What is an Audio Frequency Induction Loop System (AFILS)? A simple, license free way to transmit sound, without wires, to listeners who have a hearing aid or suitable receiver.

How Does It Work? In its simplest form, a special amplifier takes a signal from the TV or PA sound system and transmits the sound via a loop of wire or flat copper tape placed around the perimeter of the area to be covered. The wire can be hidden under carpet or behind plaster and the signal will travel quite happily through brick walls, plaster, wood, metal (some) etc. to provide clear, loud audio. Note that rooms containing metal (reinforced concrete, mesh, metal frames or suspended ceilings) will need more elaborate systems to overcome losses.

Who can use them? Anyone with an inexpensive receiver. However they are especially useful for the hard of hearing who can switch directly into the system by using the "T" or Telecoil position on any standard hearing aid. They can also be used in tour guide setups in a museum or art gallery to give a running commentary about specific exhibits, or in the home connected to the TV. In a secure interview situation where the interviewer needs a comms link that is radio scanner proof etc etc....more

Where Should An Induction Loop System Be Fitted? Installing and operating a loop system is very easy for anyone with a little practical knowledge. All the circuits use ultra low voltage "safe" electricity unless you have a massive system. However designing the loop in the first instance is a complex mathematical process that must be done professionally otherwise your loop just will not work properly.

Induction Loop Systems are set to become a standard feature both at home and in ALL public buildings where assistance with hearing is required. If you are responsible for running a church, stadium, museum, bank or theatre, you can advertise your venue with additional facilities that will genuinely help those with poor hearing and that has to be good for business, even opening previously excluded markets in some circumstances..... How do I get one fitted?

Why is this service Unique? Because it allows you to get a feel for what equipment will be needed in any particular installation, large or small. You can then cross check against your suppliers specifications and ensure you have a viable system. All we are interested in is promoting the best quality of installation for the hearing impaired. If you have any questions or difficulties understanding the concept or practicalities of Induction Loops, please contact Ampetronic who have a dedicated team of real engineers waiting to answer your questions (+44 (0) 1636 610062) or email.
