According to my audiologist at the VA, without hearing aids I'm legally deaf. Appearently, my ears don't feel pain from loud noises and since the plugs the Army had in the early '70s would "pop out" of my ears and things like claymores, M-16s and grenades didn't bother me (as far as my hearing goes - lol), I just didn't wear them.
I've got Peltior muffs that are about 10 years old now that work great for me. I can wear my hearing aids with the muffs and carry on conversations with my shooting buddies at an active indoor range! They only "clip" at the point of fire and the response back to amplification is almost unnoticable, to me.
They have an adjustable volume switch that allows me to max volume on the range and lower it if I go into the store to get extra ammo or targets. I actually hear better with hearing aids and my muffs than I do with hearing aids alone.
I've been sold on Peltior for a long time!
