OSS Suppressors: Helix-QD - Hearing Safe Part 2

[Music] all right everybody welcome back this is randy from OSS I've got Tim here from military arms Channel he's gonna be joining us in this video now some of you online have been asking we read some comments online and some people have been stating that it's actually important to have those numbers off to the left to be really quiet and I guess the reason or the rationale behind this is that you want to be quiet to the enemy or the game that you're shooting and so if our numbers are loud at the meter to the left that's an indication that our suppressor is loud downrange right what have you heard about it surprisingly this is a question that comes up quite a bit in my suppressor videos I keep getting asked over and over again can you please do this test can you please do this test so I'm really excited to do this test because it's finally going to answer that question yeah how loud is a gunshot or suppressed gunshot at distance yeah so about about that a few things we're gonna do we're out here in this in this BLM land we've got this controlled environment we can see for miles around we've got a steel barricade me and Tim are gonna be standing behind we're gonna get his meter set up on it so that he could be out there and we can reset it we've got some radios so that we'll have constant communication between the shooter and we're gonna drive this barricade out there and then we're gonna begin backing up what we're trying to capture is the sound of that bullet passing by and the sound of any support of the file and the sound of the report of the fire yeah now I'm not in a spot where the backsplash or the or the berm or in this case the mountainside is going to be closed because I didn't want that to distract from anything else the meter might be picking up so we're just gonna see how loud the gun is how loud that report is downrange at various distances and we're gonna try it with our suppressors we're going to throw some competitor suppressors then we're gonna try it with no suppressor at all and just see what those numbers are this should be really interesting all right let's go do it guys what we're about to do may seem dangerous but in actuality what we have here is a our 400 armored plate we've taken some test shots with a 5 5 6 rifle and this is going to act as a barricade for us we're gonna stand behind this and just outside of this we're gonna have a brew looook air meter set up the point of this is to demonstrate how loud a 5 six rifle is at 25 yards and at 200 yards suppressed an unsuppressed and that's using the OSS suppressor and the competitive suppressor so the shooter will be 25 yards to our right and they'll be shooting at a target that's 25 yards to our right and again we've confirms a row and we've tested the fact that this steel plate will protect us from a stray around don't do this at home what we're gonna do now is we have a shooter that's 25 yards behind this armored wall and 25 yards to my left we have our meter set up and we do not have a suppressor currently on the rifle so this is going to be an unsuppressed shot we're gonna fire three rounds to get an idea of just how loud the report of the firearm is and how loud the bullet passing by is because it will create a sonic boom Randy here is gonna tell him when to fire so he'll say fire will meet her it and then we'll clear it reset the meter and he'll tell the fire we'll do that for three rounds all right we're ready to go it's gonna get the meter all set up here all right you can go ahead and okay go ahead and fire all right so we have 138 point 2 decibels on the meter again that was without a suppressor go ahead and reset the test go ahead and take the next shot and again we have one hundred thirty six point six decibels for the second shot wait till it shows a new ambient noise go ahead one thirty six point nine so we're looking at about a hundred thirty six decibels without a suppressor from 25 yards away so we have the helix QD attached and we're going to fire three rounds and see how loud it is at 25 yards all right so we have a reading of 133 point two okay 132 0.8 and one eighty one thirty two point six variation no well pretty consistently consistent now we have the competitive product attached to the ar-15 when firing five by six once again and one thirty three point one okay one thirty two point six okay one thirty three point seven so now we've reset the test we've moved the shooter back to 200 yards still 25 yards to my left but they're back at 200 yards we're gonna fire one round unsuppressed just to get an idea and then we're gonna fire three rounds from the competitive product and then also the OSS will actually shoot the OSS first all right are we ready guys okay alright so one thirty one so that's pretty cool so we heard the crack of the bullet yeah right crack he had just right out there I'm just like with a solid delay before we heard the boom the echo of the un-- suppression so hopefully you guys heard that we heard boom following it so we had a peak pressure of 131 decibels so now we've mounted up the helix QD in five five six two hundred yards same ammunition same rifle and now we're gonna fire okay so one hundred and thirty point nine decibels 130 points six decibels so now we're really hearing just the crack of the bullet right we still hear a little bit of a report but it's the crack of the bullet yes interesting so this is picking up the peak sound at 136 130 point six so there's no way because we could hear a solid delay before we hear that suppressed boom 200 yards you could actually still hear it slightly but it's there it's it's noticeable so so the crack of the round it's coming up coming through here and the crack of the round is 130 point 6 and that's actually very similar to what it was even at 25 yards right so 128 flat yeah I don't know if you guys could pick it out but it's a distinct pop sound we're hearing first now we have the competitive product with baffles mounted to the same rifle 200 yards 25 yards left of us alright go ahead and fire one 31.6 yeah it's not as loud as it was unsuppressed right here but I'm still hearing it right so you hear the crack the bullet crack is definitely peaking oh yeah that's the peak no no you're not about the crack right out there is the loudest thing without a shadow of a doubt 129 0.9 so we're hovering right around that 130 it's actually pretty dang consistent 130 1.8 all right so really there's no difference yeah I'm actually curious at maybe we'll move it back to 400 I'm actually curious to see how far we have to move the firearm back before we can so that we actually don't