I can't remember if it was at psab or what but I was in a smaller detail (20) wedged between two Army company's (I think that's the right name, like ~150 or people?) in the same chalk. The group rotating back in were way fucking louder then the other and I pointed that out to someone with me who also noticed the same thing. At the time our guess was the quieter group were national guard going in for the first time while the others were active duty/permanent party and dealing with the funk differently.

Now I am starting to wonder if the one group's hearing was just collectively fucked?

Agreed. It's a raw pitch, with no articulation. For me it's a very high pitch, kind of a digital hum like when you turn a computer monitor on in otherwise complete silence, just louder.

Not everyone will experience the same pitch either. It's caused by the micro hairs in your inner ear dieing, which for some reason causes the pitch they were responsible for detecting to be stuck permanently on.

Closest thing to silencing tinnitus is distracting yourself from it with other, louder sound - I tend to have music or something on as often as possible, but that constant loudness is slowly killing more micro hairs and expanding the range of the tinnitus over time.

Old man me is gonna be deaf as fuck. 🤘
