Auracast, hearing loops, FM, and infrared all solve the same core problem—getting clear sound from the source into the listener’s ears—but they differ a lot in how they work, what they cost over time, and how future‑proof they are. Auri™ by Auracast is the most flexible and future‑ready option, but the “best” system still depends on your venue, users, and regulatory needs.

Quick positioning: when each shines

Environment / Need	Auracast / Auri™	Hearing loops	Digital FM	Infrared
General public venues (theatres, halls, malls)	Best long‑term: scalable, works with phones and new hearing aids.	Very strong now if many users have telecoils; highly intuitive.	Good for guided tours, ad‑hoc events, temporary setups.	Good where audio must stay inside the room (e.g., courts, confidential meetings).
Users without hearing aids	Direct listening with phone or Auracast receiver.	Needs loop receivers.	Needs FM receivers.	Needs IR receivers.
Privacy / containment	Encrypted or restricted channels possible.	Needs careful design; overspill controllable with low‑spill loops.	RF can leak; not ideal for strict confidentiality.	Excellent—signal does not pass through walls.
Transient areas (transport, counters, retail)	Very strong: simple connection, no line of sight, supports both HA users and general public.	Excellent for fixed counters and gates if users have telecoils.	Practical where issuing small number of receivers is fine.	More complex for open concourses due to line‑of‑sight.
Budget & lifecycle	Higher initial for cutting‑edge tech, strong long‑term ROI and flexibility.	Highly cost‑effective, especially in telecoil‑rich markets.	Lower install cost, but receiver logistics add ongoing overhead.	Hardware plus manpower for receivers; best justified where confidentiality is critical.

How each system works (in plain language)

Auracast (Auri™)

Auracast is a new wireless audio standard built on Bluetooth Low Energy (LE Audio) that lets one transmitter broadcast high‑quality, low‑latency audio to many devices at once—no pairing needed. Auri™ packages this into a professional assistive listening system with transmitters, receivers, docking stations, and management software.

Key points:

• Source to broadcast: Audio from a microphone or AV system feeds into an Auri TX2N transmitter (supports mic/line, PoE, optional Dante).
• Broadcast over Auracast BLE: The transmitter sends encrypted or open Auracast streams over roughly a 30 m radius; you can add more transmitters to extend coverage or add zones/languages.
• Devices that can listen:
  • Auracast‑enabled hearing aids and cochlear implants.
  • Smartphones and hearables (earbuds, headphones).
  • Auri RX1 receivers with earphones or neckloops for older telecoil hearing aids.

Practical benefits:

• Unlimited listeners—no hard cap on “how many receivers we bought.”
• Multi‑channel: one space can offer multiple language feeds or an audio description track in parallel.
• Backward compatibility for telecoil users via neckloops, while also serving people with no hearing aids using their own devices.

Hearing loops (Audio induction loops)

A hearing loop uses a loop of cable around a room or counter to create a magnetic field that telecoil‑equipped hearing aids and implants can pick up directly. The listener just switches their device to the T‑coil program and hears the venue audio without extra hardware.

Key points:

• Integrates with existing sound systems (mics, PA, TVs) via a loop amplifier driving the loop cable.
• Excellent speech clarity in defined areas and very intuitive to use for telecoil users.
• Hearing Enhancement Systems by The Listening Lab can design low‑spill multiloops to reduce overspill and preserve confidentiality where needed.

Practical benefits:

• Very simple user experience for telecoil users: “walk in, switch to T, listen.”
• No venue‑managed receivers for those users, which cuts manpower and hygiene overhead.
• Often the most cost‑effective assistive listening option where many users already have telecoil‑equipped devices.

Digital FM solutions

Digital FM systems use encrypted radio signals from a transmitter (connected to a mic or mixer) to portable receivers worn or carried by listeners. Users plug in earphones or a neckloop for hearing aids.

Key points:

• Good for flexible and temporary setups—classrooms, tours, training rooms, or spaces where permanent installation is difficult.
• Digital FM offerings are designed for secure, encrypted broadcast and can be deployed with minimal infrastructure.

Practical benefits:

• Portable and reconfigurable; you can move systems between rooms or sites.
• Works whether or not listeners have hearing aids, as long as they’re given receivers.
• Installation cost can be lower than loop or IR, but you must manage, charge, clean, and track receivers.

Infrared (IR) systems

Infrared systems convert audio into invisible IR light, transmit it into the room using radiators, and receivers worn by listeners convert it back into sound. Receivers can then drive earphones or a neckloop for hearing aid users.

Key points:

• Requires line‑of‑sight from radiators to receivers; strong sunlight or obstructions can affect coverage.
• Signal does not pass through walls, making IR ideal when strict room‑level confidentiality is required (e.g., courts, boardrooms, certain classrooms).

Practical benefits:

• Highly controllable coverage; you can design systems to keep audio inside a defined room.
• Less vulnerable to RF interference than many radio‑based systems.
• Like FM, requires issuing and collecting receivers for each session.

