For my purposes, I will sometimes use a cheaper dB meter to sort of "confirm" what I am hearing. I don't put it up against any stated numbers but for side by side comparisons it can offer at least some insight.
i.e. metering 120 on can A vs 125 on Can B, when can A reads 120.5, 119.9, 119.7, 120.1, 118.9 and can B does 125.5, 124.9, 124.7, 125.0, 124.9 within 5 minutes of each other. Are those numbers really 116 and 121 because the cheap device is off on calibration by a few dB? Maybe but as long as it's consistently off you can say "Yeah, can A did seem noticeably quiet, it wasn't just the tone or my imagination...."
In any case, it's why I don't ever talk about my el cheapo Chinese job... out side of a situation like this anyway. It opens way to many cans of worms and trying to go down all those rabbit holes can be exhausting and get some folks riled up. I'm not an expert not a scientific facility so I'm not going to try to pretend I'm something I'm not.
OP- thank you for the numbers, I've heard a few folks say they feel like the Oculus is a little quieter.
I like your rant... I've looked at a lot of metered numbers and watched videos with hideous sound compression and clipping and truly believe the best instrument to measure suppressors is that of you and your friends ears. Shooting not under a roof at a range and not in a pit but preferably up on some flat ground not next to other buildings or trees. I enjoy letting my friends shoot my suppressors while I stand and different distances inline and behind the ejection port. Sometimes I will even stand 30 or so yards downrange and about 15 to 20 yards away from where my trusted non drinking friends will shoot at a non frangible target.
The Occulus is pretty damn quiet but so is the Mask. "They" say that it has to be 3-5 dB more or less than the other can for us to hear any difference. The state of 22 suppressors seems to now be where if you are a few feet away all you can hear is the clack of a Ruger 22/45 Lite, a Walther PPQ M2 .22, a Ruger SR-22, Walther threaded barrel .22's before the PPQ.... etc, etc... I like S&B subsonic or Aquila. Gemtech subs are noisy and I don't like American Eagle anything... their 124 and 147 subs may be subsonic but the noise they make in my suppressed 9mm handguns and MP5 is unacceptable. S&B 158, IMI 158 and PPU 158's are all very quiet and to me are just a hair louder than the excellent but expensive and hard to find in Alaska HUSH. My hand-loads are the best at being quiet and functioning everything....
