What works in theatres and cinemas, and what do the rules ask of them?

Why it matters

In the hearing aid manufacturers’ associations’ 2025 UK survey, 38% of the 68 owners who knew they had a telecoil named theatres or auditoriums, more than any other place¹. In an independent academic questionnaire study published in 2025, with no funding declared in the article, 37 adult cochlear implant users rated concerts and movie theatres the second hardest of 12 everyday settings (3.77 on a 1 to 5 scale, against 2.37 for 19 adults with normal hearing)². In a UK survey of 143 people with hearing loss by the social enterprise Ideas for Ears, reported by a trade magazine in 2016 with no funder stated, 94% said their hearing had led to a poor experience at theatres or concerts³.

Cinemas add problems of their own: many auditoriums side by side, soundtracks in which dialogue competes with music, effects and deep bass, and in the US, captioning and audio description duties that can share the assistive listening receivers^4,5,6. This question covers what the rules ask of theatres and cinemas and what venues, listeners and field checks report. Receiver numbers and loan pools in general are covered in How many receivers and neckloops does each code require, and how should a loan pool be run?, infrared in Where does infrared assistive listening work, and where does it fall short?, and keeping a loop beside Auracast in Should a venue keep its hearing loop when it adds Auracast, and can one system serve both?.

What the evidence shows

What the rules ask

• United States: ADA section 219. Each assembly area where audible communication is integral to its use needs an assistive listening system, except, outside courtrooms, where there is no audio amplification. Table 219.3 sets receivers by seating capacity, at least 25% of them (and no fewer than two) hearing-aid compatible; a loop serving every seat waives only that hearing-aid-compatible share. Where several assembly areas in one building are under one management, receivers may be counted from the building's total seats if every receiver works with every system, as in a multiplex⁷. The Justice Department notes that the 1991 Standards asked for receivers for 4% of fixed seats, which the 2010 table keeps for small facilities and lowers for larger ones, and that a sign at the ticket window may replace signs at each auditorium⁸. The International Building Code sets a similar table where states and cities adopt it⁹, and accessible features must be kept in working order¹⁰.
• United States: the 2016 movie theatre rule. The rule adds captioning and audio description duties for cinemas showing digital films "in addition to" the existing assistive listening rules. It requires at least one audio description device for every two auditoriums showing digital movies (at least two per cinema) and lets a cinema count assistive listening receivers it already holds under Table 219.3 if they have at least two channels. The Department had expected most cinemas to have multi-channel receivers; a trade association said many still used single-channel headsets. The Department says it does not intend this to discourage loops for amplification with a different system for audio description, and it describes assistive listening receivers as effective for people who need amplification only. At least one employee who can find, start, operate and address problems with the captioning and audio description equipment must be on site whenever such films are shown⁶.
• England. Building guidance asks for provision for a hearing enhancement system in rooms for performances and films, names induction loop, infrared and radio as the systems commonly used, and asks for the standard symbol where a loop or infrared system is present¹¹. According to a UK theatre consultancy, BS 8300 requires a system covering all audience areas, with provision for at least 4% of capacity in fixed-seat auditoria and 10% in flexible spaces; the standard’s text was not read for this question¹². UK theatre technicians' guidance asks venues to name the system and its type in all advertising, train box office and front-of-house staff, have a named person check the system, post notices when it is out of order, and write into contracts that the loop stays on, because touring companies may ask for it to be switched off¹³.
• Elsewhere. Canada's model code requires a system covering the entire seating area in theatres and auditoria larger than 100 m²¹⁴. Australia's model code, adopted on different timetables by states and territories, requires hearing augmentation in an auditorium with an inbuilt amplification system, with a loop covering at least 80% of the floor area served or receivers available to 95% of it¹⁵. A hard-of-hearing federation reports that the European standard EN 17210 lists performance halls and film venues among the places that should have assistive listening¹⁶. Switzerland's draft standard, not yet valid, asks for Auracast transmitters as well as inductive transmission, and, for receiver systems including Auracast, receivers with neckloops (as a guide, at least 4, or 5% of seats from 100 seats)¹⁷; a Swiss expert reports that the current guideline of 10 receivers or 5 to 10% of the audience is likely to fall to 4 receivers¹⁸.
• Auracast in the codes. The US standards, England's guidance and the Canadian and Australian codes do not mention Bluetooth or Auracast^7,11,14,15; among these cited texts, the Swiss draft names it¹⁷.

