What works in hospitals, clinics and pharmacies, where a misheard word can matter most?

Why it matters

Health care depends on spoken exchanges at the reception desk, in the consulting room, at the pharmacy counter and at the bedside, and much of what is said there is private. The authors of an independent 2026 study of 33 Toronto hospital staff and volunteers, funded by hospital research and student research programmes, write, citing earlier work, that hearing loss affects at least two-thirds of hospitalised older adults¹. Local health watchdogs in England have recorded patients unsure whether they had been called in the waiting area, staff commands during MRI and CT scans that patients could not hear, and people who relied on family or friends to communicate and felt they could not keep parts of their medical history private^2,3.

This question covers what a hospital, clinic or pharmacy provides: counter and room loops, portable loops and, at the bedside, personal amplifiers. Amplifiers count here only as an aid the venue lends for the visit or stay, as in an emergency department trial and a hospital's personal hearing sets^4,2; patients' own hearing aids and personal devices are outside this site's scope. Ticket windows and service counters in general are covered in Can Auracast serve ticket windows, service counters and reception desks?.

What the evidence shows

What the rules require

• United States. Under Section 1557 of the Affordable Care Act, the health programs of recipients of federal financial assistance, among other covered entities, must communicate as effectively with people who have disabilities, including companions, as with others, and must provide auxiliary aids where needed, free of charge, in a timely manner and in a way that protects the person's privacy and independence; the rule lists assistive listening devices and systems among the aids⁵. It applies the ADA Title II standards for state and local governments, which give primary consideration to the aid the person asks for^5,6. Under Title III, pharmacies, professional offices of health care providers and hospitals are places of public accommodation⁷; they should consult the person whenever possible, the final choice of aid is theirs provided it results in effective communication, and aids must protect privacy and independence⁸. None of these rules names a type of assistive listening system or a particular desk, room or counter^5,6,8.
• England. Organisations providing publicly funded NHS care or adult social care must have regard to NHS England's Accessible Information Standard, which describes how to identify, record, flag, share, meet and review people's communication needs. In the regulator's account, meeting needs can include a communication professional such as a British Sign Language interpreter, and help from staff to lip-read or use a hearing aid; the Care Quality Commission considers the standard in its assessments and may take action where needs are not met, and services outside the standard must still make reasonable adjustments under the Equality Act 2010. The regulator's page names no listening system⁹. England's building guidance expects any reception point to have a hearing enhancement system, giving an induction loop as the example¹⁰.
• NHS premises. For the primary care and community health buildings it develops or redevelops in England, NHS Property Services requires a fixed loop in all waiting areas, receptions and large meeting rooms, and portable loops "for transportation to private areas during consultations/examinations", one for each reception desk¹¹.
• Small loops. The international loop standard covers small loops for communicating with a listener close by, naming ticket-counter and portable systems among them¹². An academic summary written before the 2014 edition was adopted in Germany reports, for counters, a field of at most -20 dB where other customers wait; this figure has not been checked against the full standard¹³.

What sites have, and what checks found

• Hospitals. At University Hospital Southampton in 2017, two volunteers with hearing loss found the main reception loop working and known to its staff, after it had been reinstalled; of four reception loops checked in clinical areas, one worked. They asked for a named person responsible for loops, staff training, regular tests, reception loops left on whenever reception is open, and new loops at receptions including the emergency department¹⁴. At Royal Cornwall Hospital in 2015, the local watchdog found the updated main reception loop working "but not as well as it should be": with a clip-on lapel microphone the sound reaching the hearing aid was poor, and with the background noise the loop "almost becomes useless". Outpatients had a similar problem, its loop sign was hidden behind a box, and staff at both reception desks visited were not suitably trained to use the loop².
• GP surgeries. Lay audits of seven Eastbourne surgery sites in 2023 found loops at four; three of the four reported that staff would know how to check the loop was on and working, one had procedures for regular checks, and one site had a portable loop for one-to-one discussion¹⁵. In the statutory watchdog Healthwatch Bucks’ self-selected survey and focus groups with 90 Deaf, deaf and hard of hearing people in 2023, 1 of 85 respondents named a hearing loop as the main way they communicated inside the surgery, against 56 who named speech and 11 lip reading. The watchdog reports that people whose hearing aids can use a loop preferred one to depending on lip reading alone, and that not every surgery has a loop and not all staff know where it is kept or how to use it³.
• Pharmacies. On visits to 48 pharmacies in Hackney, London, in April 2022, made on dates the pharmacies were not told in advance, nine had a loop, and staff at two of those were unaware of it or did not know how to use it; 39 were advised to install one and train staff¹⁶. In an independent academic survey of 130 community pharmacists in Poland in 2025, whose authors state that it received no external funding, 123 of 129 (95.3%) said their pharmacy uses no tools to help communication with hearing-impaired people, a question that grouped printed materials with an "induction loop station - sound amplifier"; 52.3% said their training had definitely not adequately prepared them for these patients¹⁷.
• How the checks were made. None of these reports describes measuring a loop's field: the volunteers and watchdogs judged loops by listening or recorded what was present^14,2,15,16.

