AJ, one of the best posts I have seen on here. It has always seemed to me likely that given the cost of our shared hobby that it is likely many of us are, shall we say, mature! Much the same in my other dalliance, motor racing. given that demographic, it is inevitable that a large proportion of us suffer age related hearing loss. I do. But worse is my tinnitus = and for that single line 3khz whine I use special HAs that teach my brain to ignore that frequency. It works for me. Thank you for relating your experience. I may try using some and see just what I have been missing.
