Unknown suppressors OG testing

Interesting, I thought the sTi was supposed to be pretty quiet. Maybe I missed it but where is the reaper stacking up?
This is where I got confused. The sti was under a db to the U7 at the silencer summit. I missed the results posted today where it was more than 2 db louder.

On any given day with different conditions the dBA will vary. There is a +/-; TBAC says +/-2 dB. I’ve seen almost 4 dB variation- it’s just how sound and the testing works.

As for the DD STi… yeah I don’t know. You can go back over a year ago and see the I and others were reposting that they were “cracky”, and have a pretty definite “ting” to them- more obvious in the cold. IIRC there were 6-7 people with the same take away from them.
They’re just not a good can. On top of them not sounding all the great, S2H has 7 or 8 of them, and 4 make almost every rifle they are mounted on a 2-4 MOA gun- again I have written about that since last spring.

The flip side is the LTi is a good can and does sound (and meter) well.
 
Where did I say it was bullshit??? (Hint:...never) I said It was a gimmick and it is because it's not something that improves performance, it's just another mouse trap. If you're going to tag me in stuff, at least tell the truth.

I could cut 3" off any silencer and it's going to be louder. Taking length and volume off a silencer and showing how its louder isn't really the "gotcha" moment I think you were looking for.
I see a 7 dba increase when the OTB gimmick is removed. Why do you say it doesn't improve performance? What am I missing?

I remember reading that, now that you mention it. Did you guys ever figure out what was up with the cans that caused accuracy issues? Runout or hub mounts not being concentric?

Haven’t been able to see a reason why, have swapped a bunch of end caps, hub mounts, etc. around. The worst can- one that has made nearly every rifle a 4-5 MOA gun, shoots excellently on the Browning X-Bolt II 7PRC. I would need to be more rigorous with it, but it does seem that now that have a lot more (relative) rounds/carbon on them- they aren’t as bad as they were for the first couple thousand rounds.

Dude. Of course there is a sound increase when you remove a section of the silencer.

That would happen with 100% of silencers, look at the difference between a TBAC ultra 7 and an ultra 5, the exact same thing but one is shorter with less volume.

The gimmick is that the OTB thing really dosent buy you anything meaningful unless an inch is worth something heavier and louder.

I’ll concede though that it’s a gimmick to me. The way my nomad ti xc is setup, my gun is less than 1.25” longer than it would be with an OG, I’m also lighter and significantly quieter with the ti xc than I would be with the OG.

Again, a 7db reduction with the OTB section added.
 
I did in fact answer it. It is averaged correctly- as it should be. You can take the numbers given and add them up and see if it is done correctly, or just and averaged normally.

What you posted, using the online decibel calculator, was the log average. Or for noise and sound geeks, the dB average. It was appropriate.

As opposed to the arithmetic mean, which would be the wrong way to average log units. This is a common mistake - noise/sound guys see it a lot from people who don't use log units.

Just note that when you compare one noise reading to another reading, it's appropriate to use the arithmetic difference. Just subtract like regular people.

While I'm at it - when you post weighted values, it's normally shown as dB(A) for example.

Noise/sound guys get suspicious if the units are not used correctly.
 
I'm just asking a question. You were the one comparing two different cans, including one that doesn't even exist yet.
What you’re doing is trying to play the “gotcha” game. You people are so weird, like anybody who has differing opinions and feelings about silencers really brings out the crazy folks.

Ok, this seems tough for you to understand. Try to follow along.

He got a sound reading from a silencer….ok. Then they added volume to the silencer and it got quieter. This would happen on any silencer, add volume, it will get quieter, take volume away, it gets louder.

I’ll say it again though, the gimmick is that that over the barrel design, isn’t quieter than a silencer of equal size, it’s not lighter than a can of equal size and it IS louder.

So, if you are willing to use a heavier, louder silencer so that you save an inch or so in overall rifle length, then the OG is a great choice.

Differing opinions based on evidence are excellent and often lead to better outcomes, but relying on subjective feelings or unproven beliefs as evidence is not adequate.

I don’t care about the rest of what you wrote, but you keep saying “an inch” difference in OAL- it’s over 2 inches or 25% savings in length for the same suppression.

For the vast majority of people that respond online and in person- added OAL is a really big deal. Suppression and added OAL nearly always #1 and #2- though different people will swap which is more important.

What do you mean “the same suppression” the example I’m using is my dead air nomad ti, in its factory form it adds 6.25” to the length of the rifle. The OG adds 5” to the length of the rifle. The nomad ti xc is quieter and lighter. And only 1.25” longer. For some people that might be worth it and that’s fine. I’d personally take a reaper over an OG.
