Infrared systems are a great alternative assistive listening solution when circumstances prevent hearing loops being installed. In many cases hearing loops and infrared systems can work together to provide full coverage for a venue.
Ampetronic are proud to be the strategic partner for Williams AV and distributor of IR systems in the UK and distributor partner in Europe.

Assistive listening technology assist people with hearing loss who can struggle to hear in busy or noisy environments, or in situations where there is a significant distance between them and the sound they want to hear.
What is Assistive Listening?
Assistive listening technology for hearing loss works by capturing a sound source and transmitting it directly to a receiver that in-turn delivers it directly to the user’s ear, with minimal background noise, interference or distortion.
What are the different types of technology?
There are currently three main assistive listening technologies for commercial applications Hearing Loops, Radio Frequency and Infrared. Each technology has its pros and cons; what may work really well in one type of environment, but may not be suitable for another application.
Which technology shall I use for assistive listening?
Dependant on the environment and situation the type of technology required will vary. We still advocate that where fixed installations are required that hearing loops are the preferred technology of choice. Where this is not possible or where hearing loop installation may be considered invasive then our Infrared and Radio Frequency technology provide an exceptional alternative for other situations. Audio over WiFi can also be used in circumstances where the user is expected to bring their own device, although this is more frequently used for multi-channel entertainment purposes.
How do they work?
Hearing loops function by creating an alternating magnetic field at audio frequencies which provide an input signal for a Telecoil enabled hearing aid, cochlear implant or hand held receiver.
Williams assisted listening solutions like Infrared works by sending an audio signal to an Infrared receiver which turns the signal into audio via DSP (Digital Signal Processing). Our UK Radio Frequency uses a microphone line in to send an audio signal to the radio transmitter which then broadcasts a 863 MHz radio signal which is then picked up by the receiver.
