Huh? Oh, yes, I have. Repeatedly. Many times. I fired handguns, rifles, shotguns, you name it. The damage is cumulative, i.e. you might not notice at first, but you are damaging your ears. Next time, you damage them a bit more. And so on.I have never shot a gun without ear protection. Has anyone here had to do that in an emergency situation? Is it so loud that it can damage your ears the first time? Is it pretty scary? Does adrenaline help you overcome the shock of the sound?
Scary? I'm sorry, I am beyond being scared by loud noises.
Adrenaline has little to do with overcoming the effects of loud noises.
