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.
Induction loop systems utilize electromagnetic energy to transmit the signal. These systems can cover a small area with a loop placed under a rug or may be permanently installed within the walls or ceiling of larger areas like theaters, auditoriums, or churches.
They can be used with telephones, FM systems (with neck loops), and induction loop systems (also called "hearing loops") that transmit sound to hearing aids from public address systems and TVs. In the UK and the Nordic countries, hearing loops are widely used in churches, shops, railway stations, and other public places.

Such an induction loop receiver is classically a very small iron-cored inductor . The system commonly uses an analog power amplifier matched to the low ...

REAT systems rely on the subjective response of the person being tested to determine auditory thresholds much like a hearing test where the subject indicates when sound is heard at various frequencies. According to the acoustic standards, REAT testing of hearing protection devices must be tested in an acoustic chamber with a diffuse sound field.