Which systems theatres and cinemas use

• UK theatres. In a 2023 review of 465 professional theatres' websites by three access charities, with no funder stated, 364 (78%) were counted as having a hearing loop; the review did not count other systems¹⁹. A theatre consultancy says infrared is widely installed in the UK and radio little used¹², and RNID describes infrared as common in theatres and cinemas²⁰. ATG's UK theatres all offer Wi-Fi streaming to listeners' phones²¹, as does Dublin's Abbey Theatre²². In 2004, mystery shoppers for RNID found no loop in 50% of 75 UK arts venues²³.
• US theatres. A 1,500-seat Texas theatre replaced an infrared system in use for more than 30 years with 72 MHz radio receivers and Wi-Fi streaming, according to Listen Technologies, the maker of the new systems²⁴. An Illinois theatre had replaced its infrared system with a loop by 2012²⁵. In 2012 Listen Technologies’ co-founder wrote that the Kennedy Center uses infrared rather than a loop because it must carry several sources²⁶.
• Cinemas. A UK deaf children's charity says many cinemas have loops at the ticket desk or refreshments counter but tend not to use them in the auditorium, because loop systems "may pick up sound from other screens"; it describes infrared receivers worn like a lanyard as the other system found²⁷. QSC, a US cinema-equipment maker, names loops, radio and infrared as the three methods commonly used⁴. In a 2025 university student study with no funder stated, the researcher reviewed 25 cinemas’ websites, contacted 24 and visited 14 in Southeast Appalachia; preliminary results found personal amplifier devices and closed caption devices the most common accommodations²⁸.
• Auracast. The Sydney Opera House offers Auracast in all its venues alongside hearing loops²⁹. In profiles by the Bluetooth SIG, which owns the Auracast trademark, a 200-seat UK arts centre replaced a failing infrared system with a low-cost Auracast kit after loop quotes of about £10,000³⁰, and a Japanese cinema chain added Auracast beside its infrared system at several multiplexes⁵. A hearing aid makers' association reports a Cheltenham theatre replacing an infrared system parts of which were close to 20 years old³¹, and Listen Technologies and Ampetronic report their Auri system in 20 cinemas of the UK's largest chain³². A US advocacy guide lists movie theaters among the settings where Auracast is still in development³³.

The cinema's hearing-impaired channel

• Where the audio comes from. QSC, which sells cinema processors and infrared systems, describes the hearing-impaired (HI) feed as a "dialog-centric" copy of the soundtrack with reduced dynamic range: cinema processors have long provided an HI output mixing the left, centre and right channels, and many transmitters compress it further. Many digital cinema packages also carry an HI track (track 7), but trailers often lack one and pre-show and live content may not come in a package, so the maker finds the processor's mix the more reliable source. Audio description usually comes on track 8⁴.
• Several channels. Because a loop carries one channel, generally the HI feed, the same maker says audio description is generally carried by radio or infrared, and that infrared generally carries both⁴. A UK consultancy also gives a cinema's hard-of-hearing and audio description channels as an example of infrared's several channels¹².
• Neighbouring auditoriums. The maker says a loop may pick up interference from mains wiring and adjacent auditoriums; a radio listener may choose the wrong channel and hear another auditorium's film, and unencrypted radio can be intercepted outside, "possibly assisting in movie piracy"; infrared, aimed at the screen so that it reflects across the room, stays in the auditorium⁴. A German acoustician says phased loop arrays for cinemas and conference rooms cut the field by about 20 dB about 1 m outside the covered area³⁴, and a measuring-instrument maker gives -48 dB at 1 kHz as acceptable crosstalk between neighbouring loops in critical cases such as cinemas³⁵.
• Hearing aids that switch themselves. The maker says some hearing aids switch to the telecoil automatically in response to a telephone's static magnetic field, which loops and neckloops do not produce, while headphones held over the hearing aids can switch them⁴. In bench notes posted in 2019 by the same engineer, no neckloop switched one user's automatic telecoil; once switched, the user preferred the sound through acoustic coupling, and a local audiologist said most clients use the hearing aid microphone at the cinema³⁶. In Starkey’s study of its own hearing aids, at a simulated looped cinema, 2 of 7 users shown the telecoil and 1 of 7 only told about it switched to the loop programme on their own³⁷.

