What does each system cost to install and to run over its life?

Why it matters

A venue pays once to install a system and then keeps paying to run it. With FM and infrared, every listener borrows a receiver that the venue must clean, issue, collect and keep charged, while telecoil users in a looped room need none¹. An explanatory note in Canada's model building code lists cost and maintenance among the factors in choosing a system², and a loop seller says site factors can change a loop's installed cost by a factor of two to five³.

This question gathers the prices that sources publish, what running a system involves, and what sources say about why venues buy one system rather than another. What listeners prefer is a separate thread, set out in What do listeners prefer, and how often do they use venue systems?; a buyer's reasons are reported here only where a source gives them^4,5.

What the evidence shows

Published prices

Each figure is given as its source states it, in its own currency and year, unconverted. Most sources do not say whether design, receivers or building work are included, so the figures are not comparable with one another^6,7.

Where the cost rankings come from

• Loops ranked lowest in cost, in a German table. Bavaria's planning guidelines rate equipment and installation cost as lowest for loops (factor 1), about twice that for FM and about 2.5 times for infrared, in a table used with the permission of an engineer from the German hard-of-hearing association¹⁵. That association's planning section says it developed a table with the same cost factors, that the table entered DIN 18041 in 2004 and Switzerland's SIA 500, and that on costs "lediglich qualitative Aussagen möglich sind" (only qualitative statements are possible); its brochure quotes a note in DIN 18040-1 calling a loop generally the most favourable solution in construction and maintenance costs, and was printed with financial support from four companies, among them the loop makers Ampetronic and Univox¹⁶. A US federal advisory committee calls a permanent loop an inexpensive option for jury assembly areas¹⁷.
• FM and RF ranked lowest in cost, in US guidance and maker material. A guide distributed by HLAA's loop programme gives FM the easiest installation and the lowest installation cost, and infrared more cost for very large areas¹. In 2012 the co-founder of Listen Technologies, then a maker of RF and infrared systems, put a typical RF system under $5,000 and infrared under $10,000, with loops "much more" because the loop goes into the floor of the whole venue⁷. The same maker, which now also sells loops, Wi-Fi and Auracast systems, lists RF as budget-friendly and loops as costly and intrusive to install¹⁸. A Wi-Fi maker calls loop installation expensive and labour-intensive and says infrared takes "a lot of time and resources" to install and maintain¹⁹, and a loop advocate writes that the advantages of RF and infrared lie in easier installation and lower installation cost for the venue²⁰.
• Auracast against loops. Two makers that sell both rate Auracast's cost below loops' and its installation as "Minimal", without prices¹⁴. A market note commissioned by the Bluetooth SIG speaks of Auracast's "dramatically lower implementation and support costs", without figures and without saying what they are lower than⁴. Three German hearing-loss organisations state that installing Auracast is in many cases cheaper than a loop, especially in existing buildings, while holding that loops must stay available for the foreseeable future²¹. Pro Audito says a loop plus an Auracast transmitter costs more because two systems are installed, and that an Auracast transmitter with loaned neckloop receivers costs less but often does not work well enough in practice and adds work in training staff and informing visitors²². The Center for Hearing Access says Auracast assistive listening is not "plug and play" and needs skilled installers²³.

What drives a loop's installed price

• The building. In the loop seller's examples, metal loss and future neighbouring loops call for arrays, which cost more in equipment and labour, and concrete sawing costs $2 to $10 a foot or more³. Bavaria's guidelines warn that an amplifier rated for 1,000 m² may cover only about 80 m² to the standard in a real room¹⁵. In Munich's city hall, measurements showed that the gallery loops of two council chambers would interfere and that compensation would not solve it, so the looped areas on both galleries are to be limited⁵.
• Where the cable goes and what feeds it. One firm quoted a town council £1,250 for a floor or wall loop and £2,750 for a ceiling loop with the same microphone, and the other quotes varied with the microphones, mixers and extras included⁸.
• Labour. Australia's infrastructure and transport department calls loops a mature technology whose "Material costs are low with labour usually being the main expense", with the price varying with the area covered; it adds that extending coverage may need a new system and bring costs at some sites, particularly those with overhead wires²⁴.
• Timing. An advocacy group advises installing during a remodel, new build or flooring replacement to cut cost²⁵, and the loop seller says that on a new build with no metal loss a loop can be laid in two to six hours before the floor covering goes down³.

