Availability, staff knowledge and listening checks do not establish measured field strength. Grouped results overlap some individual rows, and methods differ: do not pool counts or failure percentages. Reported repairs do not establish a measured retest. [@aph-2008-parliament-loop-audit; @healthwatch-hackney-2023-pharmacy-accessibility; @healthwatch-southampton-2018-central-loops; @chha-2023-yvr-counter-loops]\n\n## Compilation and interpretation\n\n`loop-tests.csv` was compiled on **2026-10-13** from 17 existing library records and their archived originals. It contains 60 rows: 48 individual installations or assessed areas, three checked locations where equipment status was uncertain, and nine explicitly labelled aggregate findings.\n\nThe normal unit is one installation or assessed area, combining its checks in one row. Parliament House has 31 area rows keyed to the audit's A1-A31 references; these are not asserted to be 31 electrically separate systems. Where a source supplies only grouped findings, an `aggregate` row preserves that evidence without inventing individual installations. Filter `row_scope` before analysing individual results. The Scottish total includes its three named rows, and Southampton's overall shop audit includes its named shop examples. Neither totals nor failure percentages should be pooled across these overlapping rows or across unlike methods. [@aph-2008-parliament-loop-audit; @alva-2013-scottish-loops; @healthwatch-southampton-2018-central-loops; @rnid-2009-loop-checks; @chha-2023-yvr-counter-loops]\n\n\nThe file is UTF-8, comma-delimited, with a header, quoted fields and LF line endings. Import as text to preserve qualifiers and multiple years. `not reported` denotes missing information, never zero. There are no formulas, converted units or graph-digitised point estimates. Rows sort by source id and result id, with numeric area suffixes in numerical order.\n\nParliament's coverage categories are the audit authors' classifications after amplifier adjustment, not complete tests of every standard parameter. The Cabinet Room's highest Table 1 grade is retained with its partial-test qualification. Hospital listening quality and bus interference observations are not substituted for field-strength measurements. Hackney and Eastbourne rows describe availability and staff procedures, without proving working audio. Eastbourne's staff-knowledge narrative conflicts with its table; the row preserves that uncertainty. The Southampton therapies loop was not visited and is excluded from the check rows. C6 and C7 have no separately reported listening result, and the chapel's check was separate from the dated main visit.

Updating this table requires re-reading the original, retaining the row's unit and method, and distinguishing an actual retest from a later publication or repair claim.\n", "rows": [ { "result_id": "alfakir-2015-lecture-hall", "row_scope": "installation_or_area", "site": "Unnamed lecture hall", "site_type": "Lecture hall", "country": "not reported", "year": "not reported", "source_year": "2015", "checked": "Field strength at six seating locations", "result": "Authors report loop field strength within +/-3 dB at all six tested seating locations.", "method": "meter", "method_detail": "Contacta Loop-FSM; six randomly chosen seating locations checked before the listener study.
