An IR assistive listening system uses infrared light to transmit audio, much like a television remote control. An IR system is made up of a radiator, transmitter, and receiver.

  • IR is line-of-sight technology, and is therefore very secure for confidential transmission of the audio signal within a room.
  • To achieve maximum range and coverage of an IR system, emitters/radiators need to cover the listening area. This may require multiple emitters/radiators. The height of the emitters/radiators is a critical consideration, as well.
  • For users with a hearing aid that has telecoil capabilities, a personal neck loop can be used with the personal IR receivers.

I would not hesitate to install another Listen Infrared system in the future, and look forward to working with Listen on other projects.
