e Chronological Sanitization: Using hidden, archaic source benchmarks from completely different eras and environments, while actively scrubbing the dates from final reports to project a false veneer of modern, applicable scientific authority. SECTION |: THE ADMINISTRATIVE PRECEDENTS To understand how the formula is deployed against a modern OMC1 classroom environment, one must first examine how it handles heavy industry, acute barotrauma, and emergency response — the occupations where the acoustic hazards are mathematically undeniable. Precedent Case A: The Heavy Fabrication Welder (WCAT A1801216) A veteran industrial metalworker presented with distinct bilateral sensorineural hearing loss following decades of heavy fabrication exposure at a steel foundry and pulp mill from 1964 to 1998. Audiometric testing confirmed bilateral loss consistent with known noise exposure. WorkSafeBC referred the file to Flora Pang for a clinical opinion. The Pang Methodology Applied: The Advisor utilized a standardized macro-exposure decay model designed for steady, continuous background noise. She concluded that the worker's documented bilateral sensorineural hearing loss "could not be attributed to his British Columbia hazardous occupational noise exposure," citing the hearing loss pattern as inconsistent with known characteristics of noise-induced loss. She attributed the loss to "causes of unknown origin present in the general population." The Clinical Flaw: The Advisor completely decoupled the diagnosis from the physical environment — a heavy fabricating shop defined by volatile impulse noise: sledgehammers striking structural steel, pneumatic riveting, carbon arc gouging. Impulse noise delivers near-instantaneous kinetic shockwaves straight to the delicate stereocilia before the middle ear's acoustic reflex can physically engage to protect the cochlea. Treating an environment of hammer strikes as a uniform, flat background average is a fundamental failure of acoustic physics. WCAT Vice Chair Lyall Zucko allowed the appeal, giving greater weight to otolaryngologist Dr. Dumper's opinion, which correctly identified the industrial audiograms as showing a "classic boilermaker's notch" consistent with hazardous occupational noise exposure. The WCAT explicitly found Ms. Pang's opinion inadequate and overturned the denial. Precedent Case B: The Ruptured Eardrum and the Scapegoat Tactic (WCAT A1802828) A worker suffered an acute right eardrum perforation and immediate hearing loss when a workplace technician inserted a custom-moulded earplug too deeply, creating a vacuum phenomenon. The physical mechanism of injury was documented by the worker's own physician on the day of the incident. The worker had a prior history of a childhood tympanoplasty at age 7 — a surgery completed and resolved decades before the workplace incident. The Pang Methodology Applied: Rather than evaluating the raw physical trauma of the insertion event, the Advisor argued that the worker's history of childhood middle ear surgery
