I am sorry you have it so bad.
I live with it of course but it’s the pulsatile part that drives me a little batty. :)
I dont need to be reminded that my heart is beating :)
Is hearing protection something they address now in the military when using rifles or would it just not be feasible?
I think the military has been issuing earplugs for some years now. I further believe they are not nearly enough. My experience in the military...non-combat...was four years of pistol team competition with decent earmuffs. Even at that though the damage is cumulative.
