Clear communication is essential in every public space—whether it’s a school gymnasium, church sanctuary, corporate boardroom, or performing arts auditorium. But for individuals with hearing loss, understanding announcements, presentations, or performances can be a challenge without the right technology in place. That’s where assistive listening systems (ALS) come in.
At JD Sound and Video, we design and install assistive listening solutions for facilities throughout New Jersey, Pennsylvania, and Delaware. With decades of experience, we work with the leading manufacturers—Williams AV and Listen Technologies—to ensure your facility not only meets ADA requirements but also delivers an inclusive, reliable experience for every guest.
Why ADA Compliance Matters
According to the Americans with Disabilities Act (ADA), assembly areas where audible communication is integral—such as auditoriums, stadiums, courtrooms, classrooms, or houses of worship—must provide assistive listening systems.
The ADA outlines requirements including:
-
A minimum number of receivers based on seating capacity
-
At least 25% of receivers equipped with hearing aid compatibility (via telecoil or neckloop)
-
Systems that deliver clear, interference-free audio to users
Failure to comply can lead to accessibility complaints, legal consequences, and reputational damage. But more importantly, compliance ensures your facility is welcoming and inclusive for all attendees.
Types of Assistive Listening Systems
There are three main technologies used in modern assistive listening: FM (radio frequency), IR (infrared), and RF/digital systems. Choosing the right system depends on your space, use case, and audience.
🎧 FM (Radio Frequency) Systems
FM systems transmit audio over radio frequencies to dedicated receivers with headphones or neckloops.
-
Pros: Wide coverage, works through walls, cost-effective.
-
Cons: Signal can bleed into adjacent spaces if not managed properly.
FM systems are excellent for gyms, stadiums, and multi-use facilities where long-range coverage is important.
🔴 IR (Infrared) Systems
IR systems use light waves to send audio to receivers.
-
Pros: Contained to the room (no signal bleed), secure for confidential environments.
-
Cons: Requires line of sight; performance can be affected by strong lighting.
IR is often used in courtrooms, theaters, and boardrooms where privacy and control are priorities.
📡 RF/Digital Systems
Today’s most advanced systems use digital RF for clearer sound and flexible integration. Manufacturers like Williams AV and Listen Technologies have introduced modern platforms that:
-
Provide interference-free audio
-
Offer Wi-Fi streaming to smartphones via free apps
-
Support multiple audio channels for translation or event-specific needs
These systems are increasingly popular in auditoriums, houses of worship, and educational facilities where multiple use cases exist.
Integration with Existing PA Systems
An assistive listening system works best when it’s seamlessly integrated into your facility’s public address or sound reinforcement system.
At JD Sound and Video, we:
-
Tie the ALS feed directly into your mixing console or DSP
-
Ensure a clean audio signal without feedback or distortion
-
Configure zone routing so that only the right audio (announcements, microphones, or media playback) is sent to the assistive system
This integration allows your facility to operate one unified sound system while still supporting ADA compliance.
Edge Cases: Gyms, Auditoriums, and Multi-Purpose Spaces
Not every space is simple to equip. Facilities like school gyms and multi-purpose auditoriums require careful planning.
-
Gyms: With their high ceilings and reflective surfaces, gyms are notorious for poor acoustics. FM systems are often the best choice, as they can deliver a direct, intelligible signal to receivers without being affected by echo.
-
Auditoriums: Auditoriums may require multi-channel systems for events, translation services, or live performances. Digital RF or hybrid systems from Williams AV or Listen Technologies excel here.
-
Outdoor Venues: Stadiums and athletic fields benefit from FM or digital RF systems, which provide long-range coverage and allow multiple users to connect simultaneously.
