I beg to differ with you. I'm 80% deaf in both ears do mostly gun blast, do to thinking if your 16 years old, 6"3" 180lbs, and thinking at the time I was invincible. Yes rifle blast are projected forward but the blast will still deafen you, ask me how I know? What I can't hear you!
In the last 40 years I have spent over $30,000 dollars on hearing aid and still can hear clearly.
I also witness a suppressor for a 338 lupa being shot on a 6.5 creedmoor that sounded just like the ones on the movie screen, couldn't believe how quite.
