**Testing for Noise Cancellation: A Comprehensive Approach**

In order to test the noise cancellation capabilities of our system, we decided to take a unique approach that deviated from traditional methods. Instead of using ISO 3744, a standardized procedure for measuring noise levels, we opted for a more hands-on approach. We set up a hemispherical mic array with 10 microphone positions, each one meter away from the device, and then moved it several inches to capture different measurements.

**Understanding the Importance of Noise Cancellation**

Noise cancellation is an essential aspect of computer system design, particularly when it comes to creating a quiet environment for productivity. Some users may prioritize silence above all else, while others may focus on optimal airflow or prefer a custom setup. Our system's modular design allows users to choose their preferred configuration, ensuring that they can tailor the system to meet their specific needs.

**The Challenge of Quiet Testing**

One of the biggest challenges in testing noise cancellation is replicating real-world scenarios. In order to achieve accurate results, we needed to create a controlled environment that mimicked the conditions under which our system would be used. This involved setting up a testbench with the same hardware configuration as our system, but without the case. By doing so, we could compare the performance of our system in both open and closed environments.

**Simulating Real-World Conditions**

To put our system's noise cancellation capabilities to the test, we simulated real-world conditions by running benchmarking tests that mimicked typical usage scenarios. We used Prime95 to tax all CPU cores at 100%, as well as Unigine Heaven to simulate a standard stress test for a system. This allowed us to push our system to its limits and see how it performed under heavy load.

**The Results: A Surprising Find**

After two weeks of crunching numbers and analyzing data, we were finally ready to present the results. To our surprise, our system's noise cancellation capabilities proved to be far more effective than expected. With an average noise level of around 20-22 decibels, our system was able to achieve remarkable results in terms of quiet operation.

**Transparency and Detail**

In order to maintain transparency and credibility, we made sure to provide all the details of our testing process. This included creating a comprehensive spreadsheet with 12 tabs and 47 columns each, as well as sharing the full report of our findings. We also took steps to ensure that our test results were reproducible and unbiased, using an open-source approach to verify our findings.

**The Future of Noise Cancellation Testing**

As we move forward in the future of noise cancellation testing, it's clear that traditional methods may need to be reevaluated. By taking a more hands-on approach and pushing the boundaries of what's possible, we've demonstrated the potential for significant improvements in quiet operation. We're excited to see where this research takes us and how it will shape the future of computer system design.

"WEBVTTKind: captionsLanguage: enhey guys josh and we're here at work at labs today we're going to test out the define r5 and find out how truly quiet it is so this is the world's quietest sound room according to Guinness I think it's estimated around like negative 9 DB and if you look around you see all the acoustical baffles if you look down the floor is actually like a mesh great and it's actually somewhat springy so it doubles as a trampoline the anechoic chamber is constructed out of a double shell system so there's one steel shell with a door on that room that room is suspended on Springs then there's an air space all the way around and another shell of composite metal panels so we still have the heating system on for the anechoic chamber and with a quiet microphone we can measure that which is very quiet in there you can't hear it is between 5 and 10 decibels a weighted that's extremely quiet it's motion by it than most environments you'll ever be in but now I'm going to turn off that system and we should be able to measure below zero what's the really negative one point spider uses as its it's like minus one the reason why even though that's super isolated through there it's so sensitive and quiet in there that we can pick up us talking yeah it's just so quiet so now we might get yourself right that's because that's how much game you have what and it's still the owner can tear your clothes yeah that's still that whole thing right right but if you turn this up when the doors open you know it's game city should easily deal with a hearing the nice thing clearly right right thanks but then if you leave it up the bottom up and open the door yeah and it's quiet thing we're using ISO 3744 a hemispherical mic array which uses 10 microphone positions each position is at one meter from the device but over the surface of the hemisphere I keep moving it after inches so how many different measurements are we going to end up taking purse on each one 10 10 so you have to reset this five time times so it just goes to show you obviously when we construct the define our five you know it's it's basically it's a platform right the whole reason we have the module in panels is some people want to have optimum silence some people want to opt on the airflow and that's where we give you the choice you know some guy may not be as concerned if it's 15 DB versus 10 or 8 or whatever for the people are more focused on silence you can leave them all on you know in Puget when they want to go all in they do things where they come up with custom fan brackets that they develop they basically relocate fans inside the case for a more optimal airflow or this one is designed someone is an intake but more than anything it's going to direct air directly onto the graphics card so the graphics card is cooler so the graphics card fans don't to spin as hard so we are trying to be able to actually film inside the chamber and you have like a time-lapse or something with the test and both cameras we have here are actually too loud like normally if the case is like crazy loud or something that would make a difference because it's so much louder but because the case is so quiet the tiny tiny little noises on the cameras that do nothing throw it off just up it's crazy anything below about 10 decibels a weighted you're gonna have a really hard time hearing at all unless you're very close to it and there's two microphones in there and each one has a different value so though this is microphone number one ten point six microphone number two ten point five all right so out goes the full case and in goes the testbench so this is the exact same thing just obviously without the case exact same hardware configuration exact same fan number of fans and type of fans so it's basically apples to apples as close as we can get you know gear on an open bench versus gear inside the kids okay so as we're finishing up the other testing we're going to move into what we call Kelly there were viewers benchmark Jenny what most reviewers will tend to do is run a system based on thermal loads that the fans spin up so on and so forth and create a noise level so to replicate that we're gonna run prime95 taxing all cores on the CPU at 100% as well as run unit in heaven benchmark on top of that to simulate a guess you know a standard stress test for a system generally larger than what normal usage would be but kind of worst-case scenario so this is a probably the least scientific of our test the rest of them are all been the iso where it's very regimented what we do this were just trying to replicate what a lot of reviewers do so basically this thing's undergoing stress testing right now as you can see the the benchmarks still running and I think we're hitting like right around was it 20 ish 22 or so out there which compared a lot of our other test results seems incredibly high you know as orders of magnitude higher but then if you actually listen to the system you'll hear how loud it is right now under full load alright so it has been two weeks and we finally had the results so it was actually a lot of work we thought like we were there like oh just spit out the the thing get like 10 minutes there's a big deal yeah yeah it was a 60 test and then it was two weeks of crunching the numbers into what he considers a condensed form which still comedies during the spreadsheet uh there's I think like twelve tabs and there's like 47 columns on each tab it's like the SATs I I mean I didn't know what I was signing up we're just throwing this out there yeah yeah exactly don't bother invoicing so basically what we're gonna do is we're gonna post all the different results as part of the video well it's supposed to link to the official reports once we have those completing sperm there we go all the nerdy stuff yeah yeah exempt we're kind of go for like a full transparency thing here it's like obviously you know we we couldn't have done anything to nerf this test our favorites still maintain the iso compliance so we're gonna put all the details up there i mean you'll probably be able to see the 60 different tests if that's your thing and it I think we're done all right three because I was really like shaky yeahhey guys josh and we're here at work at labs today we're going to test out the define r5 and find out how truly quiet it
