Using an inductive loop system,
hearing-aid wearers can pick up
the signals emitted by electric/
alternating current to the loop.

duction loop systems are defined in
Most modern hearing aids are now
equipped with adjustable »M«
and »T« functions. »M« stands
for microphone, i.e. hearing the
sound in the room via the integrated
microphone, and »T« (telecoil)
means that the audio signals are
transmitted inductively and directly
via a telecoil integrated in the hearing aid. Some hearing aids are also
equipped with an »MT« function,
which combines both types of
reception, microphone and telecoil
so that the listeners are able to hear
the sound in the room as well as the
inductively transmitted signals.
How does an induction loop
system work?
Alternating current creates a magnetic field in a wire/a loop. If a
second wire is introduced into this
magnetic field (here: the telecoil
in a hearing aid), a correspondingly alternating current will also be
created in it: the electrical impulses
are »induced« into the second
wire without any actual electrical
connection.
An induction loop system consists
of a loop and an amplifier. The loop,
an insulated wire, runs around the
outside of the listening area. The

(also known as IEC 118-4). This
standard, which HUMANTECHNIK
induction loop components meet
when installed correctly, regulates
the magnetic field strength and the
frequency range of the systems.
All induction loop systems also
comply with the CE standards,
which demand the strict control
of the equipment with respect to
interference, spurious emissions
and electrical safety.

of 2.3 to 3.8 MHz guarantees interference-free operation, unaffected
by the extraneous light from other

With a signal coverage of 2600 m²
in one-channel operation, the TX9
can also be used in large rooms.
The connection of additional

Modulator for
the operation
of the WIR TX9
transmitter
The MOD 232 Modulator is connected to the audio source. It processes these signals and sends them
to the transmitter. The transmitter
then converts this data into infrared
light impulses and sends them out
at a wide angle into the room to be
provided with coverage.
Conferences are often plagued by
limited acoustic quality. That’s why
the MOD 232’s audio-processed
signals focus on speech frequencies for well-balanced good reproduction and reduce undesirable
background noise. As a result,
people can listen to longer lectures
and events without tiring.
Like the TX9 transmitter, the MOD
232 modulator also includes an
installation kit for wall and ceiling
mounting.

RF transmission systems
Of all the wireless transmission
technologies, radio-frequency
transmission has been around for
the longest time. Not surprisingly,
then, it is also the most common,
and with respect to audio transmission systems for accessible sound,
it proves to be the most powerful
system with the largest ranges of
coverage.
Function and use of
radio-frequency
transmission systems
The basic configuration of a radiotransmission system consists of
a transmitter and at least one
receiver. The transmitter, which is
connected to an audio source – to

signals to the hearing aid.
