OK - So I originally built an isolation booth which was 6' x 8' and it worked out really well, that is, until word got out I had a studio and I began doing more and more work and drums became a common recorded instrument.
Now the neighbors are all pissed off and well, you know the story. So I will be tearing down the old booth, retain all of the acoustic material and start from scratch. The booth will share one common wall with the neighbor, and one wall going outside. So I will definitely not be using the common wall as a booth wall again...however, will a double wall design (and as such, double doors, and double panes of glass) give me a much better form of isolation totally unachievable with single wall construction?
I've been reading a lot on here, and understand the different ideas of acoustics and construction but one of the things I've literally been clueless about is ceilings. How do I create a ceiling to keep the sound in the booth?
I also have solid concrete floors, and exposed beams in the basement where this will be built.
Double Wall Vs. Single Walls

...you did? Then you missed this one: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=4063 ;) I suggest taking some time off to read this forum again, and pay attention to the stickies. There's good info here, also on ceilings etc. Check the construction forum part to SEE how it's done. Again, much good info here. If you have, after updating yourself, any specific questions.. feel free to ask them. We sure are eager to answer all your questions, but you've gotta do some homework first! have fun!I've been reading a lot on here
Yes - I did.
I couldn't find any relevant information pertaining to the difference between double and single wall construction, since I've seen it done both ways, and it appeared to me, from the information on the construction, both were equally successful in their own right (perhaps I missed intention of use). I also read the stickie, and I'm not asking specific information about my build regarding cost, anything to do with wiring, building codes or any other specifics other than if a single wall can achieve the same isolation characteristics as a double wall.
Perhaps I need to be more specific regarding ceilings, how are they being decoupled? It appears to me the drywall still needs to be physically attached even with those metal drywall brackets. So to me: it still looks like the sound will be transmitted through the ceiling even though my walls are not sharing any common walls. Does the added packed insulation provide the density needed to prevent the transmission, or is the majority of it provided by the drywall itself?
You probable wanted to back off the defense but didn't see it in the sticky. It's not uncommon. Folks read a few things and go out to get their license 'cause now they can build recording space. Hell, if that yahoo from Alabam-ah can do it, surely a well educated, where did you say you were from?, fella can slap one together!
The above statement reveals your lack of commitment to your research and underscores a lazy streak that you want the pros at this forum to supplement. This is only an observation not a character assessment ;) Brien I don't know why people hate me?I couldn't find any relevant information pertaining to the difference between double and single wall construction,
Subtle, yet right to the heart. I love it, in Hamilton. :D Geographically identified, AndreHell, if that yahoo from Alabam-ah can do it, surely a well educated, where did you say you were from?
*sigh* This isn't going to get us anywhere. I'm all for a push toward the right direction - but being vague isn't going to get me anywhere closer to solving my question. So as I mentioned, I couldn't find any relevant information pertaining to the sonic and isolation characteristics of double vs single walls. I've heard of and seen blue prints and examples of both working well, but again, I don't know if intent of use (mine would be to isolate drums from the neighbors and rest of the house) plays any part of it. You can't exactly use a fly swatter to take down a bull elephant. A phone call I made to a http://www.acousticalsurfaces.com also confirmed a single wall could be as effective as a double if properly constructed with mass loaded vinyl, and drywall hangers. So is this accurate information, or is this not? I have a lot of MLV from my current job, but again, I didn't realize I'd become popular to the rock crowd and be tracking drums so frequently - so I shared common walls with neighbors. This needs to be demo'd and a new booth put in it's place. So...again - does anyone have an answer, or if that's not possible at least a spot where I can find literature on the potential ramifications of either method?You probable wanted to back off the defense but didn't see it in the sticky.

Don't have any answer myself but for a start see:

The definition section is a hidden little treasure. Thanks a lot for that. So it seems to me, if I properly construct it, I could indeed use a single wall for tracking drums and I'd be able to keep it close to silent in my control room. Some one please correct me if I am misinterpreting this information, or if there's anything in particular that I may need to consider before finishing my final plans.

no, a single wall will not do more for isolation than a double wall.
drums = 100db+
"silent" control room = 15db
you'd need at least 85db of isolation. :shock:
IR-761 should be your first source for identifying tested wall constructs that will meet your isolation needs.
probably want to carefully consider how much isolation you really need.
Thank you very much. :) OK, so due to your suggestion, I will incorporate a double wall design, varying studs, dry wall channels, and the mass loaded vinyl as well, and insulate with lovely mineral fiber.no, a single wall will not do more for isolation than a double wall. drums = 100db+ "silent" control room = 15db you'd need at least 85db of isolation. :shock: IR-761 should be your first source for identifying tested wall constructs that will meet your isolation needs. probably want to carefully consider how much isolation you really need.
Mass loaded vinyl is waste of money in this application. The money would be better spent on extra layers of drywall and/or isolation clips like the RSIC. The most difficult part of sound isolation is the bass frequencies. As you study IR 761, bear that in mind.
Keep asking questions. The more you know, the less likely that you will mistakes.
Good luck!
Soundly,

Does your double wall design use the existing exterior wall as part of it besides the shared wall? What about the shared wall, is that poured concrete or block or wood framed or a little of each?The booth will share one common wall with the neighbor...I also have solid concrete floors, and exposed beams in the basement where this will be built.
No, the double wall design will not touch any of the existing walls. My idea for the double wall would be two wood framed walls packed with 2" rock wool, and I'll be using resilient channels as well. Do you have any other suggestions to make it more efficient? Thanks for the look!Does your double wall design use the existing exterior wall as part of it besides the shared wall?

I would want to build it as far away from an existing wall as space would allow.
Thanks! Space is certainly at a premium, so I am taking it to it's very edge.I would want to build it as far away from an existing wall as space would allow.
Resilient channel is not needed if you are building a double wall (& ceiling). The separate walls themselves will already be decoupled.
