Hey guys, with your transformer using a rubber mount is probably not the best idea given most TXFR weigh a significant amount and the rubber will deteriorate overtime. Using a steel wire rope mount is probably going to give you a much longer and more durable solution to the rubber mounts. We used them in the military on naval ships to help protect the servers from the vibrations of the ships, and now I see them in the energy sector as well. As an idea of what I am talking about just google "steel wire rope isolators" Additionally you should do the same for your sever racks so the vibrations do not transmit through the flooring which isn't isolated. At industrial grade recording studios you will often find that the floors are actually floating to help prevent those transmissions through the floor. To help deaden the floor reflections you could also place some rubber thick gyms mats, or carpet with a good underlay. Hope it help! Cheers, Duke
It’s honestly just the isolators inside. More often then not the installer forgets to loosen them after installation. They’re tightened down hard for transportation and it makes a huge difference.
This is great advice, which LTT will happily ignore in favor of worse DIY solutions that allow them to make more profitable server-disaster videos in the future. (Which I'm fine with, I love these server "vlogs" xD)

@@swankshire6939 isn't that just how job delegation in general works? You hire someone for something, they do something. Sounds like you are trying to imply Linus is lazy, idk what you meant by that.
@@swankshire6939 yes because the higher ups are doing the things that make it possible for the guys at the bottom to have work to do in the first place.
@@darylphuah I can see his criticism, sometimes higher-ups do contribute nothing, but he said that in the context of an LTT video. It's Linus man, I've been watching this Canadian lesbian for more than 10years I think, this dude works.
@@bilateralrope8643 Just hope when they do that, they install fail-safes so they can remove it, in case it gets a bit.....unruly. You don't want to go to remove your Alpha AI Core and find out it's not there. 😉 I guess it's better than dealing with -redacted-.
I love these vlog style building episodes because it shows how talented the team is…not only a great group of nerds, but great group of handymen as well
Gentlemen. With all the love in my heart, may I simply say.... PLEASE WEAR A MASK WHEN YOU USE ROCK WOOL! I work with it every day. It's invasive to your respiratory system and can cause all sorts of problems. There's no shame in being safe. We'd like to keep all of you around. Keep up the great work and content. ❤️
Can I just say that I adore the Labs Server Room Saga. Every video has been a complete blast to watch. Even if it's the kind of thing barely any of us watching would ever have cause to use, it's just satisfying to watch them. Must be that same itch that gets scratched by watching DIY videos. And Random Dan is always a win. I too wanted to feel the fabric and see how soft it was. Be interesting to learn when Labs finally breaks even. Thought I think we all know that is a long way off with the price tags of just some of the stuff they've bought. But I do love the amount of in-house design that has gone into making it work. From the hangars here to the refined testing gear. Really shows how immensely useful 3D printing can be in a work environment for those of us in industries where it's just not used. Have a crazy idea for something that might improve workflow? Just run over to the 3D printing lab and bash one out.
As a System Admin for a government agency, I can assure you, you have the most organized server room I’ve ever seen. Every time I walk into my main office’s, I want to cry.
I usually find server rooms like pretty decent when they're first put together, 10 years later with random patch changing and equipment swapping and they look like trash (source: work in schools)
@@PC3Pointless You forget the Upgrade which didn't fit into the rack and now has a swinging wire so that the Server is now on a small table, this wiring is called 'Ape Swing' to it cross over the Room, as there were no Money for a Cable Board to have it on it. (Source: Work in Schools as well)
@@panzer3279 because, from the context of @pyroslev comment, I assume DIY guys just slap some stuff around HVAC unit and HVAC service guys have to play around and do some weird movements to actually get to the HVAC. I assume.
@@panzer3279 Probably because the DIY "Solutions" get in the way of them doing their job or they have to spend extra time moving or fixing these "solutions".
Have been researching DIY multisplit aircon install guides for my home and there are a lot of details to overlook. All video guides on RU-vid are filled with comments that the video missed. I am going to let a professional HVAC installer handle this one, I think.
