That’s why all three (plugs, over the ears, and a suppressor) should be used in conjunction for best results.
General industry standards that I’m used to are as follows:
-sustained noise over 84dB should use plugs/muffs
-sustained noise over 104dB should use both plugs and muffs
-peak noise over 140dB should use both plugs and muffs, regardless of average sustained noise dB. If sustained noise is over 84 then start using additional mitigation measures such as sound dampeners, barriers, distance from noise generating object, etc.
That being said, if a suppressor brings peak noise down to ~135dB you should STILL be using double ear protection. But it’s way better than bringing it down from 170dB.
I would note that 30dB muffs over 30dB plugs does not provide anything even remotely close to 60dB reduction. It’s more like 33dB, because both muffs and plugs block only noise propagated through the auditory canal. They do not block noise conducted to the cochlea by bone.
At noise levels above ~140dB, no amount of PPE is capable of reducing noise to “safe” levels.
Yeah, that’s why PPE is always the last line of defense after other mitigating measures. In my industry though it’s often the best you can get due to the way the work goes so we have a bunch of old people with hearing loss.
Shooting guns is LOUD. For a recreational hobby it’s good to remove as many barriers to hearing loss as possible, so the US’s stigma against cans should change.
It’s mostly movies representing suppressors as assassin toolkit “silencers” coupled with a lack of education and the ridiculous cost and acquisition hassle for a piece of PPE.
USA has guns, like it or not. We should be encouraging education and the safest use possible every chance we can.
