The percentage of people with impaired hearing is on the increase.

Accessible sound:

Greater independence in public life for people with hearing disabilities.

The demographic shift in age has had a decided impact on this development. Hearing loss – even if only slight – can now be detected in every fourth 50- to 59-year-old.

Among people over 70, the number who are hard of hearing is already considerably higher at more than fifty percent – with significantly greater hearing loss. The percentage of people in these age groups is also expected to increase in the future.

Right to participation in cultural life

handicapped people in a general way, without any particular difficulty and without necessitating the help of third parties.«

Needless to say, the term accessibility also includes the access of the hearing impaired to acoustic information – starting with such elementary sounds as alarms and emergency signals to educational information and communications and right on up to acoustic participation in cultural and sporting events.

This so-called »50plus Generation« is very active in shaping public life. They represent a group with considerable purchasing power, take advantage of a comprehensive range of cultural offers and use all contemporary media. And they also demand – quite justifiably – unlimited access to information and communication – which constitutes acoustically accessible infrastructures in the broadest sense.

Even contemporary hearing aids are not able to guarantee good hearing and clear understanding in every situation. In noisy environments or in rooms with extreme resonance or echoes, for example, these systems often quickly reach their limits. That’s why audio transmission systems that effectively include or supplement hearing aids are now often used, particularly in places where interruption-free communication is important.

These systems feed the sound either directly into a hearing aid or a CI system or make it available to the user via special receivers.

The accessible design of public and private infrastructures

The German law for the equality of disabled persons (BGG) defines accessibility as follows: »Buildings and other facilities, means of transport, technical apparatus, systems for information processing, acoustic and visual sources of information and communication facilities as well as all other areas of life are accessible when they are useable by

National laws on equality and their implementation

The application of equality guidelines (anti-discrimination laws) is as diverse as the cultural attributes of the individual European states.

While far-reaching measures enabling equal treatment are already common in France, the Netherlands, Great Britain and Scandinavian countries, for example, the provision of accessible infrastructures is lagging behind in other countries – as in Germany.

The equal treatment of the disadvantaged and minorities has, however, now become a central concern of the European Union

(EU Basic Treaty). In this respect, the consistent implementation of accessible infrastructures – particularly in government offices, but also in restaurants, at event venues and in public transportation systems – will only be a question of time for all EU nations.

Europe’s self-image

The EU appeals to all its member states to not discriminate against anyone because of his/her personal situation. Article 26 of the Charter of

Fundamental Rights of the European Union, for example, reads: »The

Union recognises and respects the right of persons with disabilities to benefit from measures designed to ensure their independence, social and occupational integration and participation in the life of the community.«

Technical solutions for accessible sound

In addition to building acoustics and electro-acoustic public address systems (DIN 18041), the following systems can be used for a significantly higher proportion of direct sound:

Induction loop systems

Infrared transmission systems

Radio-frequency transmission systems

In order to ensure that the listening systems provided are effective, it is important to compare the requirements of the venue and its architectural features with the properties of the transmission systems early in the decision-making process.

The table (below) provides a brief overview of the main selection criteria.

The main advantage of all these systems is that the sound is delivered to the listeners in a pure, undistorted form that is not influenced by the distance of the listeners to the sound source or by any annoying background noise in the room.

HUMANTECHNIK provides a comprehensive range of assistive listening services.

The HUMANTECHNIK program is structured in a cross-system manner and includes components and the complete range of accessories for transmission systems using all three of the physical principles mentioned here. The following pages will present the technical components, list their main technical data and provide you with assistance in making your purchasing decisionl.

Special skills or knowledge are often required in the planning, project development and installation of sound transmission systems. That’s why we offer system operators and architects a comprehensive consulting and services package in this field. From qualified information to competent support in the planning process and right on up to the installation and first-time operation of the system, we will accompany you every step of the way with our consulting services to ensure the effective implementation of your professional audio transmission system.

What is an induction loop system?

Function and use of induction loop systems

Using an inductive loop system, hearing-aid wearers can pick up the signals emitted by electric/ electronic audio sources (microphone or hi-fi systems) directly in their hearing aids or CI systems.

As a result, they hear the sound without any annoying background noise, echo or reverberation. An outstanding advantage of using induction loop systems: no special receivers are required. All that’s needed is the hearing aid.

amplifier, connected with an audio source (hi-fi system, speaker’s microphone, etc.), transmits the acoustic signals converted into alternating current to the loop.

The magnetic field inside the loop allows the listeners to move freely in the room and pick up the audio signals fed directly into their hearing aids.

European standards and legislation

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.