A cheap kitchen bread knife is how pro installers cut rockwool. Gaps, even tiny ones, are your biggest enemy in sound proofing. The drop down door sweep is an excellent add. Great work!
I work with rockwool with metal net one side (as pipe insulation so it doesn't fall apart that easily) and I use big garden scissors (basically a straight hedge shears)
this is exactly what I was told to use when i used the safe n sound rockwool to sound proof my basement. the cuts take a few seconds. stuffing it in every gap.... well that took a long time, and i'm sure i didn't do a pro job, but it still made a huge difference compared to having none before i finished my basement.
Shoutout to Red Green! I met him in Washington years and years ago, he's easily one of the nicest and most polite people I've ever talked to still to this day. Just an absolute saint
I'm sure that between dan and the audio guys from the lab they already know that proper sound proofing requires an air gapped room within a room on all dimensions. they only spent 2000 dollars on this, worked with what they had (existing electrical, ceiling tiles, and windows) and still managed to block enough direct sound to make those rooms tolerable, as someone with experience in this industry, i call this a win.
It's a "win' but it's jank AF and I find it frustrating that such a limited approach (partially effective, but 100% half ass) is promoted by someone with as much reach and impact as LTT. :(
@@davidmoffitt981 I understand but they likely didn't need to reduce as much sound as a proper solution would do. They could probably get another 10 dba if they need it just by doing something to the ceiling tiles and tightening the doors up a bit more. Contracting even a small soundproof room can go deep into 5 digits, and then the video wouldn't have been as fun. Their elgato acoustic panel video on the other hand was horrific. I'm actually ashamed that their huge channel promoted such crap.
@@davidmoffitt981 how is it jank? It was the cheapest job that met the specifications and it will last longer than the room is needed. Spending more than you need, is more jank than spending just enough.
@@jaydensydes3478 considering that they contracted for building an actual acoustic test chamber, you could bet even Linus and Jake know what it takes to have actual sound proofing. So they knew exactly what they’re leaving on the table going this cheap
On the final graph, it looked like all the significant peaks were just harmonics from the transformer, will be interesting to see a graph once that has been solved
I noticed that too! That’s great news for them once they solve the transformer noise. Side note: I’m kind of puzzled why the second harmonic seems to be entirely missing in the second reading, but returned after the rockwool was installed 🤔
Oh wow. I didn't notice it right away, but now that you mention it... There is clearly a second, thrid and fifth harmonic* on the graph. (* harmonics in regards to the 120 Hz of the mechanical forces in the transformer, not of the 60 Hz grid frequency)
For the door. Make another wall. Can be 2x2s , leave a 1/2 inch gap between walls and use soft foam strips between studs and original wall. add another door, leave 1/4 space between the jambs with some more foam. Use a solid core door and preferably use soss hinges to gets really tight reveals. And also install weather stripping on the door stops trim, make it tight.The drop down weather strip is spot on. And remember the way to defeat sound is not just adding sound barriers, it's also changing the mediums, types of materials, off setting openings, the goal is to make the sound not go in a straight line. That's why the gaps and foams and material density.
It would be kinda nice to get a tour of all of lmg when this ( I don’t want to call it project) is “finished”. With all your hard work would be amazing to see another update on who things rund and videos are made
The goop is essential to ensuring you don’t have a rigid connection to the panels. I think it would also be interesting to see an NIC/ASTC comparison of the wall before and after. Love to see y’all getting into acoustics!
I love these type of videos so much. I could watch this stuff all day. This is the type of work that I feel like would be so much fun to do and so satisfying to see the end result. Love the 3D printed solutions you used too, that was super neat to see.
Agree I was thinking this the entire time. Granted that's part of what the insulation does is trap air, but disconnecting the sound-conducting materials is always a great step to sound-proofing although potentially much more expensive. Floating walls, floors, etc. In general people vastly underestimate the insulating properties of air both sonically and thermally. Air OP.
If you're ever using Duv again, it's actually meant to be able to tear in a straight line. If you start tearing it, it'll tear all the way down the roll in a straight line for ya. It's super nice to work with. It's a very common thing in theater
I guess Linus never had to consider the noise issue for his house because the room with his server is much bigger. Not to mention that there aren’t nearly as many running electronics making noise.
