Multi-Purpose Insulation???

[Mixteco]

I already know about Owens Corning 703 as a cheap alternative for sound deading & what not...but

I was in tha hardware store tha other day when I saw this thing in small lil rolls that said "Multi-purpose insulation"

I read tha back & it claimed to "sound proof." I don't know if this would serve good as something to use to soundproof a vocal booth in a bedroom, now, would it? Would it treat a bedroom acoustically? I mean it only costs about $3.75 here in town. Just a question for you guys...

Here's what I'm talking about (replace 'dot' with periods)

anyone???

Looks to be regular density fiberglass which isn't as easy to build or as efficient on the low end as the medium ridged stuff but compressed it into frame panels it would do fine. Here's an example of the acoustic properties of the different densities. Thickness is key.

Ya that's just regular insulation.. I saw somewhere that a foot of the fluffy pink stuff is equivalent to an inch or 2 of OC703. I loosely filled my ceiling joists with it, about a foot of it, and I noticed the difference in the acoustics but "soundproof" ? Hell no.. I suppose technically ANY mass will help soundproof a little. I can still hear tons of noise thru it and the floor, it's just a more muffled.

So you're saying it would help solve SOME acoustics in a bedroom, if I were to compress it into frame panels like they make for the OWENS 703? How much, do you think, would I need?

Ok, so it's regular insulation, I got that. Saying this is 6in. in thickness...I would need to make it a foot in thickness so that it could have tha same "effectiveness" as OC703?

-------------------------------------------------

Tha reason why I'm so interested in it is b/c its only about $4 here at the local hardware store. I just wanna know wut next project it could possibly be used one or maybe I could try building a "portable" vocal booth like real traps except out of this

Yeah, basically that's as effective as a 1/2" - 1" of OC703.

Hmmm sounds decent enough in my opinion...well tomorrow Ima go ahead & buy acouple of rolls. I'ma try to make a "portable vocal booth" out of it...

Their actually quite close down to near a hundred or so.
701, plain 4" (102mm) on wall 1.5 pcf (24 kg/m3) 0.73 1.29 1.22 1.06 1.00 0.97 1.15
703, plain 4" (102mm) on wall 3.0 pcf (48 kg/m3) 0.84 1.24 1.24 1.08 1.00 0.97 1.15
705, plain 4" (102mm) on wall 6.0 pcf (96 kg/m3) 0.75 1.19 1.17 1.05 0.97 0.98 1.10

None of them are considered a 'barrier' or intended to do the job of good old solid mass though.

So mixsit do you think it's a good idea if I try to build a portable vocal booth out of this thing

[mixsit]

It's more work since you have to contain fluffy', but if you're looking at portable gobos, with some isolation, you might be having at least one side solid any way? The slick thing with the more solid bats is you just cover or bag them and they stand or hang on their own.
Are you going for taming reflections and room ambience or hard isolation?

I want it to sound dry as possible...I know some may disagree with me but its my preference & I dont like arguing Something about a dry signal just sounds sooo good to me

[jhbrandt]

If dry is what you are looking for, you've got it. You can get the same absorption in less space with the regular thermal insul if you squish it into a smaller space. It will still have the same effect. - when you build your frames, staple the burlap or cover material in before you put in the insulation.. press the insulation in and cover the outside with plywood. You could use 1" X 2" or 1" X 3" frames.

But as far as blocking sound, like mixsit said, "None of them are considered a 'barrier' or intended to do the job of good old solid mass though. " - you will need something solid for the outside of your construction. Even 1/4" luan would help. 3/4" ply would be much better because of the mass...

Whatever your budget (and arms - it gets heavy) can handle.

When you make your portable booth, be sure that there is a way to seal the cracks. Rubber with clamps or something like that. Remember that a small crack can make a real nice sound partition or wall ineffective.

F. building a booth,if you don't go all out.
you have to have enough room to build a good size booth
if not your better off treating every wall in a closet
cuz the walls already have insulation .
building a small booth is money better spent on studio time,
acoustic treatment for a small space,or a portable booth
(se reflexion filter)ive built a booth, it sucked and i had to tear it down when i moved

1/2 minute worth of typing "Acoustics & Pro Audio Electronics" does not make you a Professional Acoustician.

Actually I ain't trying to build a whole/complete vocal booth just maybe something thats "portable"...I already pay for studio time...I just basically wanted to look into this & see if I could maybe try a project

[oblackmer]

Ha! yeah dude, im looking into making some all out collapsable studios someday... its true that its impractical and inneffective, but it is a cool project so good luck to you dude.

If you want a suggestion or two you should consider downloading Google sketch up since its free and a great way to develop and share ideas and I have a few that may help you make some badass modules.

[Mixteco]

Nevermind on this idea...I just recently purchased some 1inch studio foam

[oblackmer]

Eewwwwwwwwwwww!!!
