Does anyone have any media of the FTN.4 or decibel readings? I’m curious about the suppression levels of the full size suppressors.
OpenPew@forum.guncadindex.com You know where this guy might find this sort of data? I thought plaboi and his testers did some good number crunching, but I’m not sure where we’d find the data.
I’ve never heard of legit decibel readings for the ftn cans (or any 3dp can I know of lol). The problem is getting ahold of a decibel meter that can measure quick enough pressure impulses, and they are thousands of dollars. Phone microphones just don’t respond fast enough to the microseconds long pressure waves of a gun shot. Would be amazing to develop some sort of diy way to just ballpark it though - maybe some bursting pressure caps of increasing toughness… can’t be that hard considering the big magnitude difference in pressure between even eg 130 and 136 db
I guess I’m mistaken then, damn.
Maybe theres something out there that i dont know of, but i thought i remember a long winded post about how you cant get accurate db numbers without professional equipment
Exactly, and I thought the FTN testing was so super insanely fast and impressive that it drew the attention of someone who had that sort of equipment.
unfortunately i do not think that the results of the professional testing that was conducted was ever published. I had a line on a guy who claimed that he had tested the ftn series and several of my designs with pro equipment but he stopped responding. i have theories as to why but it remains a mystery.
Pretty sure that’s true, since some of them can’t actually capture how loud a gunshot is. For example, I saw a video of a guy shooting an unsuppressed 45, which came out to 113.8, then when suppressed with a commercial can, 87.4. But I was kind of surprised and disappointed to never see any numbers, which would be more useful than audio. Even without professional equipment, you can still get a general idea of the reduction levels I would think.
I recall seeing a video of a guy with a decibel meter on their expensive-ass phone and attempted to get readings out of an unsuppressed .45acp and then again with an FTN4 installed. It went from ~149 decibels to ~125 or something very close to that.
In the end, the FTN4 brought it down into a range that was hearing safe for a few shots. For comparison, the same firearm with a popular standard-baffle commercial suppressor wasn’t able to do much better than the FTN.
Hope that helps!
unless the transducer was a 300+ dollar type, its not going to have quick enough impulse time. what its probably measuring is the reflections of sound from the environment afterwards which really isnt accurate to the actual sound suppression of the device.
