Although Deaf Aid loop systems have been around for a considerable period of time, they are still not well understood, and many systems do not achieve an acceptable standard. Deaf aid loops—or AFILS as they are formally known—are installed in all forms of venue or public building raging from churches, theaters, and cinemas to railway and underground stations. Loop systems can vary from large systems covering many hundreds of seats to counter-top systems intended for individual users. The workshop will review the theory and practice of Audio Frequency Induction loop systems (AFILS) as well as discussing other technologies such as infra red. Ways of optimizing system performance and day to day problems will be discussed.
