best sound insulating under sheetrock
Getting ready to sheetrock a garage for a music room. My main concern
is sound absorbtion to not bother neighbors. I was planning on fiberglass insulation under the sheetrock, between the 2x4s. Is there something better that I can use in this space, not too expensive? I'm guessing the fiberglass would help quite a bit. |

The fiberglass will help keep the interior temperature more habitable, but it won't do much for blocking sound. For that you need *mass*. Concrete blocks filled with concrete (or sand) provides some mass and is "not too expensive" (depending on your definition) |

I built a dedicated listening room/studio after much reading. The first thing you need to do is get "resilient channell" to hang your sheetrock on, do not nail them into the studs, because no matter how much "dense" filler you put in, the sound vibrates through the wall studs. Next, if you can afford it, put 2 layers of sheetrock up, one 5/8" and one layer of 1/2". there are a lot of expensive pads on the market that work quite well if you have the money, but I found It was unnecessary. I frequently play at 100+ decibels and you can barely hear it a few few from the wall outside. good luck jb |

That's Density - Isolation - Density, which is what you go on about. The Mass, you think is a "misnomer" is your two sheets of dry wall. The isolation is the channel. There is also a sheet rock product on the market that comes in different width sandwiches that are already isolated. Haven't used it. but it looks lie a good theoretical approach.

I used lined R19 between the studs and then used a vinyl barrier between the drywall and the fiberglass. I got the barrier from AcousticsFirst.com. They're pretty good at what they do. Doc Weaver |

Is there something better that I can use in this space, not too expensive? I'm guessing the fiberglass would help quite a bit. Mass is good. The more massive, the harder to move. Stiffness is good. The stiffer, the harder to move Isolation is good. If things aren't in contact, they can't move each other. So what you need is effectively a room within a room, with the inner room isolated as far as possible from the outer garage walls. I.e., don't fix studs to the walls and nail sheetrock on them. If the garage has a really solid concrete foundation, you can stand the inner room on that. The big problems will be any windows and particularly the door. An up-and-over or roller door may as well be left open for all the good it will do, so if this is a serious project, you need to brick up that opening and treat it as just another wall. Fibreglass and fillers are just final tweaks. Personally I wouldn't use fibreglass, because it tends to get loose and eventually cause skin irritation. d -- Pearce Consulting http://www.pearce.uk.com |

There's nothing better than fiberglass that I know of. The suggestion to alternate mass and an air space is correct, and resilient channel is good too. Also look into Green Glue he http://www.greengluecompany.com/ There's a lot of good advice on that site, so spend some time there to read up on the various construction methods they tested and reported on.

Instead of saying mass is "not" the issue, I meant to say "mass is not the ONLY" issue. Isolation, and preventing the vibrations from transfering through the materials is the key concept. essentially the whole room needs to be working together to prevent this. and once you have the "sound proofing" issues resolved, you may want to look at the accoustic properties within the room itself as regards "nulls/voids, flutter echo" and generally how the shape of the room contributes to the overall sonic quality" Good Luck jb |

"Mass" is not the real issue, it is a common misnomer. "Mass" is the correct name for what he was talking about. Whether he was right or wrong, it is not a misnomer. -- Posted via a free Usenet account from http://www.teranews.com |

I used a product called "loaded vinyl" sandwiched between two (different thicknesses) or sheet rock. It worked very well for me. This stuff used to be called leaded vinyl, and a friend of mine thinks that they probably changed the name for environmental reasons and that it is "loaded with lead". Auralex sells it under the name Sheetblock, and it is available elsewhere as well. It is about a pound of limp mass per square foot, is about 1/4" thick, and is not cheap. But as I said, it did work well for me. |

We talked about a multilayered approach with said material, plaster plates and tar plates. The idea was to have mass/weight and using materials with different vibration dampening capabilities. Still haven't finished evaluating, though. I spotted these readymade boxed yesterday: http://www.whisperroom.com/ Smalles useful one is 3½x5 ft: $3450, ouch! And I want it larger... Dampening isn't enough, especially at lower frequencies, but it's interesting how much the do dampen, using just coated MDF of sorts.

Just build a double sheetrocked wall with no physical connection between the
two. You can throw some fiberglass insulation between the two if you want. It's amazing what a space of dead air will do. Just picture a Thermos bottle. "Mogens V." wrote in message ...