Receivers, batteries, charging and staff time

• Who needs a receiver. Under the ADA, at least 25% of the required receivers must work with hearing aids; where a loop serves every seat this minimum falls away, but the other receivers are still required^26,18.
• Receiver prices and upkeep, as the US government modelled them. In its 2010 analysis the Department of Justice modelled incremental operation and maintenance at 4% to 6% of unit cost a year and replacement every 10 years; these are assumptions about the added receiver requirement, not measured total running costs. It asked operators for their maintenance costs and replacement cycles and found the replies "too general in nature" to use¹².
• Batteries and charging. One maker gives its infrared receivers about 30 hours on AAA alkaline batteries and about 15 hours on its rechargeable pack, which takes up to 9 hours to charge²⁷. An independent Pro Audito Schweiz test of one system, supplied free by its maker with no payment to Pro Audito, gives its Auracast clip receiver about 8 hours of battery life when driving a neckloop¹³, and one maker's Wi-Fi receivers typically charge in 2 to 3 hours²⁸.
• Staff time. A 1999 report to the US Access Board recommended one trained person to issue, check in, charge, listen-test and clean receivers²⁹. A US advocacy group lists receivers for every user, batteries, hygiene and staff time to issue, explain and retrieve receivers among infrared's limitations for operators³⁰, and a theatre consultancy describes a staffing overhead for charging, maintaining and supporting receivers that is higher when more channels are offered¹⁰. The German hard-of-hearing association's table lists an issue and return point at every event for FM and infrared, and for loops only for listeners without a telecoil¹⁶. Australia's infrastructure and transport department states that the logistics of issuing, collecting and cleaning receivers "almost certainly precludes their use in a public transport system"²⁴.
• Auracast and Wi-Fi still need loan receivers. A US advocacy group says receivers with neckloops will be needed for Auracast for the foreseeable future³¹, and three German hearing-loss organisations recommend loan receivers with headphones or a neckloop for people without Auracast over the next few years²¹. A Wi-Fi maker says venues must still provide the ADA's receivers and suggests venue phones with its app and neckloops or wired headphones³², and another says dedicated Wi-Fi receivers are "often required" where laws require receivers²⁸. An industry association counts less shared equipment and fewer hygiene concerns among Wi-Fi's advantages, and advises venues to provide alternative receivers for people without a smartphone³³. One US venue keeps its RF system, with free loan receivers, alongside its Wi-Fi system³⁴.

The question How many receivers and neckloops does each code require, and how should a loan pool be run? sets out receiver numbers and the running of a loan pool in full^26,29.

Maintenance, recommissioning and replacement

• Loops. RNID recommends maintaining a loop every 12 months, and refers venues to an installation partner offering annual maintenance schemes, which gives RNID a 5% donation for each system installed through RNID's referral address³⁵; it asks venues to keep testing and maintaining loops for at least five and potentially nearer 10 years during the move to Auracast³⁶. A German manufacturers' association calls loops commissioned to the standard "praktisch weitgehend wartungsfrei" (in practice largely maintenance-free)³⁷. Bavaria's guidelines require loops to be on whenever the public is present and checked regularly by a trained person¹⁵, and an advocacy group asks installers for warranties, maintenance agreements and staff training²⁵.
• Receiver systems. A 1999 settlement required a cinema chain to test all receivers and transmitters monthly and after any complaint, and to start repairs by the next business day³⁸.
• Infrared emitters and system life. One maker under-rates its infrared radiators by 40% because their output falls by that much after about 8,000 hours of operation³⁹. The same maker reports a Texas theatre whose infrared system still worked after more than 30 years but suffered interference from LED screens, and was replaced with RF and Wi-Fi⁴⁰. A UK arts centre's ageing infrared system had begun to fail, with no spares available, according to the Bluetooth SIG¹¹.
• Wi-Fi software. One Wi-Fi maker states that keeping its servers and other components updated is essential for compatibility with current smartphones and operating systems²⁸.
• Rule changes. When the FCC in 2013 lowered the limit on unwanted emissions from 72-76 MHz devices, at an estimated 1-2% added cost per device, it let installed devices stay in use for the life of the equipment so that venues would not be forced to replace systems they use to meet the ADA⁴¹.

