Also known as Induction Loops or Audio Frequency Induction Loop Systems (AFILS), consist of a copper wire placed within a room, theater, or counter which is connected via a special loop “driver” to a public address or sound system. An electromagnetic field is created that connects to a telecoil in hearing aids, cochlear implants, or telecoil receivers. Loops are the most user-friendly of assistive listening options. Hearing loops are simple, discreet, and effective. Users simply switch their devices to the telecoil program and automatically receive clear, customized sound directly to their ears.
