THE PANG FORMULA A Forensic Audit of Decontextualized Acoustic Modeling, Medical Scapegoating, and Timeline Sanitization in Workers' Compensation Determinations Flora Pang, M.Sc., RAUD, Aud (C) β WorkSafeBC Audiologist Advisor Prepared for: Otolaryngologist Consultation β May 27, 2026 Subject Analysis: WorkSafeBC Audiologist Advisor Flora Pang, M.Sc., RAUD, Aud (C) Patient: Mark Thomas Holand β WorkSafeBC Claim #42647461 Prepared: May 20, 2026 CHCPBC Professional Conduct Case ID: 2026-057 FIPPA FOI Request: WCB-2026-0484 INTRODUCTION: THE MECHANICS OF THE FORMULA In the realm of occupational health, clinical curiosity demands that a diagnostic model adapt to the physical reality of the host's environment. An honest assessment begins with the workplace β its geometry, its hardware, its specific acoustic profile β and works outward to the medical evidence. A forensic audit of recent determinations by WorkSafeBC Medical Advisor Flora Pang reveals a rigid, inverted methodology: forcing complex, high-energy physical environments into static, flat-line textbook templates. The physical reality of the workplace is made to conform to the model, rather than the model conforming to the workplace. This investigative report maps the DNA of this administrative shortcut β the "Pang Formula" β across a series of distinct trades and injury profiles, culminating in a comprehensive case study of the Holand file, which adds a fourth dimension to the pattern: the active sanitization of a chronological data trail. The Four Tactics of the Pang Formula An audit of multiple Workers' Compensation Appeal Tribunal (WCAT) records reveals a consistent, predictable formula applied regardless of trade, injury mechanism, or clinical presentation: e The Averages Trap: Substituting a generalized Time-Weighted Average (TWA) to mathematically erase violent, short-duration, or cyclic high-frequency energy spikes. By calculating an 8-hour average, extreme transient events vanish from the data model entirely. e The Symmetry Demand: Asserting that all valid occupational hearing loss must be uniform and symmetrical, completely ignoring directional near-field spatial acoustics. Any deviation from laboratory symmetry is declared evidence of a non-occupational cause. e The Pre-Existing Scapegoat: Selectively weaponizing fragments of a worker's medical history to dismiss the acute physiological impact of a documented workplace hazard β while simultaneously ignoring other pre-existing factors that contradict the denial.
