do you think damage occurs to your hearing and or to your brain
I've been muttering "Pardon Me What Did You Say" ever since my Marine Days. The VA deposits in my bank account a monthly disability payment. I'm also inadvertently really good at reading lips.
I think that depends on how they define "no advantage." If your muffs seal perfectly, then maybe not, but a lot of people's don't, for a variety of reasons: facial hair, oversize eye protection, etc. So the second line of defense is a pair of good-fitting, high-rated plugs.Can't remember where I found it but there was a study done on hearing protection and they found no advantage of doubling up with ear plugs and muffs.

In order for there to be damage to the brain, the head has to be hit and and the brain has to be stopped fast enough that the brain will hit the skull. It doesn't take a lot to do that, but the concussive force from a pistol or rifle would really have to be high to cause this to happen.
You may be thinking that the NRR isn't additive and that you only have a net gain of 5dB from doubling up instead of doubling the NRR when you double up. It is also important to understand that each 5 (or 3) dB reduction represents a halving of the pressure since we're dealing with logarithms. So, that extra from double protection is still cutting the pressure by half even if the gross number isn't doubled.
Wear plugs under muffs. You're hearing will benefit.
"An animal study demonstrated mild brain injury in pigs and rats from blast overpressure from artillery (155mm howitzer), anti-tank weapons (Carl Gustaf 84mm recoilless rifle “bazooka”), and high-caliber military rifles (M82A1 Barrett .50 caliber sniper rifle). Small hemorrhages in the brain, increasing with blast intensity, were seen in 21 percent of pigs exposed to M82A1 .50 caliber rifle fire and 7 percent of those exposed to Carl Gustaf fire, even after as few as three shots from the weapons."

I recently had to have a Brain Scan based on the picture I posted. It was interesting to be told by the neuro surgeon, that read the scan, about a few MTBI from Non-Direct Exposure to Blasts. We also completely revamped our indoor range due to the amount of members being tested and showing lead exposure at dangerous levels. One of the areas was UNDER tables and chairs where cleaning was not normally done.
Ouch. I’ve walked into ones left mid lane, at my club and when they hit the stopper in front of the position it bangs, but that’s I first someone getting beaned. 6 staples.Don't get hit in the head by a return target carrier.
