Assistive listening systems include FM, Infrared or loop systems. They are designed to connect the sound from the main speaker, sound system or other audio source and send the signal directly to wireless receivers worn by people with a hearing loss. The receivers allow individuals to adjust the volume to a comfortable level and can be used with a variety of headsets, including neckloop listening accessories for those with telecoil equipped hearing aids. Assistive Listening systems help to reduce background noise and compensate for poor room acoustics or distance from the sound source. Assistive Listening Systems can be portable and/or permanently installed and are recommended for all meeting assemblies where people with a hearing loss are present including; tours, lectures, small to large meeting venues, classrooms, places of worship, courtrooms, and theatres.