hear the report of the of the rifle itself so that I guess in theory all we would be hearing is the crystal crack now the shooter has moved to the 400 yard line still 25 yards off to my left and we're going to fire one round unsuppressed and then we're going to fire the competitive product with the baffles next one thirty one point seven so we're it's definitely the supersonic boom of the bullet doing the peak yeah big low much longer delay we have we almost heard flight paps heard the bullet the skipper racking right yep heard the pop first and then the poof in the background yeah now they've mounted the competitive can using baffles and they're going to fire three rounds from four hundred yards but it's not discernible here that it's a very faint 130 point nine so most 131 decibels yeah but it's just it almost sounds like a book falling to the floor a long ways away it's on a run really padded carpet right let me it's almost where you can't pick it out that snap is definitely what we hear now one twenty nine point nine yeah so keep a nine or also it's pretty flat out here I would assume if there were a lot more maybe trees or cliffs reflective surfaces maybe even at four hundred we might still be able to hear the suppress rifle but it's just a but it's very faint a very faint thud no question the round passing in front of us it's consistently right at a hundred decibels at every range one twenty eight point eight yeah the ricochet was louder than the back over there yeah all right so one twenty eight point eight so what we've learned is that a bullock a bullet a five by six bullet breaking the sound barrier peaks at 138 decibels at least at this distance from whatever distance the round is passing by I guess the shooter is at 400 yards we've mounted up the helix by five six twenty-five yards to our left and go ahead and fire one round one twenty eight point eight one 28.7 and again a thud yeah off in the distance one 30.9 so it's the bullet breaking the sound barrier yeah I would say there's a difference I could hear a slight difference between the kinds of thud how loud they are they sound really similar but they are bugs you still hear it even at 400 yards right and none of them are louder than the bullet one no so if you're trying to conceal your position you're you're you're giving away the fact that you're shooting at something yeah because the bullet cracking going by is louder by far than the gunshot yeah I mean it would be interesting to try this with subs where I guess in theory we wouldn't hear the sonic crack blowing going by but then the ambient noise out here being about 80 DB I don't know how well it pick up even that faint thud right in the background it'd be very hard I would assume dude just try to figure that out but it would be interesting to at least experience it yeah yeah good test all right so we just got back doing some of that downrange testing with Tim's meter and it was actually quite interesting and I guess my question to everybody out there in the industry at this point is is measuring sound at the old standard of 1 meter to the left relevant or if so how is it relevant maybe some of you can comment below because the results were interesting even at the 25 yard mark the 200 mark and the 400 yard mark there were all the same so that cracks seem to be the loudest thing that we heard as the suppressors or the shooter I guess was further out we would hear that distant that I guess the report of the rifle that would be more faint at farther distances we could hear it at 400 but it was still there on both camps and consistently regardless of the distance we're right around having 30 decibels that was all the bullet crack that's breaking the sound barrier it seemed like the only time that the unsuppressed report was was any different at all is when we were really close right 25 yards after that suppressed unsuppressed as far as the meter was could tell the peak sound consistently every time was the sonic crash of the round about that peak sound something we should probably mention that we didn't really get a chance to mention earlier OSHA's standard for 140 DB so OSHA has a lot of standards as you know and as I know you get a lot of flack sometimes on the internet for wearing ear Pro and you're shooting suppressed or not wearing ear Pro technically speaking OSHA calls for 140 DB as the threshold if we're talking about what do they call impact noise impact much impact noises there is there is an exposure factor here that a lot of people are missing that we should probably mention the impact noise we're really talking about a one-time occurrence technically speaking if you were a fire your rat your rifle with a suppressor on it and let's say it was even 132 DB technically you're really only able to do that once a day once a day basically so if you're gonna be doing any type of firing in any regular environment where you're doing round after round or especially with belt feds if you're running something or something full-auto you should probably be wearing hearing protection another thing to note is out here it's pretty flat we're out here in this BLM area and there's quite a bit of fields I mean we could see for miles out here and the sound carries how do we shut up here is relatively cool yeah I'm we got here about 23 degrees yeah and then I don't know what is it 55 degrees about 55 now 55 degrees right now so things warmed up I'm certain that it's somehow affected the numbers we had done this on a different day at different time of the year or even in a different location our results probably would have been different right it goes back to what we talked about in the opening of the video all the different variables that dictate what you're gonna get in terms of meter readings so anyway Tim I just want to thank you again so much thank you for being here it's been a pleasure this has been a real real treat for us to actually do this downrange testing with you I'll tell you what man I had a great time and I really learned a lot in this session so much so that I actually created a video myself of what we were doing I heard this afternoon this was really really educational and something that my fans and followers have been asking for for quite some time so thank you for having me out yeah yeah we thought it was worth doing absolutely so everyone again thank you for watching this one keep leaving those comments down below your comments have been really helpful we enjoy reading them and we actually enjoy answering some of your questions and maybe even doing follow-up videos based on those comments so keep those comments coming thanks for watching [Music]
