.
Inductive transmission of audio signals allows users of
hearing aids with a T-coil or induction loop receivers,
e.g. the LR-202, to receive audio signals. Wireless
transmission is an advantage of audio induction loop
systems which makes it possible for the user to move
freely within the loop.
Induction loop systems are used for various applications,
e.g. as a hearing aid for the hearing impaired in
houses of worship, theatres, cinemas, waiting rooms
and lounges, as interpreting systems, for lectures in
museums, exhibitions, etc.
With induction loop systems, an induction loop made of
a wire winding is laid on the floor, the wall or along the
ceiling and is controlled by a constant current amplifier.
Thus, a magnetic field is created within the loop which
induces a voltage into the T-coil of the hearing aid or
into the induction loop receiver.
This voltage is then converted again into an audio signal
in the receivers.
