Flooring...any ideas to improve my limited options?

[psykostx]

Hola slutz and slutettes! My studio flooring is going to consist of 1/2" plywood subfloor, 3/4" plywood base, a layer of mass loaded vinyl, and then "pergo" snap together finish.

My question is, will this be sufficent to keep sounds from travelling through the floor and up mic stands, into furniture, etc ... not to concerned with STC because I live in the woods, but I am trying to reduce the resonant frequencies of the construction to a low enough vibration where my mics won't pick up through the stands, and my monitors and subwoofer won't play back through the floor to my feet and furniture. Do you guys think this would be sufficient, and does anyone have any suggestions?

Money isn't really the issue, it's just that the subfloor and base are already installed, ideally I'd like to tear them up and install Roxul between the joists (which has been done in the walls, along with the mass loaded vinyl, which seriously kicks ass by the way, the room reverberates like a dream for the money I spent, no flutter, and no sheetrock "" sound). What you guys think? Is it worth it to rip up the subfloor (serious PITA) or should I just go ahead? There will be drums and loud amplifiers, as well as floor standing and stand mounted monitors in the room. Control room coming soon on a different floor (e)

I don't think the floor design mentioned will provide a solution you desire.
Sound just loves traveling thru solids.

Not sure there is enough info to make an educated guess.

What is your concern? Vibrations to the mic stands? There are plenty of "shock mounts" available to purchase. What furniture? In the same room or a different room?
Either way, one wouldn't need to put a quarter in it.

Why do you have two subfloor layers?

Can you blow in insulation from the ceiling below?

There is good reason no one has responded.

What is the good reason noone has responded? Not trying to be snooty...

There are two subfloor layers because it was originally an attic that the previous owner had started converting into a master bedroom but subsequently sold the house to myself.

I raised the roofing ties and now I have a good 15 ft ceiling with two different slopes.

My concern is isolating instruments from one another and damping the floor to a frequency that is inaudible. It's already a pretty solid floor, and I will be using a drum rug as well, so I'm looking for the closest thing to a floating floor that is possible with standard household construction. The walls and ceiling have all been treated with MLV and it works like a charm, the only problem I'm having is with the floor, because I can't tear it up without a lot of extra work in order to suspend the vinyl across the joists.

I'm not interested in quick fixes like shock mounts etc ... I really want the instruments to sound where they stand. I don't want the kick drum to be omniscent, I want it to sound like a point source. I realize there are many other factors involved, but I was under the impression that the floor is an important one. I've built many studios before and this time I actually have the cash to do it as correctly as possible in a residential situation (but not the time unfortunately). So is tearing up the floor my only viable solution, or would placing the vinyl on top of the subfloor still be effective? There is already blown in insulation inside I believe, but I would prefer Roxul AFB to catch some of the lows and really boost the effectiveness of the construction... not to mention keep the consistency going with the rest of the project. Thanks for your replies ... any suggestions? Any info I left out, please let me know.
