Installing Induction Loop Systems in Singapore

Conference Room

An Induction Loop System, or a Hearing Loop System, is a specialized audio system that uses electromagnetic energy to transmit sound directly to hearing aids and cochlear implants. This system is designed to assist individuals with hearing loss better understanding speech and other sounds in various settings, including public spaces, homes, and workplaces.

 

An Induction Loop System consists of a loop of wire placed around a room or area and a loop amplifier that interfaces with a microphone or other audio source. The audio signal is then transmitted through the loop wire, which creates a magnetic field that can be picked up by hearing aids and cochlear implants that have a telecoil or "T-switch" setting. This setting allows the hearing aid or implant to receive the magnetic signal and convert it into sound, eliminating the need for additional devices.

 

Note: Only hearing Aids with a Telecoil will only be able to enjoy the Induction Loop Systems.

Pre-installation questions

Before installation, here are some of the things we will initially ask these questions to help us:

  • Floor plan - this is for us to understand the size of our work area, what would be provisioned nearer to the completion of the project, and for us to design the loop per the customer's requirement.
  • Type of floor finishing - will help us understand whether factors affect the desired or expected results, such as the high presence of metals, resulting in reduced audio signal clarity.
  • Listening Height - whether for sitting or standing, different heights will require different settings on the amplifier.
  • Audio Source Location - this will enable us to know where to start and end the loop during the installation phase.
  • Bolting points on the floor - allows us to make a more effective design and to divert away from them so that the loop does not get damaged during the installation of furniture and carpentries.

Installation time frame

A typical time frame for an Induction Loop System Installation is as follows:

  1. Training Room / Conference Room - 1 day
  2. Full Gymnasium coverage - 2 - 3 days
  3. Retractable Chairs - 3 days
  4. Full Auditorium coverage - 3 to 4 days

In conclusion, an Induction Loop System is a specialized audio system that uses electromagnetic energy to transmit sound directly to hearing aids with telecoil.

 

This system is designed to assist individuals with hearing loss by providing better and clearer speech and other audio sources in various settings, including public spaces, places of worship, and workplaces. With the clear and direct sound provided by the Induction Loop System, individuals with hearing loss can enjoy a better quality of life and space than regular people.

How Induction Loop Systems are More Superior to FM or IR Systems

Conference Room

Induction Loop System is an audio technology that supports enhanced hearing and communication for individuals with a hearing impairment.

Audio Induction Loops, occasionally called Hearing Loops, deliver an assistive listening system for individuals with hearing impairment, specifically those who use a hearing aid.

But how are Induction Loops more efficient than an FM or IR System?

  1. One of the main advantages of Induction Loops over FM and IR systems is convenience. Both the user and the venue benefit from the convenience factor. With Induction Loops, users do not need additional equipment or devices as the system directly links with the user's hearing aid or cochlear implant.
  2. Another benefit of Induction Loops is that they can be less costly than other systems like RF and IR for larger spaces. Large venues for the Loop system are more cost-effective than using IR and FM for large venues.

Take this example: Each hearing aid user requires one receiver, and the support of 100 hearing aid users will be the receiver cost multiplied by 100, which will be more expensive than the loop. While RF and IR systems cost less because buildings do not need to be modified to install them, Induction Loops can be a more cost-effective solution in the long run.

  1. Induction Loops offer a complete range throughout a venue and are less prone to interference than other systems. For example, in FM systems, the signal quality can be affected by obstacles, such as walls or people, which can cause interference.
  2. Induction Loop Systems use a magnetic field and equip hearing access the same way wherever installed. They function at airports, ticket windows for trains or buses, and service counters where passing out and getting back an IR or FM receiver is impossible.
  3. Induction Loops and IR systems offer greater privacy for users and the venue than FM systems. With FM systems, the signal can travel beyond the intended listening area and potentially be heard by others, compromising privacy.
  4. It is worth noting that the efficiency of hearing aid systems can vary based on individual needs and the specific venue or environment in which they are used. Therefore, consulting with a hearing healthcare professional is essential to determine the best assistive listening system for a particular situation.
  5. Induction Loop Systems are sanitary. There are no hygienic considerations when one uses their hearing instrument as the receiver.
  6. The induction loop system provides an intelligible sound quality, whereby the hearing aid user will be able to experience with their hearing aid that has been tuned to their unique hearing loss profile, allowing them to get the best possible experience out of the induction loop system.

