How's this?

Hi there! I hope you wouldn't mind having a quick look at this and see if anything seems totally off... It's important to mention that space is a huge priority and that's why the rooms are square - I know it's bad but I hope to make the recording area sound ok with proper treatment afterwards. The walls are 50 x 100 mm wood framing and two layers of drywall, with mineral wool facing outwards in the recording area and inwards on the two outer walls. Floor in the recording area will be floated on neoprene pads, joists (100 x 50mm) 2 X 16 mm plywwod and some nice finishing flooring. Glass will be 10mm and 8mm. every wall be spaced 100 mm from nearest adjacent wall. Does this look OK to you or have I overlooked anything obvious and stupid :D Oh - and here's a question: what lumber size is the most common for framing - you guys don't seem to be using 2 X 4's for framing? Here's the sketchup file (too big to attach) http://www.tonekontrol.dk/video/UMlaut_finalsketch_reversedoors.skp

No one...guess we're allright then :D

Dont know if I can be much help, but as far as framing, I am using 2X6's for the exterior walls. This will give me the room/depth I need for the R-19 code required insulation. As far as interior walls, I will be using 2x4 framing except for on the ceilings (the ceilings within the ceiling) where I will have 2 layers of Drywall attached. Due to the weight, I am going with 2X6's. Also as was pointed out in I think one of my posts by one of the masters on here,,,,I am spacing my interior walls 24" OC instead of 16 OC, so the "slop" between the 24" studs helps with sound isolation. Exterior 2X6 walls will still be 16 OC though as well as all ceilings. And I totally understand the room issue, and the want to have square rooms. I started the same way and was determined to keep things square (again for the space and ease of conversion later if need be) but since I got started on here, I have made the needed changes so the rooms arent square. And believe me, I tried every angle (no pun intended) as far as splaying walls inward, outward and even looked into making them slant in or out vertically. I wanted every last inch of space. Bottom line, you might want to conceed as well, and just splay wherever you can as you build. It appears thats the way to go and it will pay off in the end. :wink: Or just angle 2 somehow so there are no parallel walls. There,,,thats just my 2 cents,,,, and actually my first post as a response to a question. :D I am usually the one asking them, not the one trying to answer them. :lol: Good Luck AJ

Lasso, Here are 2 pictures below of the studio design from my first post on here to todays design (after all the coaching and help). Check out the differences. I think in your situation, you could go with splayed or angled walls on the wall dividing the control room with the tracking room as I did. That might be a start. :wink: Check out the changes made since I started on here. (and I am sure its still not right. lol) AJ

Sorry to bump this, but I'm starting building this weekend. Would anyone of the regulars mind having a quick look at this? Please tell me if anything needs clarification? I've only been able to get 1 cm thick neoprene...question remains: should I just go by theese or in fact use two pieces of neoprene (2 cm) instead of one for the floating floor?

i think you should make sure your rooms are not square - extend or shrink them. see if you can get them close to one of a number of optimum room ratios and then do a good job treatign the rooms to get an even a response as you can without making the rooms too dead. put up treatments in all corners including wall-ceiling corners. clouds and carpets staggered to reduce floor ceiling reflections. a copy of Rod's book on studio construction will go a long way to assisting in getting the isolation working as expected. why are you floating the live room?

You're saying that you don't want to build the walls on angles to save floor space. Then your going to go back and treat the room.. with what? Anything you do is going to eat up space. The point of angling the walls is so you need less treatment later.

maybe this works - blocking off a few of the windows still leaves 1 window in each space. not sure if the items under each window are radiators. if so, put something into the 2nd CR bass trap area to conduct the heat from the (blocked) radiator into the live room. heavy drapes over the internal windows to cut high-freq reflections. may need more than that though.

@ gullfo. THanks for taking the time and effort! The primary reason not to angle is simply a matter of space. I'm mostly doing commercial stuff, podcasts and so forth more than I do music, so saving room is more important than stellar acoustics at this point. I'm floating because we are at 1. floor and nextto a railway. Anyway...we build the floating floor this weekend and it turned out great. Next up is the rest of the framing:)