Deep comparison: strengths, limits, and best use‑cases

1. User experience and inclusivity

• Auracast / Auri™
  • Pros: Lets both hearing‑aid users and the general public connect using their own devices or the venue’s receivers, supports unlimited users, and allows easy channel selection.
  • Considerations: Requires Auracast‑capable devices to unlock the “no‑extra‑hardware” experience; we are still in a transition phase where not everyone has them yet.
• Hearing loops
  • Pros: For telecoil users, this is the smoothest experience—no app, no pairing, no receiver, just switch to T‑coil.
  • Considerations: People without telecoils or without hearing aids need loop receivers; awareness of the “blue ear with T” symbol is also key.
• Digital FM
  • Pros: Simple for end users once they have a receiver (volume and channel control); good for structured groups (classrooms, tours).
  • Considerations: Managing receivers becomes harder as group size and frequency of use grow.
• Infrared
  • Pros: Good quality audio and predictable experience in controlled rooms, as long as line‑of‑sight is maintained.
  • Considerations: Users must stay within coverage zones and not block the IR path; again, receivers must be distributed and returned.

Takeaway: If you want the most inclusive and flexible user experience for a mix of hearing‑aid users and general public, Auracast/Auri stands out, especially for venues planning for the next decade. Hearing loops remain unmatched for “walk‑in, no‑extra‑device” simplicity in telecoil‑heavy populations.

2. Installation, infrastructure, and operations

• Auracast / Auri™
  • Integrates with existing AV over analog or Dante, uses networked transmitters, and can be expanded across multiple rooms or zones by adding more TX units.
  • Central management software (Auri Manager) lets you configure channels, names, security, and firmware updates across the system.
• Hearing loops
  • Require careful design around room shape, construction, and metal structures to meet IEC 60118‑4 performance standards.
  • Once installed and tuned, operation is largely hands‑off; no daily receiver logistics for telecoil users.
• Digital FM
  • Minimal infrastructure—typically a transmitter and chargers for receivers; good for spaces where running cables or modifying floors is difficult.
  • Operational overhead is in device management more than infrastructure.
• Infrared
  • Needs strategic placement of radiators to avoid blind spots and to stay clear of excessive natural light.
  • As with FM, receiver management is ongoing.

Takeaway: For permanent public venues that want a “set and forget” backbone, loops or Auracast‑based systems designed by specialists are ideal; FM and IR are strong supplements for special rooms or where installation constraints exist.

3. Security, privacy, and compliance

• Auracast / Auri™
  • Supports encrypted and access‑controlled channels for private or ticketed events; central management helps enforce policies.
  • Bluetooth‑based broadcasts stay in the intended area of coverage, and power levels/antenna placement can be engineered to suit the venue.
• Hearing loops
  • Overspill can be managed through professional low‑spill and phased loop designs to keep audio within intended areas where needed.
• Digital FM
  • Digital FM from professional vendors can provide encrypted or coded channels, but radio propagation makes strict physical containment harder.
• Infrared
  • Naturally “room‑bound”: IR signals do not pass through walls, making IR the classic choice when audio may not leak out of specific rooms.

Takeaway: For strict room‑level confidentiality, IR and carefully designed loops are strong choices. For flexible but controlled access (multiple rooms or events with selective access), Auracast with security features is particularly compelling.

4. Cost, lifecycle, and future‑proofing

• Auracast / Auri™
  • Designed as “future‑proof” assistive listening, aligning with the broader industry shift to LE Audio.
  • While initial investment can be higher than basic FM, it reduces dependence on venue‑owned receivers over time as more users bring Auracast‑enabled devices.
• Hearing loops
  • Often the most cost‑effective per seat in suitable rooms and markets, especially when many users already have telecoil‑equipped devices.
  • Infrastructure (loop cable and amplifiers) has a long service life when correctly designed and installed.
• Digital FM
  • Attractive initial costs and portability, but ongoing receiver management and replacement must be budgeted in.
• Infrared
  • Hardware and manpower costs can be justified where confidentiality is a must, but may be less attractive for general‑purpose spaces.

Takeaway: If you’re planning a venue for the 2026–2035 horizon, a combination of hearing loops and Auracast (Auri) is a strong strategic pairing: loops serve today’s telecoil users, while Auri prepares you for the growing wave of Auracast‑enabled hearing aids and consumer devices. FM and IR remain excellent tactical tools for specific rooms and scenarios.

