When I was an army medic attending the armored cannon range in the mid 60s, I was constantly tearing apart bandages to supply tank crews that begged me for cotton for their ears.Military did no see need for ear protection, NCOs yelling was louder then small arm noise.
I am almost deaf thanks to wisdom of military.
Beside GIs we’re expendable.
My hearing survived years of standing in front of a guitar amp (luckily not playing hard rock), but it was pharmaceuticals that finally gave me tinnitus (like your head is full of mosquitos).
Needing ear plugs at a concert is bad enough, but the world is really out of control when you can’t play pool without them!
