Auracast Is Arriving in Venues. The ADA Rules Still Expect Receivers.

Somewhere this week a volunteer at a town meeting will open the cabinet behind the podium, lift out a plastic receiver on a lanyard, and hand it across while hoping the battery still holds a charge. We have opened that cabinet in schools, courtrooms and sanctuaries in a lot of states, and the receivers are almost always there, because the law says they must be. Whether they work, and whether anyone asked for one last year, are separate questions.

That cabinet now looks dated. Auracast, the broadcast audio capability that rides on Bluetooth LE Audio, has moved out of trade show booths and into working rooms, and building owners now ask a fair question. If a visitor can hear the program in the hearing aids already in their pocket, does the venue still need a drawer of hardware? The answer right now is yes, and understanding why separates an upgrade that holds up from one that quietly fails an accessibility review.

What the rules actually say

Assistive listening in American buildings is governed by the 2010 ADA Standards for Accessible Design, and it is more prescriptive than most owners expect. Section 219.2 requires an assistive listening system in each assembly area where audible communication is integral to the use of the space. The exception is narrow: other than in courtrooms, a system is not required where audio amplification is not provided. A courtroom with no sound system still owes its visitors assistive listening.

Section 219.3 then counts receivers, and the counting is unforgiving. A room seating fifty or fewer needs two. Between fifty one and five hundred seats it is two receivers plus one more for every twenty five seats above fifty, so a two hundred seat house owes eight. Above five hundred the ratio loosens in stages, reaching one receiver per hundred seats over two thousand. At least twenty five percent of the receivers provided, and never fewer than two, must be hearing aid compatible.

Chapter 7 sets the performance. Section 706.2 says required receivers shall include a one eighth inch standard mono jack, and 706.3 says the hearing aid compatible ones interface with telecoils through neckloops. Section 706.4 calls for a sound pressure level of 110 dB minimum and 118 dB maximum with a fifty decibel range on the volume control, 706.5 sets a minimum eighteen decibel signal to noise ratio for internally generated noise, and 706.6 limits peak clipping to eighteen decibels relative to the peaks of speech. The research the Access Board commissioned behind those numbers also recommended one neckloop per four air conduction receivers, and kept returning to installer competence as the real variable.

What Auracast changes

Auracast works differently from the technologies the standards were written around. An induction loop pushes a magnetic field through wire laid in a floor or ceiling, picked up by the telecoil inside a hearing aid, while FM and infrared systems send a signal to a receiver the venue hands out. Auracast broadcasts digital audio that any compatible device in range can tune into, with no pairing handshake and no limit in practice on how many people listen at once. The Bluetooth SIG, which publishes the specifications, frames it as a next generation assistive listening system and notes that loops have long struggled with cost, audio quality, signal spill into neighboring rooms, and privacy.

The supporting pieces arrived faster than most of us expected. Listen Technologies and Ampetronic put their Auri system through Bluetooth qualification in January 2025, describing it as the first complete assistive listening solution built on Auracast. Google announced in March 2025 that Android had added Auracast support, starting with Samsung Galaxy handsets on Android 15 with One UI 7 and with Pixel 9 devices on the Android 16 beta, where a listener can join a broadcast by scanning a QR code. The Bluetooth SIG keeps a running list of venues already broadcasting, from the Sydney Opera House to the University of the Arts London and churches in the United States. Henry Wong, its director of market development, put the position plainly last year: "Venues should begin integrating Auracast broadcasts into their infrastructure today."

The need is substantial. The National Institute on Deafness and Other Communication Disorders reports that roughly fifteen percent of American adults, about 37.5 million people, report some trouble hearing, and that about 28.8 million could benefit from hearing aids. The World Health Organization projects that nearly 2.5 billion people will have some degree of hearing loss by 2050.

The exception that has not caught up

Here is the detail that catches owners out. The Bluetooth SIG argued in May that Auracast is ADA compliant, and on that narrow question it is right, because the standards describe performance rather than naming a technology. The receiver counts are a separate obligation. Section 219.3 does contain an exception that waives the hearing aid compatible count, but it applies only where all seats in an assembly area are served by an induction loop, and Auracast did not exist when that sentence was written. Pair that with 706.2, which requires a physical headphone jack on provided receivers, and a venue that installs Auracast and empties the cabinet has reduced its compliance rather than improved it.

There is a practical reason too. The Center for Hearing Access, which tracks hearing access standards, estimates that around ninety five percent of people wearing hearing instruments today own a model without Auracast, and notes that no hearing aid or cochlear implant yet offers direct single button access to a broadcast, so most listeners need a phone in the middle. Broadcast alone serves the minority with new devices and nobody else.

Two standards still in flight

Two documents will settle much of this, and neither is finished. The European Federation of Hard of Hearing People reported in March that IEC 63087, a technology neutral framework for assistive listening devices and systems, was expected during 2026, while IEC 60118 17, covering wireless audio broadcasting to hearing aids in the 2.4 GHz band, was expected around 2027. The Center for Hearing Access puts that one in December 2027 and expects it to set latency limits, sound quality and connectivity requirements. Until it lands, nobody can certify that an installation performs as an assistive listening system, since Bluetooth qualification confirms only that a product may carry the Auracast trademark.

What a careful installation looks like now

The most useful document published this autumn is a playbook for theaters and live performance venues that RNID, the British hearing loss charity, released on October 14 with support from GN Hearing. It was written for British venues, but the engineering travels. Cover the whole audience area rather than a favored block of seats, and run a second speech broadcast wherever receivers are collected. Test at full capacity, not in an empty room, because an audience absorbs radio energy and sound alike. Confirm that the audiovisual contractor has commissioned Auracast before and can investigate radio frequency interference. The playbook also gives real attention to latency, since streamed audio and the sound from the loudspeakers do not reach a listener at the same instant, which is uncomfortable for anyone still hearing the room through their hearing aid microphones. We would add signage saying what the room offers and how to tune in, plus a written record of what was installed and what firmware it runs.

How we would phase it

For most buildings the sensible path is additive. Keep the loop, FM or infrared system maintained, bring Auracast in alongside it, keep the receivers the standards require, and let the broadcast serve listeners whose devices support it. The Center for Hearing Access is explicit that no site has to tear out an existing system and that these technologies can coexist for years. Venues handling this well treat Auracast as a second path to the same audio rather than a reason to stop supporting the first, and when IEC 60118 17 publishes they will already own the transmitter, the coverage design and the staff habits.

If you run an auditorium, a council chamber, a courtroom, a house of worship or a conference center and are not certain what your assistive listening system actually delivers, we are glad to measure it, tell you where you stand against Section 219 and Section 706, and price out what adding Auracast would involve.
