Soundproofing – Got the Jimmy Legs

Soundproofing

Heavy equipment

The contractor supply company delivered all the insulation and drywall needed for the soundproofing project on Saturday. They ran late, I'm lucky they got there before Buzz had to leave, as he was going out of town for the weekend. For some reason I thought I would be able to carry the drywall myself. But even if I could lift the panel, I'd never be able to maneuver it into the house, those things are unwieldy!

We moved 22 panels of 5/8" 4'X8' Sheetrock, at around 90 pounds apiece. This means we moved nearly 2,000 pounds of gypsum. No wonder I was exhausted afterwards (not to mention I was hungover and on less than4 hours of sleep). Why are these projects always so much harder (and expensive) than you initially think? Even when you try to compensate in your mind, the reality is always much worse.

I have no idea how we're gonna get the drywall into the basement, I'll probably have to cut it first (oh boy, more dust!). Actually I should cut an 8-foot long slot in the floor and just slide the panels through to the cellar. Hey, it's my house dammit.

(Whoa, I just realized the tape is same color as the blog. Freaky.)

It's all coming together. Tomorrow morning we'll receive the bulk of the supplies, but the smaller stuff I'm having shipped to my office. I just received my order from soundproofing.org, which is probably one of the worst-designed websites still in existence. It has no set template from one page to the next, has no understanding of image sizing, relies on Java-based menu elements that only serve to confuse users, and I think they're still using the BLINK tag! I think that's actually punishable by chemical castration now. But at least I have my soundclips!

These metal/rubber things will hold the furring channels away from the ceiling joists so the new ceiling won't physically touch the frame of the house. This should keep things nicely separated, assuming I don't screw something up. The green stuff is padding tape, which I'm gonna put on everything I can until it runs out. This will further separate the new wall/ceiling layers from the existing framing. The stuff in the big tube is acoustical caulk sound sealant (made in my hometown of Mentor, Ohio!), which is just caulk that always stays flexible to absorb vibration. A few more pictures on Flickr. Maybe this will be of some use to somebody else out there, it seems hard to find actual photos of a lot of this stuff (as I said, the soundproof site is incredibly bad, much of the time if they have a picture at all, it's just an artist's rendition of what they think an item looks like).

I'm kind of worried about how we're going to get all the drywall sheets into the basement, some may need to be cut first. But that's pretty easy to do. I just hope the forecast is right (for once) as I don't' relish having to lug 22 4×8' 90-pound sheetrock panels through the rain. I feel very motivated to complete this project, not only so I can start playing the guitar again, but also so I can get back to dealing with the remaining orange parts of the house.

She'll ruin you like she ruined me

Saturday was a busy day in SoBu (South Bushwick, think this name will catch on?). We hit a snag with the plans for soundproofing in that my research I discovered that the air cavity we'd end up with would be maybe too little. Essentially, more air space means more sound isolation. It appears to go again logic, but we need fewer layers of drywall up there to get the best results. Please consult this handy diagram for relative STC (Sound Transmission Class) ratings (higher is better):
By keeping the original ceiling intact, we'd have a "triple leaf" which is less effective than a correctly-built double leaf. Of course, we're not really building a full double leaf (which would involve two sets of separate joists and is something that doesn't really fly for a ceiling that's only 6.5').

Ripping a ceiling down is fun. It took like a half hour to rip out some 150 square feet of double-layer drywall. It was a little tricky getting it out from around the pipes and conduit, but everything came out fine. Before we knew it, we had exposed all the joists (that probably hadn't seen light in 30-some years), happy to find nothing rotten or any human skulls or anything. The downside of course was the clean-up.

I had like 5 contractor trash bags left and those filled up within minutes with at least half the floor covered with rubble. Lucky for me, there's a contractor supply place two blocks away (Henry Distributors, 1674 Broadway) that sold me a box of 100 for $30. We bagged up the rest of the debris and Buzz started hauling the bags outside. Our cellar has those horizontal metal cellar doors with cement stairs leading down. While this is way better than the hole-and-ladder configuration most houses have, the stairs are really steep and the clearance of the doorway is minimal. And these bags were really really heavy. I don't know how we got all 10 (!) out onto the areaway so quickly. We basically were done in two hours (though it would take four hours to begin to recuperate for me).