The technical requirements for induction loop systems are defined in the European Standard EN 60118-4

(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.

Planning induction loop systems

In order to install induction loop systems correctly, it is necessary to take into account many different factors – with respect to the architecture as well as the area in which they are used. Some areas of use with special requirements include:

Rooms without equally rectangular or square floor plans

Strong steel reinforcement or electromagnetic fields from other sources

Theatres / cinemas / lecture halls

Rooms in which the loop is positioned far away from the listening level

Buildings in which several independent loops have to be installed close to one another without interfering with one another.

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

Installation tips

Loop position: In order to create a uniform magnetic field, the distance between the loop level to the normal listening level should be between approx. 1.2 and 2 metres.

The position and size of the

loop can also be determined by the position of the listening area

(often much smaller than the size of the room) or the position of the microphones as well as other technical equipment that affects the magnetic field.

If possible, avoid using dynamic

microphones in combination with induction loop systems. If they cannot be avoided, they must be positioned outside the loops. The distance between the loop and the dynamic microphone should be at least half the diameter of the loop.

Recommended loop wire cross-sections:

Loop area

200 - 300 m²

150 - 200 m²

70 - 150 m²

< = 70 m²

The values indicated can be used for most induction loop systems.

For special solutions, please contact HUMANTECHNIK. H07V-K, for example, is recommended as the induction loop wire to use.

Using a condenser or electret

microphone usually produces better results with respect to interference or acoustic feedback.

A microphone with a high-quality, insulated connection cord also generally reduces magnetic feedback.

Reduce the area of the loop! The connection wire to the loop must be firmly twisted or closely parallel.

Conducting materials, such as

reinforced concrete, can increase or decrease the area covered by the loop. The magnetic field strength is often increased outside the loop, while it is decreased inside. This fact considerably increases the risk of acoustic feedback. In a new building, you should try to install an LOS system. The LOS system makes it more difficult for the current to connect with large metal objects. Make a test installation. Always test the loop system to make sure that it is powerful enough, that the overspill does not cause any problems, etc.

Pay particular attention to metal

frames. Do not fasten the loop to structural elements made of metal or to similar objects.

Adjust the height of the loop (1.2

to 2.0 m) to provide for the greatest possible range with the smallest amount of overspill.

Notes on the installation of induction loop systems

Loops are generally laid around the outside perimeter of the room.

The audio signals are then inductively transmitted to all the »coils« inside the loop.

Standard induction loop systems produce a magnetic field that usually exceeds the »core service area«. This »overspill«, which travels horizontally and vertically, might still be audible three to four loop widths away. This limits the use of this technology.

An LOS system consists of two induction loop amplifiers that are operated out of phase. This configuration prevents overspill and makes it possible to operate several induction loop systems in adjacent rooms without having their signals interfere with each other:

Low-overspill systems expand the application options of induction loop systems.

Low-overspill systems

(LOS): Induction loop systems with low overspill

Low-overspill systems (LOS) considerably reduce »overspill«. They use special loop patterns to reduce the signal strength outside the loop.

For these patterns, two loops have to be operated out of phase with each other to achieve an equal distribution of the desired signal without creating any undesirable signal-free areas.

No field strength reduction in the centre of the loop due to reinforced concrete,

Greater reproducibility of the results,

Reduced danger of feedback due to lower power consumption,

Extremely low overspill at reduced directional sensitivity.

HUMANTECHNIK service for planning low-overspill systems

Each individually optimal customisation and configuration depends on the conditions prevailing in the area of application, in other words, on the room floor plans and the sizes of the coverage areas, the number of internal loops and the demands made on low overspill.

Determining the corresponding values for the »customised« lowoverspill layout and the optimal level adjustments in each case is based on a complex method of calculation and installation. That’s

why we strongly recommend that you take advantage of the ser vices offered by HUMAN-

TECHNIK. We provide competent support to architects, technicians and installers in planning LOS installations.

The overspill of standard induction loop systems works in a horizontal and vertical direction.

The resulting »eavesdropping effect« is often still measurable over distances of up to three induction loop widths.

Low-overspill systems

(LOS) that are competently customized and configured reduce overspill considerably to allow the operation of induction loop systems in directly adjacent rooms.

»Function and use of infrared transmission systems«

How does an infrared audio transmission system work?

An IR audio transmission system consists of at least one transmitter and one receiver. The transmitter is connected to an audio source – to a microphone system, for example – and transmits the signals received in the form of infrared light impulses wirelessly to the receiver, which converts the light impulse received into electrical audio signals and feeds them into the reproduction device connected – into headphones, for example, or a teleloop for the inductive direct transmission to hearing aids.

for certain large professional

applications.

