of hearing are now becoming mandatory in many public buildings. Apart from serving as a means of communication, they also support the emergency evacuation protocol of the venue. What is an induction loop?. Not all hearing-aid users know the answer. So,the following explanation may be of some help to understand how a induction loop system works.

Most hearing-aids nowadays have a switch marked M and T. Some even have M,MT,T. The M (microphone) position is for "normal" listening, that is, receiving sound via the microphone built into the hearing-aid. The  T position is for receiving the sound via an induction coil which is built into the hearing-aid. For the induction coil to provide sound, a magnetic field is set up by a loop of wire around the area concerned powered from a special loop driver amplifier. In recent years induction loop systems have begun to be provided in public places such as churches,cinemas,theatres,offices,reception desks,lecture theatres,conference rooms, and even in the home, where the T facility is used to listen inductively. The MT position which is provided on some hearing-aids allows listening simultaneously to both airborne sound via the microphone and inductively transmitted sound via the induction loop system.

Why an induction loop ?. We all find it difficult at times to hear and understand what is said. In such circumstances, a person with impaired hearing, wearing a hearing-aid, can find it almost impossible to hear the speaker clearly. It is for this reason that more attention is now being given to assisting hearing-aid users by installing induction loop systems into churches, public buildings and in some cases, the workplace.

Hagger Electronics understands the varying requirements that users have and can design a system for use in almost any location. All we need to know are the approximate dimensions of the area to be covered. The system will need a mains power supply and can also be linked into a public address or audio system.Systems are available with upto five year parts & labour warranty.  Please send details on hearing systems More....