Personal amplifiers lent at the bedside

• Effect. In an independent academic randomised pilot in a veterans’ emergency department, with funding not stated in the abstract, 133 patients aged 60 and over, likely to be discharged home, who said they had difficulty hearing or scored 10 or more on a hearing handicap questionnaire, were split between a personal amplifier for the visit and no device. With the amplifier, 75% agreed or strongly agreed that they understood what was said without effort, against 56% without; 75% against 36% said clinicians explained their presenting problems; and 3% against 9.0% returned to the emergency department within three days. These are descriptive results from one site, almost all participants were men, and only the abstract was read; the authors call for a larger, more definitive trial⁴.
• Use in practice. Royal Cornwall Hospital had placed 50 personal hearing sets around the hospital for patients without hearing aids, and the watchdog suggested adding a loop option so that hearing aid users could use them too². At Mount Sinai Hospital in Toronto, 33 staff and volunteers interviewed in 2023 saw amplifiers as valuable but underused: amplifiers got used when one was already at the bedside and working, but devices were kept out of sight, had to be searched for on other units or went missing, and nobody was clearly responsible for batteries, headphones or repairs¹.

Cleaning lent devices

• In hospitals. The Cornwall watchdog asked the hospital to consider "cross contamination and infection control" of its personal hearing sets². Toronto staff described no uniform hospital-wide system for retrieving, cleaning, storing and returning amplifiers, and one geriatrician asked whether there were cleaning procedures staff needed to know about¹.
• A written loan procedure. Sinai Health’s January 2025 procedure requires staff to sign devices out through Interpreter Services, also locates PocketTalkers on named units, and makes the requesting unit responsible for cleaning and returning them. It specifies wipeable skins or Virox wipes and additional cleaning through Sterilizing and Processing when needed; this documents a procedure rather than whether it is followed¹⁸.
• General guidance. A 1999 report to the US Access Board lists hygiene after return among the duties of the person who lends receivers, such as wiping foam cushions with an antiseptic solution and replacing disposable ones¹⁹. Listen Technologies, a receiver maker promoting its own wipes, advises disinfecting equipment after each use, specifies at least four minutes of wet contact for those wipes, and warns that alcohol- or bleach-based products may damage casings, screens and labels²⁰. In a self-selected survey of 1,519 people with hearing loss by an advocacy committee, with funding not stated, about assistive listening in public places generally, complaints included unhygienic headsets²¹.

Privacy at the desk and in the consulting room

• The duty. US rules require aids to be provided in a way that protects the person's privacy and independence^5,6,8.
• Design. NHS Property Services lists privacy at the reception desk, with waiting seats not too close to the desk, and an interview room next to reception among its design points; it requires glazed screens, where fitted, to let patient and receptionist communicate easily without blocking sound, and requires portable loops for private consultations¹¹. The Eastbourne checklist asked whether doctors have portable loops for patient appointments, "allowing confidentiality"¹⁵.
• Pharmacies. Healthwatch Hackney describes the NHS requirement that almost all pharmacies have a consultation room where patient and pharmacist can talk at normal speaking volumes without being overheard. It found some rooms too small or used for storage, with staff saying a private conversation would have to take place outside the pharmacy, and notes that chairs near the counter could create issues with confidentiality¹⁶.
• Spill. Ampetronic, a loop maker, says that outside a simple perimeter loop an audible signal can be heard as far as about four times the room's width away, and offers low-spill designs to contain it²²; the summary of the loop standard gives at most -20 dB where other customers wait at a counter¹³. For Auracast, the SIG advises encrypting confidential content because the signal passes through walls²³.
• Companions. Some Buckinghamshire respondents who relied on family, friends or social workers to help them communicate felt this did not let them keep parts of their medical history private³.

