Q&A answers from the first few comments: 1. Can you do fan and noise tests at the same time? A: No. All other lab testing stops for noise testing, except for standard bench tests in a distant lab room. HVAC is also turned off for testing. 2. Do you really do noise tests late at night? A: Yes. We always have done noise tests outside of traffic hours and our test facilities have always been located away from main roads, so getting 0 traffic is easy. We typically test at night or very early morning. 3. But why do you try to get 1-2dB lower? A: Because the point of the operation is to get the best reasonably possible. There's no point settling for worse test controls if it's as easy as wheeling a box around to get something better for our content and reviews. 4. Will you add more acoustic padding to this room? A: We thought about it, but the noise floor is so low here that our next most sensible move would be to save that expense to instead build our full room-scale anechoic chamber. That'll be in the future a bit.
Your dedication is incredible. > the point of the operation is to get the best reasonably possible I think you might consider "reasonably possible" quite more extreme than others, lol. A lot of people wouldn't bother doing overtime / working outside "normal" hours just for a slightly more accurate result. Here's hoping that you get no meaningful difference on the inside of the chamber regardless of when you do the testing!
I am surprised you're going to need a desktop PC for the data collection, just because most people in voiceover use a fanless device. I wouldn't expect a fanless MacBook Pro would work for you but the fanless Surface Pro or something like it might (and the fanless models tend towards the lower-end of the price range). I hope you do a review of the passively-cooled desktop PC - a lot of VO people who use the PC platform would want to see it.
It is incredibly satisfying seeing The Lab fill up with this awesome gear and how the team is able to drive precision and accuracy to insane levels. As most of the audience will never get to see this kind of equipment up close, it's really cool that we get to come along for the ride and see it in action.
As an acoustical engineer, I’m so happy to see this. Many companies use very similar booths but having a 3rd party tester is always a positive. I bet many of them would GLADLY participate in round-robin or Inter-laboratory trials with you.
@10:30 In case 137 people haven't already warned you, the fanless PC could still have coil whine. I know that's normally not an issue with motherboards, but considering the noise floor you're shooting for, and how sensitive the measuring mic is... It might at least be worth quantifying. 🤷♂️👍️
I'm absolutely loving the battle of the labs at the moment. GN gets power supply tester and fan tester. Aris gets fan exactly the same fan tester. And the respect to be like "no other UA-cam outlets, barring hardware busters" just great stuff in general.
@@jmacd8817 couldn't say anything about llt except that the only time I watch any of their content is when people are addressing the mistakes they made in a video.
Kind of wild to think about the history that chamber has, and all the products Apple must have tested in it. Always cool to see that kind of gear make it's way to less wealthy owners as time goes on, and help bring them up in the world. I've handled so much gear like that in my lifetime living here in the SF bay, at one point I had basic equipment from all the major players in my workspace, things like Herman Miller chairs and the old Galant desks and cabinets from Ikea. Have had some nicer stuff as well, just not PC tech related. I've got a bunch of the speaker tops that were on the last pink floyd tour for example, stuff that's almost as old as I am and heavily used but still going and sounds fantastic. Excited to see what new stuff comes out of this in the near future! Just wait, soon people will be begging you to test some of the audio gear apple makes to call them on some kind of bullshit xD
@@iosonolucaio Well yeah, and that's exactly why I'm looking forward to this build. Most passive builds I've seen on UA-cam are just done for novelty, this is going to be done for one of the narrow use cases where it actually makes sense.
It's nice to see another person that puts this much thought into things they do. People around me would always make fun of me or say I'm crazy or that it doesn't matter. Thanks for all you do man.
Make sure wherever it ends up it's at least 4 inches away from any wall for a proper airgap and avoid contact with any hard surface like that pole for instance. I build medical grades ones and that's the rule we follow. Love you all! Good luck! Edit: also can't wait for my cups and coasters to arrive!!!
From my point of view it pretty much makes sense that the quitest place in that room would be near the bathroom. In german we call the bathroom sometimes "stilles Örtchen" which translates literally to 'quiet place'. Kind of weird but fun I guess.
Good Tip could save in the future. I work in facilities and renovate/move these power poles alot. Terminate the main circuit off in the ceiling with a Commando socket. Ideally in the centre of the room. Turn the power pole into an extension lead with the command leaving enough flex. You can then move that bad boy without an electrician !
@@CptJistuce Defo depends on setup. If it's going to be fixed for numerous years then go hard wired. If it's a case that you have to move it a lot then commando is a good option.

