What the system does
Direct audio to the listener’s hearing device.
A hearing loop takes a selected audio source and uses a purpose-built loop driver and conductor to create an audio-frequency magnetic field. A compatible telecoil receives that field and converts it back to sound at the hearing device.

Applications
From one-to-one counters to large listening areas.
Meeting rooms and classrooms
Perimeter or array layouts can cover a defined seating or listening area and integrate with room microphones, DSP and presentation audio.
Explore loop drivers →Auditoriums and lecture halls
Large or metal-rich spaces may require MultiLoop / phased-array design to achieve coverage while controlling loss and overspill.
Read the design guide →Government, healthcare and hospitality
Hearing enhancement can support inclusive communication at service desks, waiting areas, meeting spaces and public-facing facilities.
Universities, schools and training
Lecture, teaching and assembly spaces benefit when the accessibility audio path is designed together with the main PA and presentation system.
Houses of worship and performance spaces
Speech and programme audio can be delivered directly to compatible hearing devices without asking the listener to rely only on room loudspeaker level.
The engineering difference
A hearing loop is not “amplifier + wire”.
Good performance depends on the electromagnetic environment and the actual geometry of the listening area. This is why PNSS treats the loop as an engineered subsystem of the wider professional-audio design.
Background magnetic noise
Electrical wiring, transformers, lighting and other equipment can create interference that affects the listening experience.
Metal loss
Reinforced concrete, raised floors, ceiling grids and other conductive structures can reduce field strength and high-frequency clarity.
Overspill & adjacent rooms
Standard loops can radiate beyond the room. Where adjacent systems, privacy or interference matter, spill control becomes a design requirement.
Loop geometry
Perimeter, counter, cancellation, loss-control and low-spill arrays each solve different coverage conditions.
Audio integration
The correct audio feed, routing, gain structure and priority behaviour must be coordinated with the PA, DSP or conference system.
Commissioning
Field-strength measurement and documented testing provide evidence that the installed system performs as designed.
Ampetronic’s technical guidance specifically advises against choosing a loop driver by floor area alone. Site geometry, metal loss, loop topology and current requirement must be considered together.
Selection logic
Which loop architecture fits the space?
| Project condition | Typical design direction | What PNSS checks |
|---|---|---|
| Reception / service counter | Localised counter / overspill loop | User position, counter material, microphone/intercom source and field localisation |
| Simple room with manageable metal loss | Perimeter / boundary loop | Room dimensions, aspect ratio, conductor position and acceptable spill |
| Metal-rich or larger room | Loss-control / MultiLoop array | Site metal-loss test, seating area, available installation plane and driver current |
| Adjacent rooms or confidentiality | Low-spill / phased array | Horizontal and vertical spill, neighbouring loops and listening-area boundaries |
| Retrofit project | Site-dependent | Existing floor/ceiling finishes, cable route, access restrictions and system integration |

Presentation / collaboration environment
The issued Ampetronic Loopworks design prepared for PNSS used an MLD5 low-spill MultiLoop for a 14.4 m × 6.1 m area with reinforced-concrete construction. Two overlapping arrays, each with six segments, were specified to manage metal loss and control spill.
Reception counter hearing loops
The project equipment schedule included CLD1 compact loop-driver systems for reception desks, with EM195A desktop microphones and local loop coils for one-to-one communication.
Field-strength verification and handover
PNSS carried out on-site testing with an Ampetronic FSM field-strength meter. Signed commissioning records document the MLD5 area system against IEC 60118-4 methodology, while the completed CLD1 counter-loop test recorded a final system pass after testing and fine-tuning.