With all the various benefits of hearing loop systems, why do some venues still install IR or FM systems?

  • IR and FM systems can still be less expensive than hearing loop systems, especially for smaller venues or venues with a limited budget.
  • IR and FM systems may be more compatible with existing audio systems in a venue, making installation and integration easier.
  • IR and FM systems are typically more focused than hearing loop systems, making them a better option for venues where privacy is a concern, such as courtrooms or medical facilities.
  • IR and FM systems have existed longer than hearing loop systems and may be more readily available in certain regions or countries.

Efficiently, The Listening Lab understands this intimately as we are the only audiology retail chain implementing hearing enhancement systems in buildings. We understand what the users are going through and how a sound system helps the hearing aid user cope much better. We also understand building owners' and designers' requirements and expectations to deliver an integrated, hassle-free solution.

The Benefits of Installing Hearing Enhancement Systems in Schools and Universities

Audio Video Room

When planning renovations or restructuring for a school or university, one should consider installing a Hearing Enhancement System. This system operates in the background and increases the clarity and quality of an input sound source for individuals who use a personal hearing aid or device with a built-in telecoil feature.

How can this be advantageous for school systems?

Institutions like NTU, SMU, Singapore Polytechnic, and The Canadian International School have used loop systems. They can be installed in public spaces and rooms to meet specific needs. Hearing loops are often the most efficient option as they help reduce background noise while allowing students with hearing impairment to be part of the same environment as everyone else. This results in improved clarity while ensuring that speakers wouldn't have to strain their voices and everyone experiences a more nurturing atmosphere - enabling students with hearing impairment to learn with fewer disruptions and can better understand what is being taught.

 

Hearing Enhancement Systems play a crucial role in the education sector, where many may experience hearing loss. The two main types of Systems are personal hearing aids and FM systems. The latter uses a neckloop that receives FM signals from a transmitter such as a Teacher's Microphone or an audio source from a Line Input. And then into currents that travel through the neckloop—creating a magnetic field which then induces the telecoils in hearing aids, enabling the individual to hear what everyone else hears during lectures given by the presenter.

How does it work?

A hearing loop, an induction loop or T-Loop, is a technology designed to enhance the audio experience for individuals with hearing impairments. It transmits a sound source directly to a hearing aid, eliminating background noise or acoustic distortion.

 

When selecting a hearing loop solution, it is essential to consider the type of environment the institution will use it. For example, an area coverage solution is required in an ample public space such as an auditorium or theatre when a lecturer interacts with a group of people. A service point solution is necessary if the school uses it at a service point, such as a retail counter or reception desk, where there is a direct line of communication between the hearing aid user and counter staff.

 

The following information is essential to determine the ideal solution for a specific area:

  • The venue's area coverage and dimensions: the size of the room will affect the power needed to drive the hearing loop effectively and provide quality, consistent and clear coverage for hearing aid users.
  • The floor construction: metal elements such as beams or even rebar in the floor or ceiling structure can have a minor or significant impact on the signal levels and cause variations in the audio clarity. Hence, to overcome this challenge, the space may need a MultiLoop system to correct this.
  • Regarding adjacency or privacy: a perimeter loop tends to spill over into adjacent areas, such as neighbouring classrooms or rooms where one's privacy is desired. This should be taken into consideration when selecting a hearing loop solution.

Check this video: How Hearing Loops Work, to learn more about how they work. The Hearing Enhancement System by the Listening Lab is the appointed sole distributor of Ampertronic products in Singapore and Malaysia for the South East Asia Region.

Convenient places for installation in schools

A hearing enhancement system for the general public makes schools more inclusive for guests and students. Therefore, lecture halls, gymnasiums, and auditoriums are the best places where Hearing Enhancement Systems would install hearing loop systems. Institutions can utilise Hearing Loop solutions during events and assemblies, such that individuals who use hearing assistive devices can enjoy the moment without having to stand close to an audio output like speakers or being left out and constantly look out for assistance.

 

It is also convenient to install at cashiers or public service counters to improve sound clarity even with heavy background noise. The counter staff will be able to communicate with the hearing aid user via a dedicated microphone which will transmit the signal without disruption from the background noise. This counter loop system is also effective when communication is done between a glass window if there is one.