It's great to see how you guys are really taking the time to set this up well so you'll get data that will be useful for comparisons far into the future. Plus I just like test equipment.
a nice idea i think it will be to create a booth around the chamber like a rectangle with 20-30 cm longer sides and a front door . open a few holes for your cables and have that booth covered outside and inside and top with those noice reduction /redirection panels / foam etc . also you can put some type of ruber carpet under the chamber to reduce any noice / vibrations from the floor travelling up from the wheals to the metal structure of that chamber . for more extreme status . you can make an extra booth covering the other two . but that is just crazy , or not ? anyway also plz forgive me for any grammar mistakes , english is not my primary languange .
Y'all should bolt the passive PC onto a desk in that hole between the wall and the chamber. It'd be right by it for easy data transfer and itd make for a fun build.
Vibration decoupling could potentially play a part in the chambers noise floor. Set the chambers on some rubber feet rated for that weight, and make sure it deforms elastically a few mm's, and the resonant frequency should be low enough for A-filtered measurements.
Had a few corsair fans fail me, and looking to re-fan the entire PC in my next build. Pretty excited to see which fans are junk and which are good, as they pretty much all cost ~$20 canadian, with few exceptions.
Glad to see two best actual tech UA-camrs are fully determined about higher tech stuffs. Ltt is gonna be the fancy one with tons of spaces and facilities. When GN gonna make mango people dream true.
Build a small room around it. Line the inside with plastic, fill the walls with sand. Then you can put some form of acoustic foam inside if you believe you will even need it at that point. The sand should do most if not all the work. But I think it's best to give you guys an honest chance at creating an environment for round-clock usage. Might have to make a custom door of sorts, but it will be worth it and I think probably a relatively inexpensive solution. Basically a vocal booth on steroids. An extra ~500$ isn't much to make an 8x8 or what have you.
Just a suggestion to assist with placement. Rather than finding the quietest part of the room building a small room/enclosure.

How much performance would the noise collection computer need? A purely passively cooled arm based soc board may be easier to keep cool, and less power being thrown around to risk coil whine.
At (this low of a) noise floor, could "electronic" noise like coil whine from PC components, or just electronic interference, become an issue? Even aside from GPUs, I can every now and then hear things like transformer hiss from PSUs/UPSs. And I'd assume that some MBs are buzzier than others too.
Awesome. ❤️ Off topic question : when can we expect the new Intel laptop reviews if you plan to do one ? Really would be cool to hear your opinion on Intel's new features and gpus. ❤️
Why not use the chamber metal itself as a heatsink for the testing PC, and find a brushless motor than can handle very low voltage input to run a massive fan at as low of power as possible?
It's dope that the mic for noise testing is so sensitive but it seems like a bit of a bummer you've still gotta shut so much off even with the sound chamber.
Curious about the egg carton pattern on the inside. Is it a bit worn down from who ever last owned it, and if so, does that affect the results vs having a new pattern panel thing put in it?
Do you think you would see any improvement from adding some sound panels to the walls. I wonder if and how much insulation that dropped ceiling has as well. Might not lower your noise floor but help keep it low.
would adding some sound panels /bas traps into the room help to trap just a little bit more sound? or would that just give enought measureble gain in an already quiet room?
How would you point the microphone at what ever your testing in the noise measurement box? The box looks kind of absorbent like an mini anechoic chamber so "98%*" of the noise emitted will never hit the microphone? is there something like an Integrating sphere for sound? *random guess
I can’t remember if you guys mentioned previously, but are you guys renting the new spot or did you guys buy it? Looking forward to seeing what you guys do with all the space
Isn’t the point of having a box that reduces noise that you can put it more places? I’m not sure why 1-2 Decibels difference of external noise would substantially affect the noise measured internally within the chamber. Genuinely curious because I’m sure you guys have solid reasoning but I just can’t see it.
they talked about it a while back, i think on the main channel. even the copper wires going through the side ports into the chamber can carry vibration through the metal. so they have to be super careful to eliminate as much as they can from all areas. starting with the quietest part of the room seems to me to be the best logical point.
If we can make it better, we should. This made it better. We want the starting point for testing to be the best possible. The box isn't good to the point it eliminates all noise (none are), so we have to do the best we can.
@@gnextras Reading the FAQ I had no idea you guys already took so much effort in your fan testing. Getting up early, turning off all noise producing appliances to lower your noise floor. Insane work you guys, that's why you're the most trusted team in tech!
One thought - with the fan tester and the sound chamber in the same room, you probably won't be able to overlap testing (I assume the fan tester is relatively loud) Or are they just too big to move further into the building through normal office doors?
Sorry if this already asked but why hide the manufacturer name/model for the fan tester? I mean I know what this exact model is but I can't see a reason why you guys would want to hide it. Just curious, thanks!
Whenever I see Steve in a full body shot he looks like he's a short guy, can't tell if it's just an optical illusion or if Steve actually is sub 5'10".
Have you considered for your testing methodology that some more "normal" points of data might be useful? It's fantastic to know how scientifically quiet a fan is, but it would also be great to get "sure this is XX dba quieter, but that's completely un noticeable in most people's environments".
Questions like this really dont make any sense. Please understand, When someone without any "scientific" testing tells you a Fan is quiet, Its incredibly difficult to understand if that means quiet for you; In you're environment . If that dude lives next to a welding shop in NYC he might consider a fan to be quiet. ( Im exaggerating on purpose here) BUT if you take those fans and put them inside your suburban house without running air conditioning, they COULD be loud as fuck. If you take the information and actually apply it, You will have a real understanding of how loud that fan ACTUALLY is. Sometimes you have to think for yourself, Instead of wait for your exact answer
@@youtube.really.stole.my.handle That kindof illustrates my point. NO ONE has an anechoic chamber they live inside of. I'm not saying don't tell us the dB level, I'm saying throw in some points of reference specifically for the point of relating to your personal situation. Not may people know the noise floor of their dwelling, but they certainly know if they are urban, suburban, or have central HVAC. Making one fan out to be better than another because it's 2dB quieter doesn't matter if that is 10dB below a "normal" noise floor, and therefore there would be no point in spending $20 extra for it. That's an important consideration in a review that is lost if you just focus on "this one is quieter".