Software, licences and fees

One Wi-Fi maker states that its listening app is free "without any advertisements"²⁸. An Auracast location that registers with the Bluetooth SIG receives a royalty-free, revocable licence to use the Auracast marks, on condition that it keeps a quality level the SIG may test⁴². The sources read give no recurring licence or subscription fee for a venue system of any technology.

Government cost estimates and rules

• United States. The Department of Justice put the net present value of requiring hearing-aid-compatible receivers at minus $25.77 million (costs to facilities of $28.05 million against $2.28 million of benefits to users), and of requiring fewer receivers in assembly areas over 500 seats at plus $273.95 million, at a 7% discount rate in its primary scenario (USD, 2010)¹².
• Australia. A 2022 consultation put the compliance costs of hearing augmentation covering the whole of each public transport vehicle at A$122.6 million substantive and A$1.6 million administrative (real 2021/22 dollars, discounted at 7%), and did not cost the change for stations and stops²⁴. That whole-vehicle option was a proposal: the 2026 amendment kept the 1992 hearing augmentation requirement for installed public address systems⁴³.
• New York City. A 2017 law requires a loop in at least one assembly area of qualifying city capital construction or reconstruction projects with a baseline construction cost of $950,000 or more, exempts reconstructions where the loop would cost more than 5% of that baseline, lets the Mayor exempt up to 20% of the capital dollars concerned each year, and requires the city to publish the cost of new systems⁴⁴. The resulting list gives costs for 365 of its 1,401 entries⁶.
• Minnesota. State law requires loops in qualifying state-funded construction or renovation of public gathering spaces for at least 15 people with a permanent audio system, and the state commission reports that it "has no data about any projects that may have followed the statute"⁴⁵.

Why buyers choose a system, as far as sources show

• Recorded decisions. In Munich's city hall, infrared was planned for a council chamber, which the city describes as secure against eavesdropping and needing no work on the existing floor. For two meeting rooms, a portable system with neckloops was chosen over a fixed radio system that cost about five times as much at nearly the same functionality, after an on-site demonstration to participants who included representatives of the city's disability advisory council⁵. A UK arts centre found loop quotes of about £10,000 "a significant barrier" and ran a low-cost Auracast trial instead, according to the Bluetooth SIG¹¹. An English town council sought loop quotes after a report on the legal duty to provide auxiliary aids⁸, and a Texas theatre installed RF and Wi-Fi on a reseller's recommendation after LED screens interfered with its infrared system, according to the maker that supplied them⁴⁰.
• Rules and public money. New York City and Minnesota require loops in qualifying publicly funded construction and renovation projects^44,45. New York's list shows FM in 996 school entries and loops in 148, most of the loops still in design, bidding or construction, and loops in 152 of the 257 entries outside schools; it does not say why each system was chosen⁶.
• Claims without buyer data. A market note commissioned by the Bluetooth SIG, based on interviews it does not count, names regulation and its enforcement as key drivers, says many US venues fall short of the rules, and suggests that Auracast's lower costs could drive significant change⁴. A 1999 report to the US Access Board described loops as rarely in competition with FM and infrared for new US installations, and said this was unlikely to change unless more people chose hearing aids with telecoils, which only about 30% of US hearing aids then had²⁹. A maker's co-founder names low cost and the ability to carry several audio sources as the two main advantages of RF and infrared⁷, and a loop advocate argues that as more people use loops, their cost per user will fall, without figures²⁰.

