thanks for the replies and sory for using the wrong spelling/ term. I'm just shocked that out of all the post no one just said quit being a wuss. I will be wearing plugs under my elctronic muffs from now on.
The VAST majority of the electronic muffs out there are in the 17-22 db range. So a 165db report is reduced to 148 to 143 db. Those sound levels are high enough to leave you with permanent hearing damage. The only e-muffs that are good enough alone are the Pro-Ears Gold. Every 3db DOUBLES the sound pressure on your ears. Every 10db is 10X the pressure and 10x the damage resulting in 10x the amount of permanent hearing damage. A good set of muffs that are rated for 33 db are 10 times better than ones at 22 or 23 db rating.
The Pro-Ears literally make the sound of the reports go away. It's so good it's scary because you can still hear everything else. But so is the price (scary). I've got 2 sets of them because I HAVE to keep what's left of my hearing intact. The price is high but still a small fraction of the cost of hearing aids and is nothing compared to the continual embarrassment of having to ask people to speak up and repeat what they said.
Sorry to harp on it, but having lost hearing ability I can't sit back and watch others repeat my mistakes

Do double up, but I would suggest that you get a set of non-electronic muffs that are rated at 33 to 36 db and use GOOD plugs. I just bought an extra spare set of muffs from Harbor Freight today for 12.99 that are rated 36/33.