they talked about it a while back, i think on the main channel. even the copper wires going through the side ports into the chamber can carry vibration through the metal. so they have to be super careful to eliminate as much as they can from all areas. starting with the quietest part of the room seems to me to be the best logical point.
If we can make it better, we should. This made it better. We want the starting point for testing to be the best possible. The box isn't good to the point it eliminates all noise (none are), so we have to do the best we can.
@@gnextras Reading the FAQ I had no idea you guys already took so much effort in your fan testing. Getting up early, turning off all noise producing appliances to lower your noise floor. Insane work you guys, that's why you're the most trusted team in tech!
One thought - with the fan tester and the sound chamber in the same room, you probably won't be able to overlap testing (I assume the fan tester is relatively loud)
Or are they just too big to move further into the building through normal office doors?
Yeah, correct. You can't run any other tests at the same time as noise basically ever. Even AC must be off.
Comment for the algorithm
Sorry if this already asked but why hide the manufacturer name/model for the fan tester? I mean I know what this exact model is but I can't see a reason why you guys would want to hide it. Just curious, thanks!
What noise is so small you'd really need that, but noisy enough to care about it?

Whenever I see Steve in a full body shot he looks like he's a short guy, can't tell if it's just an optical illusion or if Steve actually is sub 5'10".
Look at the doors in comparison or other reference points.

Oh to be a fly on the wall when a car passed by at 0300 and ruined one of Steve's noise floor tests...

Have you considered for your testing methodology that some more "normal" points of data might be useful? It's fantastic to know how scientifically quiet a fan is, but it would also be great to get "sure this is XX dba quieter, but that's completely un noticeable in most people's environments".
Questions like this really dont make any sense.
Please understand, When someone without any "scientific" testing tells you a Fan is quiet, Its incredibly difficult to understand if that means quiet for you; In you're environment . If that dude lives next to a welding shop in NYC he might consider a fan to be quiet. ( Im exaggerating on purpose here) BUT if you take those fans and put them inside your suburban house without running air conditioning, they COULD be loud as fuck.
If you take the information and actually apply it, You will have a real understanding of how loud that fan ACTUALLY is. Sometimes you have to think for yourself, Instead of wait for your exact answer
@@youtube.really.stole.my.handle That kindof illustrates my point. NO ONE has an anechoic chamber they live inside of. I'm not saying don't tell us the dB level, I'm saying throw in some points of reference specifically for the point of relating to your personal situation. Not may people know the noise floor of their dwelling, but they certainly know if they are urban, suburban, or have central HVAC. Making one fan out to be better than another because it's 2dB quieter doesn't matter if that is 10dB below a "normal" noise floor, and therefore there would be no point in spending $20 extra for it. That's an important consideration in a review that is lost if you just focus on "this one is quieter".
