Even with a good suppressor and this, i cannot see it being hearing safe. It’s a semi auto 556. There is only so much you can do. Quieter or more pleasant sure, but not hearing safe. So when a claim is made that a 556 semi auto is hearing safe, to me it discredits the speaker, until it can be proven. |

A few things that people don't always understand about hearing damage... Just because you might not have ringing or persistent ringing in your ears after an exposure does not mean that it's okay and no damage occurred. The 140 decibel limit that people frequently refer to is for a single exposure. For ongoing noise or multiple exposures protection is required at 85. If I am saying this correctly, it's not a linear scale it's an exponential or logarithmic scale like earthquakes. The action noise and or supersonic crack of the projectile either one alone and especially together can cause hearing damage in and of themselves. All that being the case suppressors still have additional value far beyond hearing protection such as recoil reduction flash reduction ground signature reduction etc etc. That's why for me personally I look at an overall performance versus size and weight picture not just a decibel reduction. I generally want a suppressor that's going to be as small and light and compact as reasonable while still maintaining some decent sound reduction as opposed to chasing the biggest possible decibel reduction because you're not going to be able to make it hearing safe with the centerfire rifle anyways. So if I get some recoil reduction ground signature reduction flash reduction vision protection accuracy improvement etc for a relatively compact and lightweight suppressor then I'm good with that. I also prefer either direct threat on cans which are less expensive less weight shorter or cans that clamp onto a standard muzzle device such as an A2 or vortex. I have five suppressors currently. I really want to get a reflex suppressor. |

As TSH77796 said, a single sub 140 db impulse is, by OSHA definition, hearing safe. But multiple exposures to sounds that loud in a "short" period of time are not. So when they say "hearing safe" likely what they mean is the measured sound impulse is sub 140 db, which is technically true. But you are also correct that continuous sub 140 db impulses CAN damage your hearing, and very few people are going to be shooting a single round in a range session. You are 100% correct, hearing protection even when "hearing safe" is the way to go. Sven Manticore Arms |