When to choose what (with examples)

• Choose Auracast / Auri™ if:
  • You’re building or upgrading theatres, lecture halls, transport hubs, or multi‑purpose venues and want scalable, flexible, multi‑channel listening that can serve both hearing‑aid users and the general public through phones and earbuds.
  • You want central management, security, and integration with modern networked AV (e.g., Dante).
• Choose hearing loops if:
  • You have fixed seating areas (worship spaces, council chambers, lecture theatres, counters) and a significant proportion of users have telecoil‑equipped hearing devices.
  • You want a highly intuitive, standards‑based, low‑maintenance system with minimal ongoing logistics.
• Choose digital FM if:
  • You run training rooms, classrooms, tours, or pop‑up events where spaces change and you need a portable, reconfigurable system.
  • You can manage a finite pool of receivers and need a quick‑to‑deploy solution.
• Choose infrared if:
  • You have courtrooms, boardrooms, secure briefing rooms, or cinemas where audio must not leave the room.
  • You can control lighting and sightlines to maintain IR coverage and are comfortable managing receivers.

In practice, many organisations end up with a hybrid: for example, loops or Auracast in large public spaces, IR in a few highly confidential rooms, and FM kits for mobile or overflow use.

Choosing the right partner for your hearing enhancement system can make the difference between a compliant, future‑ready venue and an expensive, underused installation. In 2026, expectations from regulators, building owners, and end users in Singapore are higher than ever, so it pays to know what to look for in a trusted installer.

1. Look for proven expertise in assistive listening

Hearing enhancement is a specialist discipline, not just another AV add‑on. A trusted installer should:

• Focus specifically on assistive listening technologies such as induction loops, Digital FM, Infra‑Red and emerging Bluetooth Auracast solutions.
• Demonstrate understanding of how people with hearing loss actually use these systems, including telecoil (T‑coil) hearing aids, neckloop receivers, and Auracast‑enabled devices.
• Explain clearly when a loop, FM, IR or Auracast‑based solution is more suitable for a given space (e.g. worship areas vs. classrooms vs. courtrooms).

A practical test: ask them to compare induction loops, Digital FM, Infra‑Red, and Auracast in plain language for your type of venue; a competent installer will give specific, scenario‑based answers, not generic sales talk.

2. Check for strong technology partnerships

The most reliable installers are backed by reputable manufacturers and global leaders in assistive listening. This matters because:

• Established manufacturers invest in R&D, compliance, and long‑term product support, which protects your investment.
• Certified or authorised partners get access to training, design tools, and factory support to handle complex projects correctly the first time.

Look for installers who work with:

• Ampetronic for audio induction loop systems and Auri Auracast‑based solutions.
• Bellman & Symfon and Sonova/Phonak for Digital FM systems.
• Listen Technologies for Infra‑Red and Auri Auracast platforms.

When these names appear in an installer’s portfolio, it is a strong indication of technical credibility.

3. Confirm understanding of Singapore regulations and BCA requirements

In Singapore, hearing enhancement is part of accessibility compliance, not a “nice‑to‑have” extra. A trusted installer should:

• Be familiar with the BCA Code on Accessibility and how assistive listening applies to auditoriums, lecture theatres, counter services, transport, and places of worship.
• Advise you on where systems are typically required and how to integrate them with your public address or AV system without disrupting operations.
• Help you document installations for audit and future maintenance, including as‑built loop layouts, coverage diagrams, and equipment lists.

During early discussions, ask specifically how they ensure their designs align with BCA expectations and international standards for assistive listening.

4. Ask about design, testing, and documentation

Good hearing enhancement is designed, not improvised. When you evaluate an installer, look for these telltale signs:

• They request drawings, seating layouts, and floor build‑up details instead of simply quoting “per room.”
• For induction loops, they consider metal reinforcement, spill control, and listening height, and can explain the difference between perimeter loops and multi‑loop arrays.
• They carry out site surveys and, where appropriate, field strength testing to validate coverage and intelligibility before handover.
• They provide user guides, signage recommendations (the international “ear with a T” symbol), and basic training for your team.

If an “installer” is unwilling to talk about measurements, coverage, or post‑installation testing, treat that as a red flag.

5. Review real projects and sectors they serve

Experience in environments similar to yours is one of the clearest signs of a trusted installer. Check whether they have:

• Delivered systems in schools, universities, government buildings, houses of worship, healthcare, transport, or corporate venues.
• Managed both new‑build and retrofit projects, coordinating with architects, main contractors, and AV integrators.
• Implemented different technologies (loop, FM, IR, Auracast) in real‑world combinations where needed.

Case studies that describe the challenge, solution, and outcome—not just photos—are a strong indicator that the installer understands both technical and user needs.

6. Evaluate support, training, and lifecycle mindset

Assistive listening systems are long‑term infrastructure, so you want an installer who will still be there after handover. Signs of a dependable partner include:

• Clear warranties on equipment and workmanship, with defined response times for issues.
• Optional maintenance or periodic testing services to keep systems performing correctly as your venue evolves.
• Willingness to train your staff to operate the systems, manage receivers (for FM or IR), and assist end users.
• Guidance on future‑proofing, such as adding Auracast or hybrid solutions alongside existing loops or FM systems.

An installer that talks about lifecycle, not just installation, is more likely to protect your investment over time.
