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. ❤️
it looks like they were wearing covid masks for a lot of that part, better than nothing
In short - don't kill yourselves too early cause we'll miss the content.
Literally every time I see them doing any construction type work, I'm just internally screaming, "Holy fucking shit, put on some masks!"
They will make LinusAI.
Not saying that you are wrong (because you aren't) but there is a big difference between working with it daily and doing a couple of days work.
I feel like in 20 or 30 years, that thing'll really come together nicely.
Once the entire rack is 10 generations obsolete
CZcams themselves asked me for feedback on your comment.
Imagine they just have a whole ass data center by then. 😆
@@TheBenSanders "whole ass data center" What?! What exactly would that look like?!
In 30 years, these guys are gonna be configuring 256bit zettabyte servers that are running on positronic opticircuits and quantum foam processors.
The wifi will probably use wormholes.
Using the lab and it's resources to build the lab is absolute genius!
Just imagine the jank if they get an AI to run the lab.
@@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-.
gotta recoup that investiment lol
Carpenter here! Rockwool has a more rigid type of the insulation called ComfortBoard 80 that is basically a mix between rockwool insulation and sonoboard. May have been a product you are aware of but if not, we use it all the time and it's fantastic! Could be a product to keep in mind next time you take on a project like this. Impressed with the work you guys did though, your DIY is better than some of the professional stuff I've seen haha. And also, f**k acousti-seal, all my homies hate acousti-seal
This or Owens Corning 703 (or OC 705) works great for first reflections and bass traps, but is likely not any better than plain batts (safe and sound, or plain old pink stuff) in a wall cavity.
I've used ComfortBoard to make DIY acoustic panels. Excellent product.
Ditto on that butyl acousti-seal. I've switched to green glue and usually just use Big Stretch. Similar effect and no mess.
Linus to LMG employees: "I want you to help me build this company"
LMG employees: "business-wise, right?"
Linus: "you're gonna build the business alright"
Please put this on the Anakin and Padme meme, please and thank you
Yeah that's how every company works. Higher ups want something and it's the guys in the bottom who actually do the work
@@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.
Always love to see Linus and his Son working on the server room 🥰
Don't you mean Jake and his son?
You realise that Jake isn't his son, right?
Yeah it's not his son, it's his wife's husband's boyfriend
Jake seems to be keen to sexually assault other men. I always suspected that about him.
looks more like luke´s son. oh shit
I love that they are all doing this themselves. It's their style and I friggin LOVE it
The calculus for them is easy. They save some significant amount of money by doing it in house. And they make some money because they made a 1M view video out of it. And the opportunity cost is low... because they made a video out of it. The cost-benefit of DIY leans really heavily DIY when you make money from it too.

"Every time I see Dan I'm like what the fuck is wrong with him? but like in the BEST way"
This is how I want my friends to see me
Yup, definitely GOALS
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
i had no idea what steel wire rope isolators were and now I'm fascinated by the concept
That is super cool. Never heard of them before.
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.
There’s also a bunch of other ways a professional electrician could solve that, rod transformer hangers and just proper ground isolators.
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)
I'll never not love Dan randomly showing up in episodes and just being Dan!
Yeah, me either. :/
He's so lovable. Every time he pops in he looks so happy. You really get the feeling he just adores his job.
Dan's gonna Dan
Dan just has all the intrusive thoughts. but it's offset by his high value of knowledge.
Dan is computer Sheldon
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
But they also show that it's not that hard to do it yourself, if you just take some time to research the material and stuff :)
i love the "noncontent" of the channel.
when there isn't computer tech news, or inventions, the youtube is just vlog style building upgrades like linus' house, the 5,000$ tech upgrades for the team, and so on. Keep up the great work!
I like when LTT does this kind of IT stuff. Really interesting
This is not even IT stuff. Insulating walls is something everyone could do at their homes. Those materials are also good against humidity.
@@rodryguezzz r/whoosh
@@rodryguezzz dude shut up. What a ridiculous comment.
What is the joke in it?
@@rodryguezzz those materials are NOT good for humidity. Sure in some places but in actual humid, hot or rainy places no.
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.
can't even imagine how it looks like🤡🤡
@@politecraft it looks like job security.
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)
I worked IT for a school. It was somethin.
I love seeing how far Linus and his servers have advanced over the years! It's some of my favorite content on this channel.
It's so nice to see this deployment! I've been looking at sound solutions for a while and sonopan and rockwool was what I was planning to use in my walls (when I get around to it) so this let me see a deployment of that solution!
Thanks LTT!
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. :(
No one died and stuff works. That's a win.🎉
@@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
As someone who works on HVAC and has to deal with DIY and DIWHY, thank you for leaving the area around the unit serviceable.
Why are HVAC guys against DIY?
@@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 CZcams are filled with comments that the video missed. I am going to let a professional HVAC installer handle this one, I think.
I love these kind of videos. As someone who is a home-lab enthusiast, its fun to see what kind of solutions are out there for this kind of stuff.
