I'm constructing a small studio on the main level of a storefront building, 8 feet from a local street (low traffic), in Minneapolis. My floors are constructed of (subfloor), 5/8 rock, green glue, 5/8 plywood (not yet finished with hardwood flooring). I am about to frame in the new walls (room within the room) using the staggered stud on a single 2x6" plate method. I am wondering whether or not to attempt to 'float' my wall plates on neoprene rubber or not. Will this help decouple my walls from my floor, or will it just waste money?
Rubber under my wall plates?

Image is too wide... It's over 2000 pixels. It needs to be reduced down according to this announcement.
oops, sorry. won't do it again.
thanks,

Still too big... It currently measures 1008 pixels wide. The width needs to be <700 or <750 or <800 pixels (it's been said all three ways).
ok, I omitted the floor plan because it's not very relavent to my question.
It's a good question, and there's actually a thread that's pretty active on the same subject here http://www.johnlsayers.com/phpBB2/viewtopic.php?t=839 you may find some answers there. It's definitely not a waste of money, just make sure you get the right stuff or you WILL waste your money. :)
Why are you doing "staggered stud" instead of separate wall frames?
There are several problem with using continuous rubber as an elastomer under your wall frames. In order for the rubber to act as a spring, it will need to be allowed to compress/deflect somewhat, preferably around 10-15% to give you elastomer properties without overloading it (thus shortening its lifespan) and without underloading it (thus not acting as a spring). If you float the walls on pucks, you have large air gaps you'll have to fill with something resilient.
Then, you still have your floor that will act as a flanking path for structure borne transmission. :roll:
Honestly, you haven't yet posted enough detail about your intentions. You haven't yet told us how many sheets of drywall you intend to use on your staggered stud wall -- you've only told us your method of framing. You're concerned about decoupling (which is good) but you haven't given us enough of the variables in the equation to even know if your proposed decoupling method is sufficient for the amount of mass you'll be using. It could be that the amount of mass you intend to use is way too small, such that decoupling won't be your weakest link (the lack of mass would be).
What about that ceiling? What's overhead?
Review the "Before You Post" announcement thoroughly and present all the information that is requested in that announcement. Don't skimp on the details -- nobody ever gets lectured on providing too much information. :)
Extreme anal detail needed. Imagine you have to describe your building in such detail that it has to be recreated by someone else. That's what we're talkin' about.
