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.
Have you ever actually heard a 223 shot with a suppressor? I was just out shooting with mine 20 minutes ago. 40 grain bullets at 3800 fps. My dad was inside the house reading a book, 75 yards away, and didn't hear the rounds go off. Granted is it rather windy, and he doesn't have the best hearing. But still.....
To the OP: I believe everybody should have suppressors. It's a public health issue.