As of Friday all the supplies have been ordered, most of which will be delivered Saturday morning. I'm annoyed with the new snowfall, as it almost definitely means nobody will be showing up today to pick up the trash, and it means it the plywood I've been storing out back will be all snow-covered, and I need that stuff indoors so it can dry out. There are still a few things I'm not sure how we'll handle but at least we're getting there.

The rest of the evening was spent going to the early show at the Knitting Factory to see Trans Am, Oneida and Big Bear. I wanted to go to this show because I really like Big Bear. But I was disappointed by the set; one of their guitarists left the group and appears to have been replaced by some keyboardist (red flag!), and worse, the lead singer is no longer barking in that shredding 'hardcore' screamo voice and sounds now like a little girl shrieking into the mic. She mentioned something about being sick, but it occurs to me that she says this at nearly every show. And wouldn't a cold actually make a voice more guttural and scratchy? I guess singing that way has finally taken its toll.

Oneida was good, as usual, but I don't think I like seeing them at clubs like this. They played some old stuff like "All Arounder," which was always one of my favorites. They didn't play "Up with People," which was fine with me, I'm getting a little tired of that one. We went to Nancy Whiskey Pub at the early hour of 10:30 and somehow stayed until the bar closed. There was a bacherlorette party going on there with a lot of sorority-types present. At first irritated by their presence, we concluded that it was admirable for people like that to have a bacherlorette party at a bar known mostly for its grizzly old men who hang out there.

Oh God can't you keep it down

Soundproofing the Cellar, originally uploaded by Jimmy Legs.

Since I'm no good for regular blogging anymore, let's get back to house renovations. Actually, 'renovation' may be too strong a word for what we've been doing to this house. I always think of renovations in terms of totally ripping stuff out and putting in something totally new, like a bathroom or kitchen. In this case, I'm trying to soundproof a room in the cellar so the band can practice without making the neighbors throw bottles at our house (well, they already do that, so let's just say we'd like to limit the number of things flung houseward).

At some point in the past the basement was paneled and subdivided into a few small rooms. I took the two in the middle of the floor and removed the dividing wall (which, like all the paneled walls here were single-stud frames with paneling nailed to it). These walls will provide a base for the soundproofing to come, but it's the ceiling that has been taking up all my time lately.

Once upon a time, this ceiling was completely finished in acoustical tile. By the time we moved in, though, many of the tiles had fallen out, and those that had stayed put were water stained and hanging by a thread. There had been framing around the pipes running through the room, not to mention occasional framings that didn't seem to be concealing anything at all. This led to my theory that the whole cellar had been designed to thwart anybody over 5' 7", since as soon as you think you can stand up straight you inevitably smash your head on some box or something sticking meaninglessly out of the ceiling. In retrospect, the Fuck Tall People Party was kind to the long n' lanky set.

So I had to rip all this stuff out so I can put in a partially decoupled ceiling composed of a dual drywall layer separated by a visoelastic adhesive and sealed with acoustical caulk.* The walls will be simpler, just a dual layer comprised of plywood and drywall (plywood leftover from the floor refinishing). I had planned to rip the ceiling down to the joists to fill with insulation, but I just realized that above the tile level the topmost layer is already two layers of drywall nailed into the ceiling joists. In theory, this is a great start for sound isolation, but there's one big problem. Or, several big problems, it's full of holes.

Sound isolation (the more correct term for what I'm after) is all about sealing things off. No matter what materials are used, if things aren't securely separated, the soundproofing won't work. Two layers of drywall is great, but the gaping holes (from old light fixtures and BX cable) negate any good the drywall could do. At first I thought I'd just tear this stuff down, but upon reflection (too lazy) I've decided just to patch these holes really well and build onto them.

I patched all the small holes last night, and a few of the larger ones. Tonight I tackle the really big ones, for which I have to construct plugs to mount into the boards. The good thing about this work is that I don't have to be neat at all. As long as the seal is solid, it doesn't matter what it looks like since it'll be obscured by the next ceiling layers. When it's all done then, we'll have two discrete segments of doubled-up drywall and two distinct levels of trapped air as well (as long as it's contained, that air will actually help stop heavy bass tones from ruining someone else's enjoyment of Deal or No Deal upstairs).

*I'll explain this when I get the supplies in.