 

The Hearing Enhancement System by the Listening Lab designs and builds low-spill multiloops that equip communication privacy within a defined area required by clients. This guarantees that rooms that need to be hearing-aid friendly can also be secure for the specified audience. We offer multiloops which provide communication privacy within selected areas, ensuring that rooms with hearing accessibility remain safe for their end users.

 

The Hearing Enhancement System by the Listening Lab offers comprehensive solutions for any environment. Schools are constantly battling the challenges of inclusivity for the deaf and hard of hearing, and having a quality and professional solution service is a way to address that. For more installation information and or quotations, you may call us to inquire further.

Do We Really Need Hearing Loops?

Audio Video Room

Why would anyone invested in hearing aids or cochlear implants require anything more than their devices? Don't hearing aids mend a hearing issue like prescription eyeglasses can provide better vision?

 

It does not.

 

Today's hearing aids improve hearing in casual settings. For those with hearing loss, the sound becomes vague when loudspeakers are far away, when the context is noisy, or in rooms that resonate sound. A hearing loop magnetically transfers a microphone or TV sound signal to hearing aids and cochlear implants with an affordable "telecoil" receiver. This alters the mechanisms into in-the-ear speakers that produce sound customised for one's hearing loss.

Distance Difference

Beyond 6 feet, people generally use a Bluetooth system in their home or office to drive the audio signal from their TV or sound system straight to their hearing aid. That works in a range of up to 14 feet.

 

Beyond 14 feet, the space from the primary audio origin to the hearing aid is so far that it merges with the other background noises. That distance also generates reverberation and contortion boosted by the amplifier built into the hearing aid. All of that conducts to higher volume — but significantly reduces clarity and understanding for the person wearing hearing aids.

 

The solution in more expansive, noisy spaces: shorten the span that sound has to traverse by generating an audio induction loop field that a telecoil receiver can pick up from anywhere in the looped area. Most hearing aids and implants are compatible with this system. Individuals need to be sure they know how to trigger their telecoil. (82% of aids and 100% of implants have a built-in telecoil.)

 

Therefore, Hearing Loops are certainly recommendable in public spaces.

 

A user-focused method founded on each area's requirements will specify and provide a loop system with a faultless listening experience.

Why are Induction Hearing Loops important?

Audio Video Room

Hearing loop systems are answers for assistive listening, providing access to high-quality discernible sound for hard-of-hearing individuals. Why are hearing loops critical? The methods are beneficial to those with hearing loss, and the need for them is rapidly growing around the world:

 

  • Assistive listening benefits an extensive and ever-growing section of the community - hearing impairment affects one in seven individuals, a number that is expanding as the population ages. Equipping fair and high-quality assistance to this large group is becoming a high priority for any service provider or public organisation.
  • Hearing loop systems offer distinctive advantages to service providers and end users, making them essential facilities in many private and public conditions. Legislation is in force or in development in Singapore to mandate the usage of hearing loop systems and secure the benefits given to the hard of hearing. The adoption of technology is evolving rapidly and is more widespread around the world.
  • The hard-of-hearing community is increasingly aware of the resolutions available to aid them, expanding end-user demand for assistive listening solutions.

 

Why are hearing loops necessary?

 

According to data, individuals with hearing loss in Singapore are estimated to be around 500,000.

We have been providing comprehensive solutions for practically any assistive hearing application. We desire to make a genuine difference in the quality of life of hearing aid users and are committed to delivering the very best systems for installers, facilities managers, and specifiers.

 

"Simply increasing the volume does not help – it's all about separating the signal from the noise."

How Does an Infrared Hearing System Work?

Audio Video Room

What is an infrared (IR) hearing system? IR hearing system is an assistive audio system to communicate with deaf and hard-of-hearing people. It is a popular option for an induction loop system. A standard system consists of an infrared radiator (transmitter), infrared listening receivers, and an audio source.

 

Receivers are usually available at the front desk of the venue, so it may be advisable for hearing aid users to contact a venue before visiting and to guarantee that staff is well-versed in how Infrared systems operate.

 

How do they work?

