Sod that, a quack routing around in my head chances of keeping a class one would be minimal.
To be fair I had spent 15 o so years in heavy industry with grinders and the like all about although I don't have any damage in that range just the 2000-2400 rpm range in one ear and not so much in the other. And I was doing 4-5 hours a day in C172/PA28/PA38's.
It not that bad and falling asleep listening to radio 4 or an audio book is no great hardship. Back ground noise stops it.
