Just about everything I've done my whole life has been in noisy environments.I can still hear the refrigerator start up, water running in pipes in the walls, animals outside etc. I can also hear the dehumidifier in the basement and vehicles approaching even over other low noises.
If there is background noise like in a busy room I practically need to be shouted at. I am going to blame that more on shooting guns than saws because my dad had the same issue.
But yeah the tinnitus went away after exposure to saws was stopped. Much like the severe tennis elbow I had from 14-15 went away after I got my 550 and quit limbing with a 16 lb saw.
I shot a lot as a kid, first job was pulling skeet and trap from 14.5-16, and I shot thousands of rnds a yr on leagues. Then dirt bikes, high performance cars, crotch rockets, driving truck for 20yrs, lots of loud music as a kid(mom yelling at me

Forgot about the tractor, burned a couple gallons yesterday hauling wood and grading at the neighbors.countless hours of combine and tractor operation
Also the wood splitter hrs would be something to add I forgot, then the mowing lawns(backpack blower and trimmers), forgot that/those too
Anyone want to do a little shooting lol.
