I too am a long time "sufferer" due to an errant fire cracker going off next to my ear some, should I say it, 30 odd years ago. As time has passed it has deteriorated but I still pass the doc's hearing test, even with a jack hammer going off outside his rooms a couple of years ago.
The best part about it is that if there a a million cicada's outside my bedroom, all I do is lie on the non affected side and then I don't hear a thing from the cicadas. Sort of like a natural noise cancelling effect.
Trouble is I can't see the buggers or hardly anything else!
Maybe if I lie on my face........................?