Customer identity is intentionally withheld from this public case study.
Malaysia & standards context
Plan accessibility requirements early.
Malaysia publishes MS 1184:2014 — Universal design and accessibility in the built environment — Code of practice. Project-specific statutory, consultant and authority requirements should still be confirmed for the actual building and scope. For hearing-loop performance, IEC 60118-4 is the principal international reference used for system commissioning.
PNSS does not treat a web page as a substitute for the architect, accessibility consultant, M&E consultant or approving authority. Tender and compliance wording should be confirmed against the current project documents and applicable Malaysian requirements.
Frequently asked questions
Audio induction loop / hearing loop FAQ.
What is an audio induction loop or hearing loop?
An audio induction loop, also called a hearing loop, T-loop or AFIL system, sends audio through a magnetic field so a compatible hearing aid or cochlear implant telecoil can receive the programme directly.
How does a hearing loop improve speech clarity?
Instead of relying only on room loudspeakers, the loop transfers the selected audio signal directly to the user’s telecoil, reducing the effect of distance, room reverberation and competing background noise.
Do all hearing aids work with an induction loop?
A hearing aid or cochlear implant needs an enabled telecoil or T setting to receive the loop directly. Portable loop receivers can also be provided for people who do not use a compatible telecoil device.
Where are induction loops commonly installed?
Typical applications include auditoriums, lecture halls, conference rooms, meeting rooms, houses of worship, reception counters, service points, ticket counters, help points and other public communication areas.
Can a hearing loop connect to an existing PA or AV system?
Yes. The loop driver can receive a suitable feed from microphones, a PA system, DSP, mixer, conference system or other programme source. The signal path and gain structure should be designed as part of the complete audio system.
Why should a hearing-loop driver not be selected only by room size?
Room aspect ratio, loop layout, required current, metal loss, background magnetic noise, seating pattern and overspill requirements all affect the design. Floor area alone is not enough for reliable equipment selection.
What is metal loss in an induction loop system?
Conductive metal in reinforced concrete, raised floors, ceiling grids and other building structures can weaken and distort the magnetic field, especially at higher frequencies. Site testing and an appropriate loop topology may be required.
What is hearing-loop overspill?
Overspill is the magnetic field extending beyond the intended listening area. It can cause interference with nearby loops and may be undesirable for adjacent rooms or confidential spaces.
What is the difference between a perimeter loop and a low-spill array?
A perimeter loop can be effective for suitable rooms with manageable metal loss and no strict spill requirement. Low-spill or phased-array designs use multiple loop elements to control coverage, compensate for difficult construction and reduce spill into adjacent areas.
Can induction loops be used at reception or service counters?
Yes. Compact counter-loop systems can provide localised one-to-one hearing assistance at reception desks, ticket counters, service windows, intercom points and help desks.
How is an induction loop tested after installation?
Commissioning uses a calibrated field-strength measuring process to verify magnetic background noise, field strength, frequency response and coverage against the project performance target. IEC 60118-4 is the principal international performance standard used for hearing-loop systems.
Does PNSS provide Ampetronic hearing-loop solutions in Malaysia?
PNSS provides project-based Ampetronic hearing-loop solution design, equipment supply, AV and PA integration, installation coordination, testing and commissioning in Malaysia. Final model selection and availability are confirmed for each project.
What information should I send PNSS for a hearing-loop quotation?
Provide floor plans, room dimensions, floor and ceiling construction, seating layout, adjacent-room information, existing PA or AV equipment, intended audio sources, rack location and any accessibility or consultant requirements.
Is a hearing loop the same as FM, infrared or Auracast?
No. These are different assistive-listening technologies with different user-device, coverage, privacy and infrastructure characteristics. PNSS selects the architecture according to the project rather than assuming one technology suits every space.
Has PNSS delivered Ampetronic hearing-loop projects in Malaysia?
Yes. PNSS has hands-on Malaysian project experience involving an Ampetronic MLD5 low-spill MultiLoop system and CLD1 service-point loops, including installation, field-strength testing, commissioning and later diagnostic and remedial support. The customer identity is withheld from this public case study.
Can PNSS test, troubleshoot and maintain an existing induction-loop system?
Yes. PNSS can provide project-based site checking, field-strength and array diagnostics, fault investigation, cabling or system reconfiguration and post-work verification. The exact maintenance scope depends on the installed system and site condition.
Planning a hearing-loop project in Malaysia?
Send PNSS the floor plan, room use, existing audio system and construction information. We can help determine what needs to be surveyed before the equipment schedule is finalised.
