Hearing Enhancement System

Hearing Enhancement System

With the implementation of BCA Code of Accessibility 2013, new buildings and those undergoing retrofit are to be designed to accommodate persons with disabilities. One of these requirements are to aid persons with hearing disability. 

We provide consultation of the design of hearing enhancement systems and install them according to international induction loop standard IEC60118-4. Contact us for more details. 

An Induction Loop, also known as a Hearing Loop or T-Loop, is an assistive listening system that provides access to facilities for those with a hearing impairment. It takes a sound source and transfers it directly to a hearing aid without background noise. The presence of an Induction Loop should always be indicated by the use of the sign on the right.

The way an Induction Loop works is quite simple:

1) A sound source, such as a voice, TV, cinema sound system or other audio system is captured using a microphone or via a line out connection.

2) The sound signal is then connected to an Audio Induction Loop Amplifier which generates a current to pass the signal to an induction loop, usually made of copper tape or wire.

3) The copper wire induction loop (usually) surrounds the area where the listening audience is located and produces a magnetic field.

4) The magnetic field is picked up by the Telecoil (or T-coil) inside the hearing aid of hearing impaired members of the audience.

5) The hearing aid tailors the sound to the specific needs of the individual. Sound is delivered directly into the ear canal, without background noise and with the full spectrum of sound frequencies required for intelligibility.
