OP, as a fellow subject to aged hearing that also began with loud tools and loud...louder likely music as baggage...
Do you wear aids?
-or-
Would you accept an equalizer that had room correction abilities?
-or-
Both....like me?
...the ’rest of me’ is my own problem....*L* ;)
If traps won't fly, I suspect panels overhead won't get to either.....
An eq up to the task, 'reasonable' cables to knit it in, and a calibrated mic as it's 'ears'.....$1K ought to do it, shopping 'hard' for the sweet stuff if you must...😏
...and you can always 'tweak to taste'....;)
Mho.....If you're 'buttering your beard'.....either wasting it or not performing 'proper'....
My mustache? Yes, Certainly..need not ask.
My beard?
Go to go in that latitude.....a visit to the Hills, perhaps.....
Anywhere Else?
....I trust y'all have That figured out by now.....🙄
