Signed at the Door, Silent in Row J

A seat-by-seat field-strength survey of hearing loops at 19 suburban cinema screens

A research poster from the School of Continuous Improvement measures audio-frequency induction-loop field strength at 1,140 seat positions across 19 cinema screens at six sites of a single exhibitor, on a sampling lattice and conformance band fixed before the first site visit. 37.0 per cent of positions fall within the ±3 dB band, none of them behind row F, and the median position in the rear third sits 9.1 dB below reference, while every screen carries a current signature in the exhibitor's accessibility register.