I think you are forgetting the workloads here. At home Linus has some PCs I think a NAS and thats like everything. Its a single rack, in the basement. At the lab there is more than a single rack, this leads to like double the noise. Also its literally one room over in the lab and at home its on an entirely different floor.
Speaking about the OSB boards: Shouldn't those be in EVERY inside wall? One layer or OSB, one layer of drywall. That way you get something actually sturdy work with so that you can mount regular stuff on every single wall without worry, and you still get the fire-proofing from the drywall.
Great ideas here! Something I would suggest for next time, is making sure when you are using a fabric to cover your mineral wool sheets, make sure if you blow through it you can feel air coming out! Sort of like the front mesh of a case, if you can't feel air going through, the air flow is crap and waves will be reflected rather than passing through your fabric and being absorbed! Also, having an air-gap between your panels and the wall does dramatically increase the efficacy of your acoustic panels, rule of thumb is at least 1 inch gap per 1 inch thickness of acoustic panel. A 3 inch panel would be most effective with a 3 inch gap, and this rule of thumb is effective up to about 6 inches, after which you start to see diminishing returns. Much love guys!
Server room content is some of my favorite that y’all do. I know NOTHING about servers or configurations. I hardly know what y’all are talking about half the time…. BUT I LOVE WATCHING THE SERVER ROOM SAGA. 🤘🏻
he’s definitely not a regular craftsman lol, at like the 2 minute mark he thinks that you have to find studs thru drywall by randomly hammering in nails until you hit a stud. there’s a tool for this & it’s literally called a stud finder lmaoo
I saw light switches in the server room that you just cut away the insulation to allow access to them. If you can access the outlet from the backside ( from the room behind that wall ) you can use sound deadening putty sheets you can cover an seal the back side of the outlet box and greatly reduce the sound leak through the electrical outlet/switch boxes.
Linus keeps subtly dropping those "upcoming cable management arches" and I'm over here, wallet in hand, dust settled on my shoulders from _waiting for years already._
At Menards in the midwestern US we have Homasote board that is a recycled paper product (1/2" x 4' x 8' or should I say 12.7mm x 1219mm x 2438mm) that deadens higher pitched sounds through walls. It doesn't absorb, more it just doesn't let it flow through.
My coworkers friend used egg cartons he got from his local bakery and restaurants, since they didn't want it and he was kind of like recycling them, it was a sweet deal for both parties. No idea how effective they are though on sound proofing😂
This is a myth, as an acoustician I can tell you they do almost next to nothing for sound insulation and have a minor effect as a diffusers or on reverberation time.
Yes, they would be. It's not asbestos (shattering into pointy Crystals that cut trough any protective scar tissue lungs might develop) but it's not good. The wood is bad enough with long-term exposure but what's effectively Glas dust is worse
Coming from a carpender interiour worker i can tell you, the very best way to stop sound is by mass and that means, double layered drywall and with a small gap betweeb you do a second one sided dry wall in front of the first one. For best result you also do a second door. There also specal drywall plates available for sound proofing but they cost most of the time more thsn just doubling up with normal panels. Also they are heavy as hell, so working with them can be a pain if you need to get them somewhere by hand.
Btw its very easy to understand when you look at how windows are made for different soundisolation levels. Dtsrting with 2 glasses same thickness, going to three glasses, to three glasses with a different thicner one on the outside to having at the highest sound proofing class a second window in front of the firdt one. Quiete rare the last two classes but they exist.
Probably even better is a double 2x4 stud wall. Frame 1 normal wall then rockwool insulate. Then a 1" gap and a 2nd insulated stud wall with studs shifted 8" left/right so stud spaces aren't lined up in 2 walls. Then the soundboard as shown here the green stuff(Sonopan). Then 5/8-3/4" drywall. Then drywall hat channel (sort of A shaped steel channel installed perpendicular to studs) then another layer of same drywall. Dense mass like thick drywall helps block sound. The air gap between walls helps block sound and vibration transfer as well as the gap between layers of drywall.. That all will give an excellent sound deadening wall.