Third times a charm. LTT has learnt quite a bit over the years, and are now putting those lessons into play. What I like to see.
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've been working in construction for a year now and this explains why I keep finding cheap kitchen knives in buildings with rockwool
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.
I love Dan. Even when he is just in the video for 5 seconds. ❤
It is always a treat when a wild Dan appears! Specially for the projects like this.... Linus need to start doing more in his house, or buy a new one again, so we can more Dan content like this!
@@Krydolph I'm still waiting for the pool.
dan is dandy
@@Splarkszter From what he told so far on the WAN show, it sounds like its a complete shitshow. Also that he hired "professionals", very bad professionals!
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.
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!
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 doors, you should check complete soundproof solutions. Here in Finland, Swedoor’s Rw 47db - class doors are so soundproof that they block practically everything. I’ve used an angle grinder to cut metal and the person on the other side of the door, just barely heard it. They’re also fireproof.
Also thought that that door is just crap. Looks like it has a fire proofing rating but then there are freaking GAPS. A fireproof door should be almost airtight?! How can this withstand 90 minutes of fire?
@@thoreberlin A fireproof door has to withstand fire for 90minutes or so. But to get it airtight, in Italy/EU a fireproof door has to have automatic "pyro" activated bars that lock the door from opening, also has a "foam" thing around the door that expands with heat and get it airtight.
@@giacomobertani6203 yoe can get both F60 and F90 doors without fire expansion foaming. That stuff is mostly used for temporary cable ducting.
for sounds, 2 patio sliding doors works wonders, you just want the air gap to be sealed and that kills damn near all the noise you need it to.
@@thoreberlin While I don't know about this specific door, some fire resistant doors have foam at the bottom that puffs up and closes the gap when it gets hot. For it to work properly the floor below the door must have a metal bar that the foam can expand onto and hit.
Thank you for an interseting video on a project that was done WELL. This is the quality of content that i want more of.
Man I love this i'd watch this kind of stuff all day long, so relaxing and just entertaining!
I’m a programmer, but I find all the hardware stuff fascinating, including on actual buildings.
Programming is not all about software.
To write good software you need a deep understanding of the hardware.
If as a programmer you weren't interested in the hardware then that would be a really bad sign.
@@MaritimesNB I’m not experienced - how can you tell if they are bots?
@@sjzara Usually they're accounts that have attractive women in provocative poses with equally provocative usernames. I've also found that some bot accounts use other bot accounts to give their original bot comment a ton of likes. I've seen some comments that were posted less than 20 minutes ago with hundreds or thousands of likes.
@@shapelessed By hardware I mean the building.
@@shapelessed What would you say about the reverse? Because personally I have almost no interest in software beyond the stuff that I need for hardware monitoring.
I've watched every single one of your lab videos. They are SO entertaining.
Name every single ltt server video name then
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
crazy you could hear the diffrence with just them talking in the room from the beginning to the end. I love these project videos!
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
They do tours as part of LTX but yes I agree as I can't afford to go 😂
This will 100% be done
...finished...? As if.
It won't be finished until the building falls down. Maybe not even then.
If you creat an air gap between the "sound deadening" material and the wall it will work a lot better.
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.
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.
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. 🤘🏻
My absolute favorite series are the server room vlogs😍😍
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.
Good seeing Jake again. And he looks good. Fantastic work fellas.
I'm surprised that you were not overlapping gaps, that is usually how I would do insulation, also I love everything about this clusterfine
Always love seeing the infrastructure & server room content guys. Highlight of the channel for me
Btw, thanks for being there for me. I had 🐶 years and you been there for me it’s help me sooo much. I get it you just doing you things but for me it’s been a major part of my life. Thanks guys. Keep it going. You make a difference
I relaly enjoy the server stuff. As a student in networking, it's always interesting to see what solutions companies have to different problems.
I wanted to see the duvatyne covers fully in place. The magnet idea is really cool, it'll probably look incredible. Hoping we see it in the follow up video with some cable management.
Using the magnets on the washers is pretty brilliant. Good one, whomever thought it up!!!!
So happy you cleaned the window Jake!!! Good on ya.
Server room vlog is one of the most chaotic and fun things to watch
I used the Safe N Sound for insulation panels in my vocal booth for voice acting. Worked like a charm and the room sounds amazing.
Even though I have been a subscriber and watching for years, this is the type of video that if ever recommended to me as my first introduction to you would have solely captured my interest and sent me down a binge-watching of the channel.
These server room/building videos are my favorite videos from LTT
I love how much effort they put in for their employees health and well being.
Massive quality of life improvement, and really, not ALLL that expensive. Bummer the green panels aren't more widely available, but wow what an improvement!
I've been watching sound proofing videos for about a year, and been jealous of that Canadian green paneling... "Home RenoVision DIY" channel is pretty good for sound proofing ideas and guides.
Having worked with rockwool before i’d wear a long sleeve along with those gloves :p
Nice video keep up the good work LTT team!
One of my new favorite LTT videos.
I demand more audio/room acoustics videos! Please do the whole studio with measurements at various stages!