Here’s how an Infrared hearing system works in a specific venue:

 

  1. The infrared system (IR) input can be from a sound system, a microphone, or another audio source. They each create an electrical signal which possesses the audio input.
  2. This signal is sent to the modulator, which prepares the audio signal for the succeeding infrared (IR) transmission.
  3. The processed electrical signal is sent to the radiator. The radiator light-emitting diodes deliver the (invisible) infrared light and cast it into the room.
  4. Wireless receivers recast the infrared light signal into an electrical and audio signal (often to a personal induction loop used by a hearing aid wearer).

 

There's no limitation to the number of receivers who can utilize the system. Most IR systems are single-channel and operate on a radiator with an integrated modulator.

 

The most manageable method to consider infrared radiators is to consider them as floodlights of invisible light. There are radiators in various sizes depending on the scope of coverage and the number of channels needed. In most applications, multiple radiators guarantee even light coverage, so the user doesn't experience blind zones.

 

How can we help?

The Listening Lab is the fastest-growing audiology retail chain in Southeast Asia. Our Hearing Enhancement Systems help the average deaf or hard-of-hearing person use hearing aids to hear much better in a public environment. This is because signal-to-noise ratios increase when using a hearing enhancement system.

Hearing Loops: Are They Better than Infrared or FM?

Audio Video Room

Frequency modulation (FM), like in radio and Infrared (IF), similar to a TV remote, has been the traditional form of assistive listening and communication for many years. Both systems are inexpensive compared to a loop system, but neither gives a satisfactory experience like a Loop System.

 

So what makes a loop system unique in terms of assistive listening? Here's something most clients need to understand:

 

"Some places have told us that they already have a loop system. There is some misconception in many venues. Usually, we were notified that there was already a loop system. However, they were referring to an individual neckloop worn around the neck that functions with t-coils.

These neckloops are connected to the FM or IR system in the room. The sound via these neckloops is often inadequate to static over the radio waves. The loop "wire" is below the hearing aid/t-coil; the result is most often sounds coming and going because there is a "null" when one is over a loop wire. This is because sounds bounce from the neckloop rather than directly to the hearing aid."

The misconception on Hearing Loop is that these installations are identical. They are not.

Understanding hearing loops

The user walks into the venue, turns on the t-coil set on their hearing aid, and appreciates the event, production, or discourse. The sound is sent from the loop directly to the hearing aid with no background noise, ambient noise, reverberation, or static.

 

Most users mention that they hear the speaker as though it is right in their heads, and the sounds are more audible and crisp. And they would be accurate since the loop transmits the sound straight to the hearing aid.

 

A hearing loop system does not need a headset or neckloop for the t-coil-equipped hearing aid user. The loop system benefits the user's hearing aid.

About FM or Infrared Systems

FM (radio frequency) and Infrared (IR) have been the conventional forms of assistive listening for a long time. Both are relatively reasonable compared to a loop system. However, neither FM nor Infrared systems provide the user with a quality experience.

 

When using an FM or Infrared system, the user must take off their hearing aids to wear a headset which most people do not want to do. There are battery issues, sanitary concerns, and static feedback from using them. The user has to take the time and struggle to return the headsets from the organizers.

 

Both FM and Infrared boost the sound, while hearing loops provide the sounds that the users need and adjust to their liking.

 

One more thing about neckloops since more hard-of-hearing users are elderly; there might be issues with pacemaker users. If one has an insulin pump, pacemaker, or other medical device, manufacturers advise against using neckloops for fear of interference with the current device. Venues within a hearing loop field do not pose a risk. Only having the magnetic field close to the pacemaker might cause a potential issue.

 

Conclusion

 

Now that you understand the different installations, we can proudly propose that hearing loops are better venue options. Hearing loops are the future of assistive listening, and we can also provide the necessary service for your venue or location. Although FM and Infrared technology are viable solutions, we highly recommend hearing loops.

Where are Audio Induction Loops used?

Audio Video Room

We have discussed why Hearing loops or assistive listening technologies are a requirement in new buildings and renovations. These hearing loops help transmit to those with hearing loss by sending sound sources directly and removing the background noise. Further reading: How loop systems work?

What is a Hearing Induction Loop?

A hearing loop (often called an audio induction loop) is a unique sound system used by people with hearing aids. They produce a signal that connects directly to a Telecoil-enabled hearing aid, enabling people with hearing loss to listen to clear, intelligible sound regardless of the background noise or the distance to the sound they want to hear.

