Thread: Gunworks modular Stacker suppressor review

Those meters use a sampling time so long that the shot is "averaged out" and likely simply missed because the response rate of the meter simply can't keep up with the the rate of pressure rise (and fall) which is the actual noise. This also likely explains why the brake results are sometimes showing quieter than the non-braked results. Suppressors work by slowing down the escape of gas and a brake allows faster gas escape so the duration of sound is shorter with the brake on meaning a lower reading on the meter as more of the shot won't be captured.
Kit that can measure gunshots impulse is seriously expensive.

I would give your subjective impression of noise levels more credit than the numbers provided. For example, what's your impression is the bolt cycling louder than the shots with more than three baffles? (I'm being facetious to prove a point; of course it's not).

I wouldn't bother measuring an unsuppressed shot, suffice to say I bet it will be considerably louder.