You're actually doing this right, for the most part. It's like watching that second square hole girl video, where the guy puts the shapes in the matching holes, instead of sticking them all through the square hole.
I would personally do 3d printes spacers between the OSB and that Green wall thingie. Just to create an 'air gap' to trap vibrations and sound waves further. Before doing anything more. There is a reason, you tend to build two walls separated with a space in apartment buildings for sound dampening reasons.
I'm always curious why he never uses MLV (mass loaded vinyl) for these sound deadening purposes, it's so much more effective for directional blocking than insulation and such.
@@Xavier_Wells I can see that, but between specific fasteners meant for it (or 3D printed solutions like they're using for the other stuff) or simply sandwiching it with drywall (or even the same soundproofing board they're using), it shouldn't be an issue. It's definitely more difficult to work with than the stuff they used, but also more effective in my experience.
I never realized how spoiled I was coming from a data-center environment for 25 years. One of which was run by a hospital so we benefited from their massive filtration systems. I never realized the struggle lol.
For the wall, resilient channel is a great product to use to minimize sound transmission without using so much insulation. It is widely available in the Lower Mainland.
As someone who is in the data running and server building industry, that server room has good potential, not how I personally would set it up but it works
Yes, most of your noise WILL be still coming through the door. Have you considered adding a vestibule to your server room? Also sound curtains within your room will also cut down on much of the sound that you're still dealing with.
9:23 That sounds like a classic rookie story we all get while learning. Mine was clipping a live wire(120V) an taking a gas station down to the point they had to turn customer's away. Thankfully it was fixed by flipping the breaker.
I work with sound level equipment in relation to human hearing. Normally we refer to the amplitude of sound as SPL, or dB. Our ears however don't hear sound frequencies the same way as microphones. So we use an adjusted scale called dB HL. The HL (hearing level) refers to the fact we hear different frequencies with different efficiencies. Long story short, you can have a very loud low rumble from a fan that you simply don't hear very much. But a microphone from a sound pressure meter is going to register as a very loud noise. Same goes with high pitched sounds.
The mechanical door seal and Rockwool insulation were featured on This Old House & AskTOH, so I'm pretty familiar with those, and would likely use them.
That's basically how many clubs (at least used to) sound-proof, to prevent noise leaking to outside... One I worked at a few years did it pretty much this exact way and combo :)
So I would have also added "Green Glue" It's similar to that seal that you used but goes on like paint. However it dramatically and I mean dramatically cut sound levels. It's used a lot in high-end offices.
I once worked at a place that converted an old commercial refrigerated room from the 50s thst used 2 ft of cork insulation into their data center. Was amazingly quite outside.
So audio wise for anyone who is interested. Db is just the scale it gets measured in. Here we are talking about DB DPL. The sound pressure level measured in the db scale. "DBA" and "DBC" are known as weighting. It is a literally just a eq profile that it measures. So if this helps anyone DIY their setup cool. Your measuring the SPL (Sound pressure Level) using the db scale and then using your appropriate weighting a b or c.
Did you all look at Mass Loaded Vinyl at all? It’s a great way to stop sound transmission as it’s super dense. Works great in recording studio and home theatre construction.
Oh dont worry about it, some IT people are too uptight about cable managment. I posted some pics on twitter once and everyone and their grandma was dogging it, but it was fine. The ports on the patch panel were labeled so I could find what I needed just fine
My first job had to do with computers. They offer me the job and the day I showed up for work they showed me this large computer room. It had IBM, Honeywell, Vax, and Prime mainframes. I had only seen 1 computer in my whole life. I though wow they are going to fire me on my first day at work. Then my new boss showed me the communication room. This is where my background came in handy. The room looked like a drunk spider install all the cables. I learned a lot working on that communication room.
All seems great and dandy, but when you stop to think about it, the FR material is held up by magnets. Magnets lose their magnetism at high temp...like a fire. So the FR material will more than likely fall off if you have a fire, defeating the purpose.
