I have had some high frequency hearing loss since childhood, but pass the FAA whisper test without difficulty. I have had no trouble with my hearing instructing, flying pt 135 and the last 4 years at a regional, but that has all been in intercom equipped aircraft. Looking at moving up in the world and wondering how others with some hearing loss cope in the boeings and etc. without intercoms and with the wind/duct/etc. noise. Do some folks pass the FAA physical and use a hearing aid on one side for cockpit communication? Hints, advice etc. appreciated, and please speak up when you send it! :P
