Correctional staff face a combination not seen in most workplaces: sustained noise in hard-surfaced housing units where sound reflects rather than absorbs, alarm tones, and concentrated impulse exposure at firearms qualification. Assessments built around a factory model of steady daily exposure tend to underestimate the qualification component badly.
Temporary threshold shift after impulse noise can persist beyond a shift. An audiogram the morning after qualification either records a shift that is not permanent, or - worse, if it is a baseline - permanently depresses the line every future test is measured against. We need the qualification calendar before we schedule anything.
A facility does not stop. We run across shift changes including handover windows, because catching officers at relief works and asking them to attend on a rest day does not. That usually means several shorter visits rather than one long day, and we plan for it rather than treating it as a problem.
Baseline and annual audiograms with calibration dates attached, shift comparisons computed and shown, notification records where a standard threshold shift is confirmed, and clear separation between what belongs in a confidential medical file and what belongs in a programme record.