Advantages of infrared transmission technology

This applies in particular to venues and facilities, ...

... in which the confidentiality of the information exchanged there plays a decisive role, for example in courtrooms or conference rooms, and areas, ...

... in which several transmission systems are operated parallel to one another in neighbouring rooms, such as in multiplex cinemas or in living quarters in social facilities.

Areas of application

Apart from the home environment, in which the wireless reception of audio signals via infrared light has long since become a popular alternative to the corresponding radiofrequency transmission systems, this technology proves superior to all other transmission principles

In addition, infrared audio transmission systems have proven valuable in schools and universities, in large auditoriums with partial signal cover age or in city centres, in which there is a very high rate of radio-frequency emissions.

Infrared light signals cannot pass through walls, which reduces reception to the room in which the transmitter is installed.

Transmission is reliable and absolutely free of the interference caused by electromagnetic fields or structural elements in the building, such as metal reinforcements. In addition, these systems do not produce any electromagnetic emissions themselves.

Infrared transmission systems can be used easily in many different countries; an »obligation to register« them, similar to the allocation of radio licenses, is not required.

The transmitter sets up an

»infrared signal route« to the receivers of the transmission system. The transmitter’s large signal emission angle or the wide signal dispersion and the reflection from walls, ceilings and floors guarantee reliable reception – for the most part, even when smaller obstacles (furniture or pillars) block the direct

»line of sight« between the transmitter and the receiver.

16

Coverage

While the range of systems designed for private use is limited to about 10 or 20 metres, high-

powered infrared transmitters are able to provide coverage for much

larger rooms. The transmitters described in this product overview, for example, are able to provide coverage for up to 2600 m².

Other factors affecting infrared transmission technology:

The transmitter does not focus the emission of the infrared light impulses, i.e. it uses a very large transmission angle.

As a result, there is generally no need for a specific »line of sight« between the transmitter and the receiver.

Other characteristics of infrared audio transmission systems:

Portable/mobile systems are available.

Multi-channel operation provides for flexible use, making it possible to simultaneously transmit several different languages, for example.

The signals do not only travel directly between the transmitter and the receiver, but are also reflected from the walls, cei lings and floors. Nevertheless, pillars and furniture – depending on their size and position – can interfere with or even block reception under certain conditions.

Receivers are compatible with

TV listening system for at-home use.

In any case, a technically

correct, precise positioning of the transmitters is required for optimal signal coverage.

Light-coloured floor, wall and ceiling areas reflect infrared energy more strongly. This can increase the reception range.

Dark, low-reflection floors, ceilings and walls absorb the energy and can limit reception ranges as a result.

The carrier frequencies of 2.3 to 3.8 MHz (basic band) minimize the probability of interference resulting from powerful lighting. However, functional problems due to direct sunlight cannot be ruled out altogether.

Reliable, inconspicuous audio transmission for rooms up to 2600 m² in size

In order to provide coverage for areas that exceed the maximum range of the individual transmitters, it is necessary to install several transmitters at different locations and connect them in parallel.*

* If the reception range is the main criterion for the application in this context, it is advisable to consider the use of a radio-frequency system

as an alternative – also taking into consideration the cost factor (

p. 22 ff.

).

The signals are transmitted to the hearing aid via a special infrared receiver with audio amplification equipped with a teleloop

(induction).

If the receiver is equipped with an audio output jack, it is also possible to use headphones or earphones.

Amplifying infrared audio receivers are available as pocket devices, underthe-chin receivers, headphones with reception diodes or in the LR version with a teleloop and audio output.

»MOD 232« modulator

Order No.: A-4029-0

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.

as a modular system, it offers not only easy expansion with respect to the audio coverage (

also see diagram, p. 21 ). It also presents

new prospects for greater application flexibility.

Configuration examples for audio using infrared transmission systems

TX9 transmitter and

MOD 232 modulator: the standard configuration

The MOD 232 modulator serves as the »interface« between the audio source and the infrared transmitter. The standard configuration allows one as well as two-channel operation.

Typical applications:

Simultaneous transmission in different languages

Media rooms

Courtrooms

Theatres

Churches

Educational facilities

TX9 transmitter and MOD 232 modulator as a 4-channel system

Using the components as a 4-channel transmission system requires two MOD 232 modulators and two

WIR TX9 infrared transmitters. This combination presents high flexibility for a wide range of applications at an attractive price – particularly in areas that require the simultaneous provision of information in several different languages.

