Induction loop systems, otherwise known as audio frequency induction loop (AFIL), are a system that is utilised to assist those with hearing impairments as it allows them to be able to hear and listen a lot more clearly. They work by taking a source of sound and transferring it via magnetic waves directly to hearing aid whilst cutting out any background noise or interference with the sound waves.
Since 2004, it has been a legal requirement to have induction loop systems installed in any service or function building as means of disabled access, however they were becoming increasingly popular before that. Over the last 25 years or so, induction loop systems have quickly become the default system to aid those with hearing impairments across Europe. Because there are so practical, low maintenance and incredibly easy to use, they are now found in a diverse range of daily use industries such as banks, schools and other public buildings, even going as far as being installed in vehicles like taxis and buses.
