Induction Loop System
Induction loop systems, also called Audio-Frequency Induction Loop Systems (AFILS) are an aid for the hard of hearing. They are a loop of cable around a designated area, usually a room or a building, which generates a magnetic field which is picked up by a by a suitable hearing aid. They are usually coupled with a public address system or sound reinforcement system to provide a clearer sound for the hearing aid user in the presence of background noise.
Infra-Red assistive listening systems are used for the same purpose however instead of a magnetic field to carry the audio signal it uses infra-red light. Infra-red does not interface directly with a hearing aid so a special receiver must be issued by the service provider upon request from the hearing aid user. This receiver is usually worn around the neck of the user and is then effectively a mini personal induction loop.
Assistive listening systems are required in accordance with the Equal Status Act 2000 – 2004, the Disability Act 2005 and the Building Regulations 2010 Part M
Induction Loop Systems must comply with the requirements of EN601118-4 2006 and BS7594 2010.
