Room size, seating extent, coverage percentage and transmitter-to-receiver distance are different quantities.

[@pro-audito-2025-compat; @aph-2008-parliament-loop-audit; @opus-2025-auraloop; @pro-audito-2026-outdoor]\n\n## Compilation and interpretation\n\n`range.csv` was compiled and independently audited on **2026-10-13** against 26 existing library records and their archived originals. It contains 126 rows: individual hall-test pairs and audited loop areas, field observations, explicit numerical product claims, expert estimates, and attributed venue accounts. The audit added supporting passages and corrected source details in existing records. No new source records or question pages were added.\n\nThe file is UTF-8, comma-separated, with one header row, quoted fields and LF line endings. Import fields as text to preserve partial dates, qualifiers and source identifiers. `not reported` means the source does not provide that item; it never means zero. `not applicable` is reserved for a field that does not apply. No formulas or unit conversions are embedded.\n\n\n### Evidence types\n\n| Value | Meaning |\n| --- | --- |\n| `field measurement` | Instrumented result in an installed venue; here, the Parliament House loop audit. |\n| `listening test` | Reception graded by listening to a test signal; here, the Pro Audito hall matrix. |\n| `field observation` | First-hand reception report without a numerical measurement protocol for spatial coverage. |\n| `manufacturer-reported measurement` | A maker explicitly reports a test or measurement, but the underlying protocol/data are unavailable. |\n| `manufacturer specification` | Maker's stated range or area without a published test establishing it. |\n| `manufacturer estimate` | Maker's predicted change under a stated configuration. |\n| `expert estimate` | Practical estimate in expert guidance without a reported measurement series. |\n| `trade-body claim` | Generic range statement from a trade body. |\n| `trade-body venue report` | A trade body's account of a demonstration or venue experience, without independent coverage measurements. |\n\n### Reading the results\n\n- Independent hearing-loss association Pro Audito's hall workbook contains **53 scored pairs**. The association reports no manufacturer funding; manufacturers lent test products without charge. Nine score 1, eight score 2, nine score 3, eleven score 4 and sixteen score 5. Excluding H8 and J9 as its authors do leaves **51 pairs**, with **16 scoring 1 or 2** and **26 scoring 4 or 5**. Blank cells and row/column averages are not results. Grades 1 and 2 permit some dropouts or artefacts; they do not mean uninterrupted reception. Grade descriptions give approximate symptom distances, not a measured maximum range for each pair. Device labels retain source spellings except the expanded Williams name, whitespace, unknown-firmware wording, and the shortened Starkey Edge model label. Exact cells identify the original names. [@pro-audito-2025-compat]\n- The Government audit by Parliament House's own staff has **31 area rows**: nine assigned to the 80-100% category, three to 20-80%, three below 20%, and sixteen with low base level and excessive attenuation. The last category has no numeric coverage percentage. The Cabinet room is among the nine top grades, but Appendix A31 says it was only partially tested with low-level pink noise and refers to earlier commissioning. Its grade is not a complete measured coverage result from this audit. The general procedure adjusted amplifiers before measurement. These are the audit's signal-coverage grades, not a complete assessment against the loop standard. Measurement dates are unstated; 2008 is the report year. [@aph-2008-parliament-loop-audit]\n- Hall dimensions, seating capacity, percent coverage and transmitter-to-receiver distance are different quantities. Do not convert a 22 x 80 m room into an 80 m range, infer a coverage radius from a seat count, or pool these rows into a technology average. Multiple rows often come from the same test and are not independent replications. [@pro-audito-2025-theatre-aarau], [@pro-audito-2025-compat], [@bluetooth-sig-2025-qr-paper]\n- The outdoor 5G result describes venue-wide internet reception with high delay. Its separate phone-to-hearing-aid row records interruptions after that stage. Neither row measures Wi-Fi range. No spatial Wi-Fi measurement was found in the reviewed library material. [@pro-audito-2026-outdoor]\n- Manufacturer Opus's AuraLoop product page gives a 3 m loop range while its linked manual gives 1.10 m. Both claims are retained; their methods and thresholds are not stated. [@opus-2025-auraloop]\n\nThe table excludes legal coverage requirements, recommended transmitter spacing, loop-design width limits, simulations, overspill outside the intended listening area, installation inventories, operational audits without spatial results, receiver/user capacity and speech scores measured in a room without a coverage test. Repeated generic claims are represented by the more specific primary product source where available. The research note records exclusions and remaining gaps. Refresh by checking the source record and its archived original, preserving earlier dated results when conditions or firmware differ.\n", "rows": [ { "result_id": "pro-audito-2025-compat--b2", "technology": "Auracast", "system": "Starkey TV-Streamer FW: not reported", "setting": "Indoor hall without significant event interference; BERNEXPO Stage, Bern; occupancy not quantified", "distance_or_area": "75 x 57 m hall; 18 m ceiling", "outcome": "Rating 1/5: reception throughout the hall with no or very few dropouts and minimal audio artefacts or distortion.", "receiver": "Starkey Edge FW: not reported", "evidence_type": "listening test", "test_date": "2025-09-25", "source_date": "2025-10-06", "source_date_basis": "publication date", "source_id": "pro-audito-2025-compat", "source_locator": "original.xlsx: Signal Reception - Rating!B2; transmitter B1; receiver A2; scale A13:A17; Signal Reception - Test Setup!B2:B9", "funding_detail": "Independent (Pro Audito Schweiz, Swiss hearing-loss association; no manufacturer funding, test products lent free by manufacturers)", "conditions": "Analog pink-noise input from NTI MR-PRO; walk test monitoring dropouts, jitter and distortion; transmitter placed for greatest distance rather than central coverage; 53 scored pairs.", "limitations": "One hall and one deliberately distant transmitter position; subjective listening grades, not packet-loss measurements or measured maximum distances.
