Warehouse studio, the return!

The return of the warehouse studio... I'm constructing a studio in a warehouse, there are many details I could throw at you, however, I figure for now I'll just keep it simple. This was an on and off project for a while, but it has finally been decided that the construction will take place, framing of the control room, entrance way and live room starts shortly. I am however having a minor problem designing the acoustic treatment for the Live Room. The control room design is done including acoustic treatment, but I've noticed this forum seems to revolve primarily around the construction, design, and treatment of the control room. I can find very little on design concepts of a live room.... So I was wondering if anyone would care to help design the acoustic treatment of this particular live room... It will be primarily drum tracking as well as a live room for guitars (if they're looking for that "bigger" guitar sound). I just can't decide what angles to use, what absorption vs diffusion to use. The Floor will be completely reflective and the ceiling both angled and completely absorbent. The eastern wall has a window built in that is shown in the picture, the picture is drawn to scale, this is an older drawing, but the dimensions of the actual room are the same in the newer version, it's just easier to see everything in this drawing. Dimensions of the room are 15.2 ft x 14.4 ft x 8 ft high, any input is greatly appreciated. Primarily input involving acoustic treatment of the live room. Thank you.

I don't know if I can help, as I'm pretty much of a newbie here myself, but I'm curious: Is that a standard stud wall around your control room, with a single layer of drywall on each side? If so, then I guess isolation just is not an issue for you? I guess if you are building in a warehouse, that might be the case. Also, if that is the case (stud frame with drywall on each side), then I see a three-leaf problem between your control room and your live room. Maybe even four-leaf, depending on what the wall around the live room is made of. Could you provide more details on how those walls are built?

Right, I can see where you would see problems in that, however, only details relevent to the question were provided, this is an older drawing of the design, there is actually more to the studio below what is shown, but besides that, the walls are actually 2 layers of drywall, 1 layer of chip board, on the outer wall side. The inside wall is rockwool, followed by cloth, unless treatment framing is shown, in which case different techniques will be implemented. However the order is as follows started from the rightmost wall of the control room, (rockwool inside of standard framing, 2 layers wallboard, 1 layer chipboard {all one leaf}, secondary framing {fake frame} to support R30 insulation, then an air space of 2 feet, followed by the revers for the live room (so R30 inside of non-weight bearing framing, 1 layer of chipboard, 2 layers drywall, weight bearing framing filled with rockwool 4")) This acts as 2 layers between each room with a 2 foot air gap for extra sound spring. Not Shown there is an outerwall that does surround the entire building, this is a single leaf wall with insulation on the innermost side, this acts as a barier between the outside world and the studio. Slats will be used to reflect highs and mids inside the rooms where desired. However the question that is holding me up on further design is more what to do for acoustic treatment in the live room, I have a couple ideas, I'll post them as soon as I put them together. Thanks for the input :) EDIT These are a couple of ideas, but i can't do what i would prefer (ideal) for treatment because of the door and window. Key: Red = Slats (reflective with insulation behind) Blue = Absorbant (cloth over insulations pannels) Yellow = bevel, soffit mount

Aloha Cap'n, Hey, long time no see. Speaking of which, is it just me or are your images missing? Aloha 8)

Dimensions of the room are 15.2 ft x 14.4 ft x 8 ft high, any input is greatly appreciated.

I think those dimensions are way too small to get any sort of pleasing "room" sound. Could definitely work as a treated dead room.

No it's not just you Ken - I can't see the images either! :wink: Aloha btw! Regards, Lou. 8)