What venues and listeners report

• Loans per show. A 1,500-seat theatre lends 15 to 20 devices per performance on average, with 50 to 60 requests on some nights, according to the maker of its new system; the figures are not tied to the old or the new system²⁴. A 1999 settlement followed a complaint that a 1,074-seat cinema had 15 receivers; the chain agreed to provide 27³⁸. For audio description, a trade association told the Justice Department its members had signed out at most 1 to 4 devices at any time⁶. A Cheltenham theatre says it was turning people away because it lacked working headsets³¹. Two UK theatre websites asked for audio description headsets to be booked 24 hours or 10 days ahead, and some cinemas ask for infrared receivers to be booked^19,27.
• Staff. In 2004, 7 of 75 UK arts venues were found deaf aware, and RNID asked for training for all arts venue staff²³. US commenters reported cinema visits when no staff knew where captioning devices were kept or how to turn on captioning or audio description⁶, and a 1999 settlement required cinema staff to know where receivers are kept and how to test them³⁸. In the 2016 UK survey, staff speaking clearly and facing the person was the change respondents said would make the greatest single difference, at the ticket office (71%) and with ushers (67%)³. In an account published by hearing aid manufacturers’ association BIHIMA, one UK hearing device user found front-of-house staff eager to help, but the systems seemingly managed or tested by people who "don’t fully understand hearing loss"³⁹. A theatre moving to Auracast held an accessibility open day for audiences and trained front-of-house staff³¹, and the SIG reports that volunteers at a UK arts centre needed about five minutes to learn the Auracast headphones³⁰.
• Listeners' experiences. In the 2016 UK survey, 77% preferred a loop to an infrared or FM system³. An Illinois theatre's manager says its infrared system left many patrons unable to understand dialogue, and that after the loop went in it was thanked at every performance²⁵. A UK hearing device user had two problem-free theatre visits out of 12 in three years, found the T setting with a neckloop on infrared or radio intermittent and poor, and once heard every backstage call through the headphones³⁹. For Auracast, the SIG's profile of a Japanese cinema chain reports users clearly hearing more than 80% of the dialogue in unspecified testing⁵, and a UK theatre a patron moved to tears by the clarity³¹. Wi-Fi users are told to arrive with a charged phone because the battery "could be fully depleted by the end of the show"²¹, and one theatre tells people whose hearing aids lack Bluetooth to remove them²².
• Why venues chose what they did. Venue accounts give different reasons. A Texas theatre followed a reseller's recommendation after LED screens interfered with its infrared²⁴; an Illinois theatre installed its loop after a local audiologist approached it²⁵; a UK arts centre found loop quotes too costly³⁰; a Cheltenham theatre chose Auracast after conversations with its audiences and a local deaf association, with a charitable trust's help with funding³¹; and Listen Technologies and Ampetronic say a cinema chain chose their system for sound quality, low latency, reliability and ease of use³². None of the cited sources is a survey of theatre or cinema operators’ choices.

What field checks found

• Arts venues. RNID's 2004 mystery shoppers found no loop in 50% of 75 UK arts venues; many of the 39% with one did not publicise it²³. In 2009, about 500 reports by RNID campaign volunteers on 210 UK businesses, theatres among them, found the loop not working properly in nearly half of the reports⁴⁰.
• Websites. The 2023 UK review found no access information at all on 15% of theatre websites¹⁹, and the US cinema study found that most cinemas had at least one accommodation but inadequate or no advertising or signage for it; its full results were not yet published²⁸.
• Measurements. In an empty 22 x 80 m Swiss theatre hall, the independent hearing-loss association Pro Audito Schweiz found that one Auracast transmitter reached every seat, but the stream reached the one hearing aid model tested 56 to 58 ms after the transmitter, which the testers judged too long, and distant microphones gave insufficient intelligibility⁴¹. A Swiss advocate's 2005 talk showed a renovated theatre's loop within ±3 dB from 100 Hz to 5 kHz as an example that meets the loop standard⁴². Bench notes from 2012 tests, posted in 2019 by USL cinema-equipment engineer Harold Hallikainen, found neckloops driven by the maker's infrared receiver at full volume well above the 100 mA/m reference, measured at the centre of a neckloop lying on a table³⁶.
• Interference. Patrons of the Texas theatre increasingly heard interference from large LED screens on its infrared system of more than 30 years, according to the maker that replaced it²⁴; the Cheltenham theatre's infrared signal could drop out under the dress circle³¹.

