Принцип действия прибора вот такой же как на картинке , только вместо телефона - микшерский пульт, который вы видите в чемодане, а петля огромная на весь демонстрационнный зал , охватывает одновременно сотни человек.
Упрощенный принцип действия, петля вокруг зала.

An induction loop system is a loop of wire that is installed around the perimeter of a listening area and it emits a magnetic field. The loop receives its input signal from a sound source such as the public address system in a theatre, church or other public venue. Most modern hearing aids are compatible with loop systems. Compatible aids feature a ‘T’ switch. With the switch set to the ‘T’ position the wearer can hear the sound source directly via the loop, bypassing the hearing aids microphone.
Where do I find loop systems?Venues that provide a loop system display the “Ear” symbol. Many public buildings are wired with loop systems. Sometimes loops systems are not turned on or are broken, so you must ask if you are unsure. If you are not certain, try switching your aid to the ‘T’ position. If your hearing improves, it is picking up the loop system. If you hear a buzzing sound or a wind-like noise, then there is no loop system working. You will find loop systems in many public buildings and on some telephones. Some people have them installed in their own homes. Some telephones will often specify it is “Hearing Aid compatible,” which indicates it will receive the loop signal.
For information on loop system availability at popular venues all over NZ just consult the venue listing here. Is my hearing aid compatible with a loop system?Most modern hearing aids are compatible with loop systems, or can be made compatible. You will need a ‘T’ switch option on your hearing aid. If you are not sure ask the staff at Hearing Consultants. Some hearing aids have an ‘MT’ option, which means the wearer has the best of both worlds, hearing via the microphone and via the loop system simultaneously. |
Induction
loop systems consist of a thin wire that is placed around the listening area*,
a special amplifier and microphone(s). Speech signals are amplified and
circulated through the loop wire. The resulting magnetic energy field is
detected and amplified by the "telecoil" or telephone switch
circuitry common to many hearing aids, cochlear implants and induction loop
receivers. The end result is a high quality amplified reproduction of the
original speech signal. Intelligibility is greatly increased because the
distance between the speaker and the listener(s) is bridged and background
environmental noise is reduced. (Click on

Отдельные элементы находящиеся в чемодане:
wireless microphone TOA WM-370 беспроводной радиомикрофон
Audio-Technica Power module, 9-52V phantom power or 1.5V AA
battery, TB3M in
The Audio Technica AT8531B is an in-line body-pack
power supply for AT series gooseneck and overhead microphones. The unit is
designed to supply 9 to 52V phantom power and uses AA batteries. A low
frequency roll-off switch is provided and minimizes structure and wind noise
and a belt clip provides added stability. The unit features a TB3-male input
and standard 3-pin XLR-male output connector.
Audio-Technica Omnidirectional condenser boundary microphone,
battery/phantom
The Audio-Technica U841A is an omnidirectional
boundary microphone designed for highly intelligible sound reinforcement,
professional recording, television and conferencing in surface-mount
applications. The microphone's omnidirectional polar pattern is capable of
accurately reproducing audio at 360 degrees. The surface mounted U841A
features a polarized condenser element that reproduces audio with crisp
detail and pristine fidelity. UniGuard RFI-shielding protects against radio
frequency interference. The microphone is powered via phantom or 1.5V AA
battery power, an external in-line phantom power supply is included. The
U841A is an excellent choice for capturing conferences, meetings,
broadcasts, performances, ambiance and more.

приемник
Mono stethoset receiver receiving 2.3MHz (Ch.1). RI 150LL has an integral neck induction loop for the hard of hearing.
Wideband distribution systems can offer high quality audio for music or speech distribution over a large area for uses such as hearing support systems or audio commentary in auditoria. A variety of radiators and receivers are available depending on the application. Full manufacturers details and technical specifications available on request.
SOUND INDUCTION SYSTEMS
Infrared
An alternative to an induction loop system is an infrared system. Infrared systems are used when confidentiality is an issue, adjacent rooms are to be installed, a multi channel system is needed i.e. for hearing impairment support and translation, easy portability or an induction loop simply can’t be installed for technical or financial reasons.
Infrared systems use invisible infrared light to carry the sound to wearable receivers. There are two types of receivers, a stethoset which convert the infrared light to audio and a neck loop which convert the infrared light to a personal induction loop. Each receivers has a rechargeable battery pack which can be easily charged in charging racks.
The infra red light is transmitted by infrared radiators (shown above). These radiators are available in a number of different models depending on the distance and area to be covered.
