We are working on a path where we can comfortably provide that data....@Unknown Suppressors if you showed the decibel readings of your "baseline test can" (ultra 7) it might quiet some of those who seem to think your db numbers are way off.
Dm sentI am really sorry about your experience with your OG, it sure is a disappointment to hear it went so poorly. Please reach out to me in DMs and I'll figure out how to get you a full refund.
You're talking my language here. Musician and former audio engineer.If those numbers are correct, that's a huge difference at 6 dB due to log units of decibels.
OG is 2x as loud in terms of measured sound pressure. As I posted above, it would need to be +10 dB to be "perceived" to be twice as loud since our ears and brain are not as good as a meter for detecting pressure change.
For humans to notice a change in sound, many consider +3 dB to be the smallest detectable. But, some with optimal hearing may detect +1 dB.
One thing to note is that Unknown listed A-weighting for the Reaper and no mention of weighting for the OG. A-weighting is used to represent the frequency response of the human ear, which is OK, but I'd rather see no weighting or at least consistency in the reporting. Unknown may benefit by cleaning things up a bit. And we still need to know what equipment was used - maybe I need to check the podcast.
In terms of tone, that's a rabbit hole. And actually "tone" is not technically the way that I would describe the claim. A tone is a single frequency, and it is unlikely that the spectra (data in freq domain) is centered around a single frequency. In prod dev, we'd call it "tonal quality" or "sound quality". Yeah, it's nitpicking but it's these sorts of things that make people raise eyebrows and question the technical ability of those reporting the results on the website.
I worked as a noise engineer for a bit, but I am not an expert in sound quality - it's a slippery slope, as it involves psychoacoustics. I think I posted about it before, but it is a highly specialized field in acoustics. There are special (expensive!) sound quality packages available to post-process noise data based on how the brain interprets what it gets from the ears.
Anyway, I was just a Test Guy in acoustics, but was involved with some sound quality studies. The studies were led by a licensed Chief w/advanced degree in Acoustics as the analyst. Just when we thought we'd get widespread agreement from the test subjects, it fell apart. It fell apart because of a robust test plan. If we just made some measurements under a few conditions, we might have made bad conclusions.
All that to say, it is extremely common to hear people make all sorts of claims about noises, tones, etc. that don't make sense to a noise engineer. People hear something then make some bold claim not realizing individual differences or limitations.
For example, early on there were claims that the tones from the OG were less disruptive to big game. That may be true, however that assumes that the frequency response of deer, elk, pronghorn, etc. are the same as the human ear. We know that's not the case, they have different frequency response and a noise engineer would be cautious to assume that what he/she heard was the same as what an animal perceived. I haven't seen or heard that claim in awhile, so maybe it's not being used as a selling point now. And to prove it, would require a robust test plan which would be daunting and probably worthy of PhD dissertation!

To be clear, I think it’s a (very) small minority who thinks they have been “lied to” so I wouldn’t stress that too much! More so just a bit bummed out with the timing of it but understandable. Appreciate you chiming in @Unknown Suppressors, good stuff.4. If you feel like you were an early adopter and lied to about what your OG is exactly please reach out to me. (rokslide DMs are the most reliable way) and I will make sure that we do something to soften the blow. Sincerist apoligies if you feel this way.
Sorry it took me so long…To be clear, I think it’s a (very) small minority who thinks they have been “lied to” so I wouldn’t stress that too much! More so just bit bummed out with the timing of it but understandable. Appreciate you chiming in @Unknown Suppressors, good stuff.
Holy smokes, this makes 100% sense and is obvious to me now that you point it out… never even crossed my mind… this messes up all my averages….
They are using Larson Davis Spartan M821. It is the same that I just got.
Oh we have learned the limitations… and we are planning on getting a better one but yeah…. They are expensiveGood deal - thanks formi. The gunfire variant seems handy, but I've never used it.
So 48k sample rate and A, C, Z weightings? FYI - you may miss the true peak with the sample rate and rise time. Not saying that you should sell your truck and buy an expensive analyzer, but just know the limitations.
Can you run A-weighting and Z-weighting at the same time?
