Nope, I'm not confusing anything. A .223 flies at about mach 2 to mach 3. There will still be a lot of noise even with the suppressor and hearing protection will be needed if you aren't going to lose your hearing.
I'm trying save everyone's hearing. Go ahead and shoot without hearing protection I don't care. Ask your self why do ammo manufacturers manufacture sub-sonic ammo for suppressor use if there was no need for it.
So show us some documentation of testing in which a suppressed rifle got louder using any kind of ammo, measured from any perspective
