Infra Red Listening & Hearing Systems

Infrared assistive listening sysems consist of a transmitter and receiver.



Simply plug in your audio source (be that a microphone, TV, PA etc) and the tranmitter sends the signal via infrared to a matched receiver. Plug in a 3.5mm neckloop and the hearing aid user has a personal induction loop to assist hearing. An infrared listening system is one of the simplest, most secure methods of satisfying the requirements of the hearing impaired and the legeslation intended to protect them. The great advantage is the signal cannot spill over into other rooms and mulitple devices can be used and therby avoiding any radio licencing problems.

Please Note: Infra-red receivers operating in the low band (95kHz and 250kHz) can suffer from fluorescent lighting interference. In cases where high frequency fluorescent and/or incandescent lighting are used (this includes modern energy-saving lamps) the infra-red signal may become unusable. In these cases use the high frequency infra-red systems operating above 2MHz.
