Help!!!

Yes I know not a very good topic

We're doing the shed up and need to 1st sound proof it as the coupple next door have just had their first baby. Does soundproof Gyprock really work? We're building a room within a room and are thinking of Frame-Insulation_gyprock-? the "?" was originally carpet but I was told to stay away....help?

Also we were thinking about putting foam on the roof, if we do this what is best to go on the floor?

I'll be using this as a recording and tracking room, and the cealings arn't high so I need to make it as dead as possibal?

Thanks for your help.

Post back for clarification, When you say "soundproof" everyone and their brother is going to start posting all sorts of stuff about how that is impossible etc. To truly soundproof, you need to have isolation, really basically, two layers, seperated. That is a "floating" floor/wall system. If you have the sound in your room running into a wall that is connected mechanically to the outside directly (that is sound->wallboard->studs->wallboard or outside facing of the shed) a good portion of the sound will transfer throguh these connections to the outside (like beating on one side of a drum transfers to the head on the other side, but not on purpose).

OK so now that that is clear, what you probably mean is "as close to soundproofed as can be". Your best bet is to add tons of mass. The soundproofing sheetrock you are talking baout will help, but it doesn't "work". It will not be a solution, becasue andy gaps will transfer sound outside, and the surface to surface transfer stuff above will as well. You probabaly can get something done about as well, cheaper with normal sheetrock, dounled up. Peopel with extensive knowledge can give you tons of specific solutions, but if you were to caulk all seams and gaps, fille hte framing with 703 or similiar absorptive insulations to absorb sound especially bass frequencies, and put two layers of sheetrock ont he inward facing walls you would have a good start. Your weak psots will be outlets, windows, doors where you can't put a solid unbroken mass in front. Try to think of filllign this stuff with as much mass as you can, and make sure materials you choose are fire resitant.

Also, since you post int he guitar forum alot, i am going to assume that amps will be your big sound generation. If you have drums and bass and guitar, your big issues are going to be with the low frequency stuff that will want to go right through the walls. If you are practicing with a band, you are pretty much screwed, do the best you can to add the mass you need to quiet it down, but the low frequency stuff is going to go through wether you like it or not.

if you are recording, consider builting an isolation cabinet, where you can get that islolation I posted above on a smaller scale. Build a box, with a speaker inside (don;t try to make room for a whole amp, all you need is the speaker and it will save you tons of space), and access for a mic and stand and cabling. Then put that inside another box, with as much seperation as possible, maybe some sort of heavy rubber feet or something that will not transfer the sound vibration as much, and then fill the gaps between the two with 703 and other heavy mas sound absorption. Put that box in your treated shed and you might get some real isolation.

Whoa there buddy, you are highly oversimplifying this concept. And by the way, its NOT just walls and floor that need to be "seperated", which right there does NOT specificly tell the whole story. Each LEAF of a standard residential wall is "seperated" by an airgap. This is called a two leaf system. However, to increase the TRANSMISSION LOSS of the assembly, one leaf needs to be "decoupled" from the other, which can be accomplished in a variety of ways. However, before you go assumiming things, there are MANY MANY other factors to take into consideration. This is where INFORMATION about the existing structure comes in. Whats the sense in building a "decoupled" inner leaf assembly, and or floor, if the existing floor is a wood framed assembly. It simply acts as a drum head and structurally transmitts vibration directly to the exterior leaf. Same with the cieling/roof. If terms like "decouple", leaf, etc are unfamiliar to you, I suggest you do some reading.

But for the moment, at least untill dwarf can tell us EXACTLY what the existing CONSTRUCTION of all the assemblies(floor, walls, ceiling/roof, doors, windows etc)are like, and distance to neighbors, here is a diagram to illustrate the concept of "leafs" and decoupling. However, this is very basic, and doesn't even begin to cover the concepts of decoupling a floor, or cieling, and doors. Once we know the details of what exists, maybe we can offer some REAL solutions.

Thanks guys dorry I havn't been around work and school have been hounding me, I'll try to get the specs tomorrow we've put up 2 frames now, but yeah close to "soundproffed" is ok.
