I went outside Class 1 audiogram limits for professional licences, and was asked by CAA-MED to undertake Functional Hearing Assessments. FHA for ATC had to be done by a 'watch manager' of all people, and for CPL a Cockpit Speech Discrimination Test carried out by an FE. Latter said "well you already wear a hearing aid". "No I don't" said I. "Yes you do", he said, "you wear a headset, just turn up the volume". All rubber stamped, no further action, non-event. I'm only deaf at home now...