Where sources disagree

Sources rank installation cost in opposite orders. Bavarian guidelines and the German hard-of-hearing association put loops first (factor 1) and FM and infrared at about twice and 2.5 times the cost^15,16, while a guide distributed by HLAA's loop programme, a maker's co-founder and the maker's 2023 white paper put FM or RF first^1,7,18. Neither side publishes the data behind its ranking: the association calls its factors qualitative and had its brochure printed with support from loop makers, and the maker's co-founder gives round figures for RF and infrared and none for loops, writing for a company that then sold RF and infrared systems^16,7.

On Auracast, two makers and three German hearing-loss organisations say it costs less to install than a loop^14,21, and a market note for the Bluetooth SIG calls its costs "dramatically lower" without naming a comparison⁴. Pro Audito says the cheaper set-up, a transmitter with loaned neckloop receivers, often does not work well enough and adds work in training staff, while the set-up it prefers, a loop plus Auracast, costs more²²; RNID, and Swiss guidance that relays Pro Audito's advice, recommend both in new buildings where feasible^36,46. None of these sources gives the installed price of an Auracast venue system.

On running costs, a German manufacturers' association calls loops commissioned to the standard "praktisch weitgehend wartungsfrei" (in practice largely maintenance-free)³⁷, while RNID recommends maintaining loops every 12 months³⁵ and two Healthwatch Southampton members with hearing loss found three of about seven listed loops working at one hospital trust; their report gives no separate audit funding⁹. For Wi-Fi, an industry association counts less shared equipment as an advantage³³, while two makers say venues that must meet receiver rules still need to supply receivers or phones^32,28 and a consultancy puts a venue phone at about twice a basic RF receiver¹⁰.

Published loop prices span a wide range: about £100 for a portable loop, or for a counter loop plus installation⁹; $313 to $10,100 for entries labelled counter loop and $300 to $241,117 for entries labelled induction loop in New York City⁶; and, in a seller's examples for a 1,000-seat performing arts centre, $19,899 for the main floor without metal loss against $43,371 with metal loss and the balcony and boxes added³. The New York list does not say what each cost covers, and one council's quotes for the same chamber varied with the microphones and extras included^6,8.

What would settle it

Whole-life cost comparisons of loops, Auracast, infrared, FM and Wi-Fi in comparable rooms, from completed projects, counting design, installation and building work, receivers and neckloops, batteries and charging, staff time per event, maintenance, recommissioning and replacement; the rankings found are relative factors or round figures without data^16,7. Operators' records of maintenance costs and replacement cycles, which the US government asked for in 2010 and did not receive in usable form¹². Installed prices for Auracast and Wi-Fi venue systems. Public cost lists that state what each figure covers⁶. Use counts set against costs, to test claims about cost per user²⁰. A survey of venue buyers and installers on why they chose a system: the sources found give single decisions, rules and claims, not a sample of buyers^5,4. Makers' terms showing whether any venue system carries recurring fees.

Planning while it is open

• Have the site measured for magnetic background noise and metal loss before a loop is priced or designed, and for a retrofit consider a temporary test loop^47,3,16.
• Fit loop work to building work: a remodel, new build or flooring replacement^25,3.
• Get at least two bids after a site visit, and ask for documentation, warranties and maintenance agreements²⁵; compare what each quote includes, since one council's quotes for the same chamber varied with the microphones, mixers and extras included⁸.
• Budget for receivers and neckloops with every technology, including Auracast and Wi-Fi, and for the ADA's hearing-aid-compatible share unless a loop serves every seat^26,31,32,28.
• Budget staff time for the loan pool: one trained person to issue, check, charge and clean receivers, and regular tests of receivers and transmitters^29,38.
• Budget for upkeep and ageing: yearly loop maintenance³⁵, infrared coverage designed from the maker's published patterns, which allow for emitter output falling with use³⁹, and updates to Wi-Fi servers as phones change²⁸.
• Where a loop already exists, consider adding an Auracast transmitter that reuses its microphones, and keep the loop maintained during the transition^21,36.
• Check whether rules tie public money to a technology, as in New York City and Minnesota, and what exemptions they allow, such as New York's for reconstructions where a loop would cost more than 5% of the baseline construction cost^44,45.