In four-channel mode and using the four-channel RX22-4 receivers

( see p. 22 ), the transmission sys-

tem is able to provide coverage for approx. 1000 m² in its standard configuration.

The components can be used as a stationary installation (e.g. 19” IEC rack mounting for the modulator) or as a portable system with easy setup and convenient operation.

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 a microphone system or any other audio system, for example – picks up the audio signals to transmit them wirelessly to the receivers.

Amplifying receivers with audio output jacks are also available and can be connect to the earphones or headphones.

Areas of application

Radio-frequency audio transmission systems have already become well established as wireless headphones or TV listening systems in the home environment.

The systems described in this brochure, however, go above and beyond this, most importantly because they have been designed for professional applications – for example:

in sport arenas or at other spacious event venues,

in churches and other assembly halls, The receivers can be equipped with teleloops, which provide for the inductive transmission of the signals to the hearing aid.

in lecture or seminar rooms, as in schools and universities,

and for open-air applications in particular, there is hardly an alternative to radio-frequency transmission.

In addition to these stationary applications, portable, so-called tourguide systems have also proven useful in many areas. Some of the areas they can be used in include

museums, art galleries,

tourist attractions and special events

or transportation.

The availability and use of several channels makes it possible to pro vide different information at the same time, for simultaneous interpreting into different languages, for example, or for the treatment of different topics for several listening groups located close to one another.

28

Due to their ability to provide large coverage and independence from floor plans and architectural structures, radiofrequency transmission systems are also ideally suited to open-air applications.

Radio-frequency signals are able to easily pass through walls. The listeners can leave the room in which the transmitter is installed at any time without any problem and their RF receivers will continue to provide them with the information they need.

Outstanding features of radio-frequency transmission technology

Transmitter and receiver do not require a direct »line of sight«.

Radio waves can pass easily through normal house and building walls. Listeners take the sound along, even when they leave the room in which the transmitter is installed.

This means that even very large areas can be easily supplied with audio signals.

It is relatively easy to install RF transmitters, which also makes it inexpensive. The costs for installation and hardware do not increase in proportion to the size of the area that requires coverage.

The transmitters can be installed inconspicuously

(except in metal enclosures) and do not mar or spoil the overall architectural picture.

Sunlight, artificial light and the reflection conditions inside rooms do not affect transmission.

RF transmission systems are easy and convenient to use, they are very portable and, with multi-channel functionality, they are very flexible in their uses and applications.

Some countries charge radiolicensing fees for the use of these systems. In this context, it cannot be ruled out that the national regulations in some countries only release certain frequency ranges for these systems (different from the standard).

Coverage

With respect to coverage, RF transmission systems are far superior to the two other transmission technologies described in this brochure.

With coverage ranges of up to more than 300 metres, it is possible to easily supply even large arenas with audio signals. The transmission distances of tour-guide systems with approximately 30 metres makes it possible to supply information even in large groups or groups in different locations.

Factors influencing the operation of radio-frequency transmission technology

More useful information on the use of radio-frequency transmission systems

Users of audio radio-frequency transmission systems should be aware of the fact that the coverage ranges or the signal scattering go beyond the intended coverage areas. As a result, there is no guarantee that the information transmitted will remain confidential.

When planning the parallel use of this type of system – in neighbouring rooms, for example – the transmission must be made on different channels

(compare the number of channels available with the number of channels required).

Other RF systems or electromagnetic emissions could have a negative effect on transmission and signal quality.

An attractively priced, functional solution designed to provide large areas with audio signals

Users must make sure that their transmission channels are set correctly.

Convenience in operation, flexibility in use

The CM system transmits the audio signals inductively via the teleloop to the hearing aids. The CM-1 receivers are also equipped with an audio output jack.

Equipped with an acoustic zoom function and an omnidirectional setting (spatial hearing), the directional microphone is able to provide the suitable angle for sound reception for a variety of different situations.

Outstanding voice quality

The speaker can wear the microphone on a neck cord or place it nearby, on a table, for example. The microphone transmits the signals it receives via radio waves to the receivers, which the listeners wear or carry.

Three channels to select

CM-1 is equipped with three radio channels to choose from so that up to three CM-1 systems can be active at the same time without interfering with one another.

Operation is easy and quick to learn. As a result, listeners can make their own individual settings as soon as they get their receivers.

A knob is used to adjust the volume to any level desired, while a treblebass switch makes it possible to adjust the tone.

DSP technology processes the audio signals in real time on the basis of audiological criteria. Any undesirable ambient noise is suppressed and voice frequencies are accentuated. The AGC function

(Automatic Gain Control) controls the adjustment of the volume to the current acoustic situation.
