Have read of an airline chap who lost his left ear hearing
Indeed. Now a tale which doesn't involve the denigration of CASA Avmed ...
AN had a 767 captain of older years who, as best I can recall with the passage of years, had a cancerous growth removed from his right ear with total hearing loss on that side. Eventually, he was fitted up with a device in his left ear and an ear trumpet, of sorts, which went over his head and faced centre cockpit. I never flew with him as I wasn't on the 767 but, as best as I can recall, he returned to flying and flew for a considerable period with his accoutrement.
