IV. CLINICAL SIGNIFICANCE AND RELIABILITY OF THE CLINICAL
OPINION

IV.A Symptom Onset and Independent Audiometric Findings

The worker's documented symptoms — unilateral (left) ear pain beginning January 23, 2026,
aural fullness, worsening tinnitus, and sound sensitivity — began within days of the OMC1
exposure described in Part III, and were accompanied by a measured 10 dB threshold shift
at 8 kHz in the left ear (Amplifon Surrey, January 30, 2026) compared to a September 2025
baseline taken four months earlier. The worker submits this represents new, measurable
change attributable to the documented exposure, and that the Clinical Opinion does not
adequately account for this shift, the acoustic telemetry described in Part III.B, or the
spatial/directional analysis of the exposure.
