I like this chart too, so I stole it from you.Paladin wrote: ↑Mon Nov 28, 2022 4:39 pm
Anything above 85 dBA can damage the small hair cells in your ears and affect your hearing health, either over time or—if it's loud enough—immediately.
I still wear double ear pro even with a silencer. That gets the noise comfortably under 85 dB.
I also use earpro with a suppressor, particularly now since I’ve already gone deaf in one ear. That said, I have shot suppressed rifles with no earpro in an outdoors environment like out in a field, where there were no walls around to "contain" the sound and make it reverberate, and as along as I or my observer were behind the gun…whether on the gun, or standing a few feet behind…it was quite comfortable without earpro. And that was with supersonics. With suppressed subsonics, it was magical.
FWIW, I recently bought a set of those Axil in-ear plugs with microphones and active sound attenuation, and they work pretty well. I used them for the first time at ETTS just a week ago, shooting both suppressed and not suppressed, and they were great. The real test was shooting my SCAR 17 with a muzzle brake and no suppressor. My son hated it, but I was good to go.
