Inductive heating system: relief for the hard of hearing

As people get older, their housing assets sometimes decrease significantly. After retiring from working life, there is also more time to attend events of various kinds. In theaters and lecture halls, however, it is usually particularly difficult for hearing-impaired people to receive appropriate audio signals. An inductive hearing system can help here.

What is an inductive heating system?

Inductive hearing systems, also known as induction loops, are mainly found in public buildings such as theaters and other lecture halls. The listening system can transmit the corresponding audio signals from these lectures directly to the headsets of the visitors. This allows you to enjoy public events to the full, even in old age.

How does an inductive hearing system work?

In order to pass on the signal, a signal source is fed into an amplifier. Instead of a loudspeaker, an induction loop is connected to this amplifier. The induction loop is usually a flat ribbon cable. The latter is laid in the room, creating a magnetic field. The telescopic coil of the respective heater is immersed in the magnetic field of the induction loop, which generates an alternating current in the heater. However, an inductive hearing system only works if the heater is switched from M (microphone) to T (telecoil).

Loop designs

Sometimes a loop is not enough to generate a uniform magnetic field. This is where various loop designs can help. These include, for example, so-called phased array loops. Several inductive loops play together. So-called low overspill loops are particularly helpful if safety is to be ensured, as this design can limit the magnetic field to a corresponding height.