Where can induction loops be used?

Hearing loops can benefit those hard of hearing in multiple environments, from large venues such as theatres and conference rooms to teaching areas, meeting spaces, and one-to-one transmissions such as reception desks and ticketing counters. They are the best sensible solution to help hearing aid users in public spaces.

 

Where can hearing loops be used?

  • Work: Meeting and conference facilities, desks, and offices
  • Schools:: Lecture halls, classrooms
  • Transportation systems: Trains and bus stations, airports, and transport networks, elevators, help points, car park access points
  • Vehicles: MRTS and LRTs, Taxis and private cars, minibusses, coaches, maybe boats.
  • Venues: Movie Theatres, cinemas and concert halls, stadia and sports venues, places of worship, conference and lecture halls
  • Point-of-Service: Counters, intercoms and entry phones, help points, and drive-through restaurants.
  • Safety: Public areas, voice alarm systems
  • Home: TV rooms, phones, individual car systems

 

Hearing loop systems are not suitable if:

  • There is significant background noise, which will decrease the effectiveness of any assistive listening system.
  • There is no sensible way to install the loop cable
  • There is no clearly defined, intelligible audio source
  • Electrical devices such as electric guitars or bass guitars are used within the area surrounded by the loop.

How do you specify an induction loop system?

Specifying which loop system is needed has traditionally been worked out by the area size. However, area size alone is not the exact condition to base specification. A professional must consider a variety of factors to specify a hearing induction loop system, such as:

  • Size of the site where it will be situated to define which type of driver is required.
  • Is there magnetic background noise? Electrical equipment and mains wiring can generate interference with hearing aids using the 'T' setting.
  • Is there surrounding metal in the infrastructure of the building which could impact the loop signal?
  • Ensure the loop signals do not overlap if there is more than one induction loop installed, as this can comprise privacy.
  • Users' head positioning, standing, and seating arrangements must be considered when positioning the induction loop aerials.

Using a user-focused method founded on each area's requirements will specify and provide a loop system with a faultless listening experience.

What is a Hearing Loop?

Audio Video Room

Hearing loss is quite common in Singapore. It affects as many as 360,000 persons, and with the aging population, it is expected to increase. Now, more than ever, there are more hearing aid users, as 1 in 11 Singaporeans have hearing loss.

 

Attending huge events and conferences is daunting as a hearing aid user because listening to and understanding the speakers can be difficult. The great news is that Singapore's Building and Construction Authority (BCA) implemented the Code on Accessibility for Buildings (2013).

 

It means that part of the requirements for this code required new buildings and buildings undergoing A&A works (Additions & Alternations) to install with Hearing Enhancement Systems.

 

The Hearing Enhancement System by the Listening Lab provides solutions for buildings and structures, one of which is the installation of the Hearing Loop.

How does a Loop System work?

A hearing loop (often called an audio induction loop) is a unique sound system used by people with hearing aids. They produce a signal that connects directly to a Telecoil-enabled hearing aid, enabling people with hearing loss to listen to clear, intelligible sound regardless of the background noise or the distance to the sound they want to hear.

 

Hearing Loops function by creating an alternating magnetic field at audio frequencies, which provides an input signal for a Telecoil-enabled hearing aid, cochlear implant, or handheld receiver.

 

A common place to encounter an area coverage loop facility is a conference room. As many as one in every six people experience hearing loss. The most common hearing loop system is a perimeter loop, where the cable is laid around the room's perimeter to cover the entire area.

 

Hearing Loop

 

Loop System process in a conference room:

  1. The speaker uses a dedicated handheld microphone to capture their voice. The signal is transferred to the amplifier when the sound source is captured.
  2. The amplifiers' current delivered to the loop system creates a magnetic field that transmits an audio frequency. International standards stipulate field strength and consistency throughout the listening area.
  3. The magnetic field induces a current in the Telecoil, which is then translated into audio by the hearing aid, transferring sounds directly to the ear canal using the hearing aid's speaker.

What if my building is a modern building containing many metals?

Building owners can't always use a perimeter loop around a room that contains metal because the hearing loop's magnetic field absorbs sounds. Such issues can be resolved using modern design tools and loop layouts that address magnetic field degradation and signal spill.
