Okie Dokie. It's time for more questions that need answers..

Hey guys and gals. I'm building a studio here in silvan south and need feedback on EVERYTHING!! The actual studio is 6 x 9 x 3.4 (see pic) with double brick walls. The design is pretty much there (Thanks to Mr. Sayers!) but I'm sure slight changes will happen. The place is set on 15 acres so there's no problem with disturbing neighbours, but maximum isolation between all the rooms is a must. This project is not only going to be a space for my band(s) to rehearse but also a business. We've got a budget of around $30,000 for the construction and plenty of help from all my carpenter/electrician mates! Now to the nitty gritty.. Floor - The floor is a 4 inch reinforced cement slab over a an additional 4 inch layer of crushed rock. Along with all the brick in the room the sound is already very bright and heavy in the high frequency range. I realy need to even it out. Should I install a floating floor? Is it worth it? What are the pros/cons? If not what would be the best way to go? Ceiling - As I mentioned, The ceiling is 3.4m. It's just plain old 16mm plasterboard. Above that, the structure of the actual roof (as you may have gussed) is a truss system. I have read a few posts on people who have floated a second ceiling below the existing one and caked the cavity in between with mineral/rock wool to increase isolation and absorbancy. Is this a good idea for someone in my situation, or should I put most of my insulation above the existing ceiling? Also, I should mention as you can see the bathroom already has a roof that extends over the bottom half of studio 2, all the way to the brick wall. (something I left out in the description for John.. Sorry John!) This roof is 2.75m high, leaving a gap of 650 mm to the "whole" room ceiling. In the case of putting up a floating ceilng, I was just going to extend out this roof over the whole studio. Is this a good idea? Will it compromise my sound? HELP ME!!!!!! Thats it for now dudes, but I'm sure I'll be back soon with more probing questions for all of you legends to answer! Untill then... Ta Ta.

the floor may allow flanking of sound between rooms - best bet is to take metal and rubber hammers and tap to see how well its transmitting. i'd just polish and stain the floor and add a small carpet here or there to tame it - with other treatments on the ceiling and walls the space should be nice and live - which could be made adjustable with reversible treatments.

if the existing structure can support it, i'd build each rooms walls up to the existing ceiling (remove the drywall between rooms and isolate top of wall from ceiling joists to reduce flanking path) and add 3 layers of drywall inside each room. additionally you could remove the existing drywall and put in RC2 on the ceiling joists and the add the new layers of drywall to that. add insulation in the ceiling to dampen the ceiling and use the space for HVAC equipment and ducts.

I'd use that space for bass trapping in the large room. put up a cloth wall with some slats and put hangers in there to effectively increase bass trapping.
