Audio Induction Loop
loop Audio induction loop systems, also called audio-frequency induction loops (AFILs) or hearing loops,[1] are an assistive listening technology for individuals with reduced ranges of hearing.[2] A hearing loop consists of one or more physical loops of cable which are placed around a designated area, usually a room or a building. The cable generates an electromagnetic field throughout the looped space which can be picked up by a telecoil-equipped hearing aid, a cochlear implant (CI) processor, or a specialized hand-held hearing loop receiver for individuals without telecoil-compatible hearing aids.
The benefit is that it allows the sound source of interest – whether a musical performance or a ticket taker's side of the conversation – to be transmitted to the hearing-impaired listener clearly and free of other distracting noise in the environment. [3] Typical installation sites include concert halls, ticket kiosks, high-traffic public buildings (for PA announcements), auditoriums, places of worship, courtrooms, meeting rooms, and homes. [12] This standard specifies long term average field strength with allowance for program peaks, background noise level ,and frequency response.