Where sources disagree

Loops in cinema auditoriums. A UK charity says cinemas tend not to put loops in the auditorium because they may pick up other screens²⁷, and a cinema-equipment maker that sells infrared lists interference from adjacent auditoriums and a single channel against loops⁴. A German acoustician describes phased arrays that limit spill as suited to cinemas³⁴, a measuring-instrument maker gives a crosstalk figure for cinema loops³⁵, and the Justice Department says it does not intend to discourage loops in cinemas⁶. On the listener side, a UK survey found most respondents preferring loops in theatres and concerts³, while a cinema engineer reports a local audiologist's view that most clients use their hearing aid microphones at the cinema³⁶.

Infrared. QSC, which sells infrared equipment, presents infrared as the system that stays in the auditorium and carries several channels⁴, and one theatre's infrared served for more than 30 years²⁴. Other venue accounts describe infrared that many patrons could not understand, that failed with age, or that confined users to certain seats^25,31,30, and a consultancy calls its audio lower in quality than a loop's¹². None of these is a measured comparison.

Auracast delay. A hearing aid makers' association writes that lip-readers struggle to detect any delay³¹, and the SIG's profile of a cinema chain reports cochlear implant users experiencing no misalignment⁵. Swiss testers measured 56 to 58 ms to hearing aids in a theatre and judged it too long⁴¹, and a Swiss expert puts total delay through headphones and hearing aids at often about 70 ms against about 40 ms considered acceptable¹⁸. The first two give no figures.

Neckloops and telecoils. The preference for loops in a UK survey³ sits beside one hearing device user's report that the T setting with a neckloop on infrared or radio was intermittent and poor³⁹, and a maker's note that some hearing aids' automatic telecoil switching does not respond to loops or neckloops⁴. Loop and neckloop reception are different paths, and none of these sources measured them in a theatre.

Receivers that serve two purposes. The Justice Department expected most cinemas to have multi-channel receivers that could also deliver audio description, while a trade association said many still used single-channel headsets⁶.

What would settle it

Independent tests in occupied theatres and cinemas that compare loops, infrared, radio, Wi-Fi and Auracast with listeners' own hearing devices, measuring speech understanding and delay; the cited test that measured reception and delay in a theatre was of Auracast in an empty hall⁴¹. Measurements of spill between neighbouring cinema auditoriums with phased loop arrays, and of many Auracast transmitters in one multiplex^34,32. Field audits that test whether installed systems and receivers work on the day, rather than what websites say^19,28. Counts of loans per performance across venues and systems, and of how many listeners connect with their own devices where Auracast or Wi-Fi is offered^24,5. A test of whether the cinema's hearing-impaired mix improves speech understanding compared with the main mix⁴. The text of BS 8300 on auditoria, and guidance in codes on whether Auracast or Wi-Fi can meet receiver requirements^12,7.

Planning while it is open

• In the US, size receivers from Table 219.3 with at least 25% (and no fewer than two) hearing-aid compatible, except that this share is waived where a loop serves every seat; in a multiplex under one management, receivers may be pooled across auditoriums only if every receiver works with every system⁷.
• In a US cinema showing digital films, provide one audio description device for every two auditoriums showing digital movies (at least two per cinema); when replacing single-channel assistive listening receivers, two-channel receivers can serve both duties if they work with both systems⁶.
• In England, provide for a hearing enhancement system in auditoria and check the BS 8300 provisions on coverage and capacity^11,12.
• In a cinema, check the source of the hearing-impaired feed: QSC recommends the processor’s mix because trailers may lack a dedicated track and pre-show or live content may not come in a film package⁴.
• Where loops serve neighbouring auditoriums, design for low spill, for example with phased arrays, and check crosstalk at commissioning^34,35.
• Offer headphones as well as neckloops with receivers, since some automatic telecoils respond to headphones held over the hearing aids and not to neckloops^4,36.
• Train box office and front-of-house staff on what the system is, where receivers are kept and how to test them; name a person to check regularly that the system works; and post notices when it is out of order^13,38,23.
• Test receivers and transmitters regularly (monthly in one settlement) and after any complaint, and keep records^38,10.
• State the system and its type in advertising and on the website, with the kind of headset used, and say whether patrons must bring their own equipment^13,19.
• Write into venue contracts that the loop stays on¹³.
• For Wi-Fi streaming, tell patrons to bring a charged phone and their own headphones and how to join the venue's network^21,22.
• For Auracast, mount transmitters high above the audience, as Graf recommends because a full house can shorten the range, and keep loan receivers with neckloops for listeners without compatible devices^18,17,5,31.
• Whatever the system, put microphones close to the talkers' mouths, and check the timing near the stage^41,18.