Auracast

• RNID finds that at a reception desk a well-maintained hearing loop still gives people without a smartphone a simpler experience than an encrypted Auracast stream, and asks that desks keep loops until Auracast is equally simple²⁴.
• The Center for Hearing Access marks service counters as "yet to be solved" for Auracast and lists private one-to-one use at service desks and counters among the open needs^25,26.
• An independent University of São Paulo scoping review published in 2026, funded by a FAPESP grant and a PIBIC scholarship, included 17 documents and calls for studies in healthcare settings²⁷.

Where sources disagree

Little published disagreement; the sources mostly describe different parts of the problem. Requirements and practice differ: NHS Property Services requires a loop at every reception and waiting area of the primary care and community health premises it develops or redevelops¹¹, and England's building guidance expects a hearing enhancement system at reception points, giving a loop as an example¹⁰, yet checks at hospitals, GP surgeries and pharmacies found many desks and counters with no loop, a loop that worked poorly, or staff who did not know how to use it^14,2,15,16.

The rules differ in how specific they are. US rules list assistive listening among many possible aids and leave the choice to the provider after consulting the person, with primary consideration of the person's request under Title II and Section 1557^8,6,5, and the regulator's account of England's Accessible Information Standard names no listening system⁹, while NHS Property Services names loops for receptions and consultations¹¹.

On lent amplifiers, the emergency department pilot reports easier understanding with the device⁴, while staff at a Toronto hospital describe the devices as underused¹: the first measured the effect when every patient in the trial arm was given one, the second records staff accounts of routine use. In the Buckinghamshire survey, people whose hearing aids can use a loop preferred one, yet 1 of 85 respondents named a loop as their main way of communicating in the surgery; the same report says not every surgery has a loop and not all staff know how to use one³.

What would settle it

Measurements of loops at hospital receptions, GP desks, consulting rooms and pharmacy counters against IEC 60118-4, including the field where other patients wait, repeated over time. Trials with hearing aid and implant users that compare counter loops, portable loops, lent amplifiers and Auracast for understanding of instructions about medicines, consent and discharge, including the larger randomised trial of lent amplifiers that the pilot's authors call for. Tests of cleaning methods and contamination on lent headphones, amplifiers and neckloops. Surveys of patients beyond self-selected local samples, and the healthcare studies of Auracast that a scoping review calls for. The cited sources show these are missing: the healthcare checks cited were judged by listening or recorded from checklists^14,2,15,16; the only controlled trial cited here is a 133-patient pilot⁴; the patient survey is a self-selected local sample³; hygiene appears only as guidance, a watchdog's concern and staff uncertainty^19,20,2,1; and for Auracast in health settings the cited sources offer a call for studies and an advocate's view, without test results^27,24.

Planning while it is open

• In the US, provide aids free of charge, in time and in a way that protects privacy and independence; ask what the person uses, and under Title II and Section 1557 give primary consideration to the aid the person asks for^5,6,8.
• In England, identify, record, flag, share, meet and review each patient's communication needs, as the Accessible Information Standard describes⁹.
• Fit a loop at reception and in waiting areas, and keep a portable loop at each reception desk to take into consultations, as NHS Property Services requires for its primary care and community health development or refurbishment projects^11,10.
• Clip the counter loop's lapel microphone to the receptionist, or use a different microphone, so that communication is clear, as the Cornwall watchdog asked².
• Name a person responsible for each loop, keep reception loops on whenever the desk is open, test them on a regular schedule, train reception, pharmacy and practice staff to use them, and put clear signs where patients can see them^14,15,16,2.
• Consider lending a personal amplifier for the visit to patients who say they have difficulty hearing, as the emergency department pilot did; its authors call amplifiers a possibly important adjunct that needs a larger trial. Keep amplifiers visible and working at the bedside, give someone responsibility for batteries, headphones and repairs, and record hearing loss and device use in the patient's record^4,1. Where hearing aid users may borrow them, add a loop option².
• Set one hospital-wide procedure for retrieving, cleaning, storing and returning lent devices that takes infection control into account; clean them after each user, wipe or replace ear cushions, and follow the maker's advice on cleaning agents^1,2,19,20.
• Keep waiting seats back from the reception desk, provide a private room next to reception, make sure glazed screens do not block sound, and address counter-loop spill where others wait: Seidler’s summary reports a -20 dB limit, which has not been checked here against the full standard^11,16,13.
• Call patients from the waiting area in person or with a visual display^3,2.
• If Auracast is added, encrypt confidential content, and keep reception loops maintained until joining Auracast is equally simple, as RNID asks^23,24.