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
It's definitely a good idea to leave a little bit of that window open you know for those times you're in the server room during a power outage.
in 2023 we have these things known as flashlights fyi
In commercial buildings, any room without a window is required to have an emergency battery powered light. The details of that requirement varies from one state/province to the other but usually goes around those lines. So, if they would have blocked the window entirely, they would have had to pay an electrician to install an emergency light. Good call on leaving part of the window uncovered.
You guys amaze me more with each video
Lol love the Red/Green nod to the duct tape. I loved watching that show growing up. Though it was on kinda late on PBS where I grew up.
Always a good day when Linus uploads. Especially the shenanigans that go on with the server room.
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.
That and I believe every floor is concrete
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.
That's gonna change when he turns all his computers into 1u racks and there'll be like 5 of them
the speed up montage part is really neat, i liked that very much
Never lose your passion for DIYing through trial and error
Whoever edited this video (Yes editor is at the end of the credits, I know). Did a really good job with the pacing and how the video is portrayed. I feel like I am watching a home improvement -esque video but it's LMG being themselves.
12:00 Dan is the absolute best 🫶
This series Will never end.
I used all of these materials (and more) when I built my last home studio 20 years ago. It works.
Server room is the best continuing storyline in the LTT universe.
Jake is by far my favorite "host" at LMG. Sometimes the things he do and say, I can relate to as an IT support person :D
Best video of the year from LTT 🎉
I was very happy to hear to the red green reference. I'm not Canadian but I watched red green all the time with my dad growing up.
If there's anything I admire more in Linus than the fantastic crew that he's managed to assemble, I would not know what that is.
Every project Jake is involved in is well thought out and executed to perfection. He’s a great member of the team.
Jake is Linus's right hand man for sure
There's a product called Silverboard for sound and heat insulation. It's basically styrofoam sandwiched by foil layers on both sides. I originally bought it to cover my windows because of a neighbor's barking dog, and it worked great. I cut it to size and pressed fit it into the window frames on that corner of my house. Then I also noticed it was a lot easier to heat/cool those areas so I filled in more windows and my electric bill dropped dramatically. My house has way too many windows and I like to sleep late so it worked out eliminating so much sunlight. The Silverboard was hidden behind my wooden blinds so I started leaving them in place year round. I can barely hear anything going on outside; barking dogs, screaming kids, lawn mowers, etc. That also meant I can turn my guitar amp up to "patent pending" without any complaints.
Every time I see a server room video with Linus I’m hooked something about this topic😂
box extenders over the lightswitch would be a huge upgrade
A wild Dan has appeared again. Always makes the video a bit better.
Good work major improvement from before using all the right products this time, Home Renovision would be proud
They did improve, but it is far from done right.
Given that I'm currently designing my studio this video helps A LOT!
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!
I always love Jake's unscripted word choices 😂
These are my favorite types of episodes haha love it!
I soon as I heard we were soundproofing, I immediately knew it was Sonopan and Acousti-seal lol what watching fellow Canadian Home Renovision DIY nets you. Only wish it was more widely available here in the good old US of A lol
Looks like the best thing they could have done when constructing the room was make it 2x6 thick but use 2x4 and stagger them so that none of the 2x4 studs connect to both walls. Its called an airgap. Its usually done in condos to keep sounds isolated. With that and the insulation he is using would be bulletproof for sound.
^ THIS. It's so effective, I'd redo the project to incorporate it.
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. 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.
Jake is back-was just thinking about how I missed seeing him and Linus do their father/son thing!
Which one is which?
Also, Jake has grown up a lot during the last five to seven years. He was very young to begin with but he's definitely mellowed out.
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 always love a Jake server video.
Funny stuff all round, great vid.
I can’t believe they have a festool tracksaw as a tech/media company. I’m so jealous
That's Alex's tool, it's very handy. We've used it multiple times here in the last month 🙂
Scrubbed all the comments looking for someone talking about the casual festool track saw 😂😂
Isn't rockwool bad to breathe and handle without PPE? Or am I missing something?
i just love these server room vlogs
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.
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._
I completely forgot about them. I just remembered that they did showcased them quite a while ago but I haven't heard anything since then.
linus not wearing a mask handling any of the material clearly letting off particulates 💀
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
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.
Production quality on LTT videos are literally unmatched.
The big difference that actually helps with soundproofing you guys seem to miss is separating the room from the walls/floors. You need an air gap combined with the dense materials to make a difference. Also put bass traps in the corners to help with your low frequencies. You can build them out of the roxul.
If they've got Rockwool on every single part of every wall, including the corners, then bass traps aren't necessary. The potential for sound (of any frequency) to bounce off the walls and corners is already reduced a ton.
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😂
Ehhhhh, well, at least he got to help the bakery dispose of their waste and he also got to do some fun arts and crafts at home. That's about it.
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.
Now i reeaaaaally need a music production/music recording video setup, the entire thing was freaking amazing
I got so ingrained in the sound proofing materials that I didn't expect the segue 3+ minutes in!
