Telecoil (Inductive Loop System)

Loop systems use a magnetic field to deliver sounds directly into your hearing aids. Sounds are picked up by an external microphone and converted into an electrical current which flows through a loop of wire. The loop of wire is either positioned around a room (e.g. perimeter of a bank or church), a chair (e.g. in a cinema or theatre) or worn by the individual themselves around the neck. The electromagnetic current is then detected by a coil of wire situated inside the hearing aid.
