An eleven-month acoustic and observational study of enforcement without enforcers across 214 suburban rail services
A research poster from the School of Emergent Priorities pairs calibrated sound-logging with structured observation across 214 paired rail services to ask what keeps an unstaffed quiet carriage quiet, attributing an estimated 71% of its 1.8 dB(A) advantage to boarding self-selection and 4% to the 38 enforcement events observed, 26 of them performed by nine recurring passengers. The operator's draft Quiet Coordination accreditation has so far enrolled no passenger ever observed to shush.
