stosostu, 31 July 2011Continuing on from my previous threads and various studio plans that came to nothing, I have finally started construction. The basic building is a 12 metre by 8 metre…
stosostu, 6 August 2011The only building I'm doing at this stage is the outer shell, putting a layer of Soundscreen and a layer of gyprock on the walls and ceiling and sealing it to form the…
Soundman2020, 6 August 2011Actually, it isn't. Not even close. The left side wall is at an angle of roughly 120 degrees to the front wall, while the right one is at an angle of only about 105.…
stosostu, 6 August 2011Thanks for the replies Stuart. Regarding symetry, I will have another look at the layout and see if I can achieve a symetrical design. Re the walls. The outer skin is…
stosostu, 9 August 2011Regarding air space, the light blue in the floor plan is the air space and there are three large areas around the control room, but I guess you are saying that the space…
stosostu, 11 August 2011Thanks for your replies Lil, your studio and the way you built it have been an inspiration to me. The reason for the orientation of the control room is that I really…
Soundman2020, 11 August 2011The room is too small for diffusers to be advisable. That information is available in numerous places all over this forum, if you search for it! :) The question is not…
stosostu, 11 August 2011Thanks for your reply, Stuart. How can I do that before the studio is built? BTW I do have a sound level meter and sound sources. With regard to isolation from the…
Soundman2020, 12 August 2011It is??? Really? Wow! that's going to be news to a lot of the professional designers who hang out here! I bet they have no idea that most of their designs are "not…
Soundman2020, 12 August 2011Great! Then set up your full-range system to play sine sweeps, pink noise and music that covers the full spectrum, with emphasis on the low end. Set it up to play…
stosostu, 13 August 2011Stuart, thanks for a great and detailed reply, I feel that I am now getting somewhere. With regard to the initial measurements, I assume (dangerous, I know) that I…
stosostu, 4 September 2011I have now got a copy of Rod Gervais book and have started to read it, but I'm still struggling to get a grasp on the layout. I am stuck with the actual building, which…
stosostu, 27 September 2011Things have been quiet around here for a while, I've been busy with other things and vigorously studying the two texts above. I am now wondering if the following is…
Soundman2020, 27 September 2011You are missing insulation in the air space between your two inner leaves! Very important. If you leave that out, it will cost you many dB of isolation. It is still…

Soundman2020, 28 September 2011I don't see any conflict between what John said and what I said: John is correct: The metal is thin, and the air gap between it and the next leaf is not sealed,…
Soundman2020, 28 September 2011To understand what I'm trying to say about how an air gap is still a spring even if it is not sealed, take a look at this thread:…
stosostu, 28 September 2011Stuart, thanks again for all the time you are taking to explain this to me. My understanding of a standard two leaf double wall, ignoring the framing is, layers of…
Soundman2020, 29 September 2011Yes and no. Your diagram is correct: your description is not. You seem to be confusing the insulation and the air space: they are one and the same. Insulation is mostly…
Soundman2020, 29 September 2011Yup! That's it! What you show will get you maximum isolation. Filling the entire cavity is, indeed, the way to get the most possible. However, Rod once pointed out that…
stosostu, 30 September 2011Thanks, Stuart. As you say, the insulation on the inside of the inner wall is for treatment, as per John's 'inside out wall', it will be covered with cloth then some…
stosostu, 1 October 2011Unfortunately, Stuart, they don't appear to be available in Oz. What I'm thinking of doing is making a lightweight wooden frame, since it only has to support the weight…
stosostu, 27 October 2011I have been talking to my suppliers of Soundscreen and gyprock about the problem of fastening the Soundscreen and they have suggested just gluing it on with Liquid…
stosostu, 28 October 2011Thanks Stuart, and thanks for guiding me through this minefield. One more question: Green Glue. If I put Green Glue between the gyprock sheets that will cost me an…
Soundman2020, 28 October 2011I reckon the real question is "How much isolation do you need?"! And secondary "Where do you need it?" (what part of the audio spectrum). GG won't do much at all for…
stosostu, 28 October 2011My plan was to measure how much isolation I have with just the first wall, then to work out how much more I need to achieve from the second wall, insulation, air gap,…
Soundman2020, 28 October 2011Ahhh! OK, now I get it. I thought you were planning to figure what GG on one wall was giving you and use that to predict what adding another wall would do. If it's just…
stosostu, 29 October 2011I haven't done any 'scientific tests' as yet, as I still have a few sheets of gyprock to install on the ceiling. I will post the results as soon as I get them. BTW…
stosostu, 9 July 2012Haven't been on here for a long while but the studio is still proceeding, slower than I'd like but proceeding. The answer I found for fastening the insulation to a sheet…
Soundman2020, 9 July 201210mm drywall? That's too thin. You should use 16mm only, and it should be fire-rated drywall, for maximum mass. The problem with thin drywall (10mm and 13mm) is that it…
