RJHollins, 11 September 2010What a wonderful resouce this site is !! I'm a new member, and an opportunity has arrived to build a new Control Room in the basement. I had worked some 25+ years as a…
Soundman2020, 11 September 2010Hi RJ, and welcome! Your basic plan looks reasonable, but there are a couple of things that you could do to improve it. First, your speaker/mix-position/room geometry…
RJHollins, 11 September 2010Hello Soundman2020, Thank-you very much for looking at this! This is my preliminary layout, and as you observed, there are issues and limitations to deal with. First you…
RJHollins, 12 September 2010As mentioned ... there are always issues to resolve :| I've enclosed 2 photos of the 'center load bearing beam'. This is the main dividing point between the CR wall and…
RJHollins, 13 September 2010I hear yah :) heck ... I can't even settle on WHICH direction I should have the monitors facing !! :shock: I do want the monitors firing into the longer length. The…
RJHollins, 13 September 2010To get the pump hole 'out of the way' I'd have to move the wall in about 2' to also get away from the upper-level garage drain pipe [drains into the sump pump]. We are…
Soundman2020, 13 September 2010OK, sounds right to me! As long as you did the math and got things roughly right, that's fine. It's probably just an optical illusion that makes the char look further…
RJHollins, 13 September 2010Hi Soundman 2020, Well, you covered alot of things ... but trying to use the 'quote' feature was getting to be a mess for me. Let me respond to a few points you made to…
Soundman2020, 14 September 2010Soffit mounting is probably the single most important thing you can do in your room. The benefits are multiple, and very worthwhile. IF you are going to be doing…
RJHollins, 14 September 2010Oh my ... I wondered what brought that idea on ! :shock: And my SINCERE apologies ! The 'window' idea came about due to concerns I had if one of my elderly parents…
Soundman2020, 15 September 2010Aaaah! OK, I get it. That makes sense. So just checking, but that space that I thought was your vocal booth, is actually just empty space, with nothing much in it? If…
RJHollins, 15 September 2010That 'space' is going to have to be a storage/workbench area. The planned 'new' wall really marks the furthest line I can go. It's aligned with a clear floor joist…
Soundman2020, 16 September 2010It doesn't based on lumbar, but rather in relation to how much isolation you need. The air gap (distance between the hard surfaces within the wall) is part of the…
RJHollins, 16 September 2010Thank-you Soundman2020 for the explanation and clarification on the walls and gaps! I will definitely try to implement. If I may ... I do have a question as to dealing…
Soundman2020, 16 September 2010Not necessarily! Try something like this: http://www.digistar.cl/studios/2010%20U ... 5d-S04.skp The room is a little smaller (15'8", 11'7", 6'8"), but the ratio is…
Soundman2020, 16 September 2010Yeah, I saw that in the photos you already posted, and I took that into account with the ceiling design. The drywall is about an inch clear of the existing joists. You…
RJHollins, 16 September 2010Hi Stuart, OK .. just got back! In the world of CAD ... everything can be made with perfect corners and parallel surfaces. However, this be no CAD reality. I started to…
RJHollins, 17 September 2010OK ... I probably made a mess with the SketchUP attempt at new measurements. In fact ... In know I DID. I now realize that the variations in HEIGHTS are due to the SLOPE…

RJHollins, 19 September 2010Was able to do some very unscientific NOISE tests. [C-weighted]. The source noise was my shop vac which generates an SP 90dB @ 1ft in the basement [just below the…
Soundman2020, 19 September 2010Well, that at least gives you an idea, and leads you to a conclusion: You need way more isolation than you have! But it may be a bit worse than you think: Your shop vac…
RJHollins, 20 September 2010Well ... a SNAG in the plan to get noise level measurements :roll: Just found out this morning that Mom has come down with a case of the shingles. She is on the couch…
RJHollins, 23 September 2010Alrighty then ... finally able to get some noise measurements. Here's what we got. In the basement, I set up monitors for the test. For the source music, I used the…
Soundman2020, 24 September 2010Well, you can draw some rough conclusions, then, based on those rough numbers. It seems like "'barely perceptible" must have been somewhere in the region of 40 dB, which…
RJHollins, 24 September 2010Ahhh Stuart ..... THANK-YOU. This has been some of the best news I've received in quite some time. :) All the issues/concerns of importants you have nailed. From all the…

RJHollins, 27 September 2010Thank-you Andre. The words you speak seem to ring true for so many things in life. With all the activities today ... I managed to assemble and load 5 more panels.…
RJHollins, 27 September 2010Talking with one of my 'resident fabric experts', she was wondering if the burlap fabric could be velcro'd on the back of the aluminum frames? That way, the 'covers'…
xSpace, 27 September 2010"Am I stuck using only burlap?? If NOT ... what is the name of other fabrics I could use?" It isn't the material so much as it is the process. The process uses "dye" not…
RJHollins, 27 September 2010OK ... the 'muslin' looks like a nicer material [I need to hit JoAnn's to get a better look]. I'm searching around town to see if anyone does the dye-sub work. I'm also…
RJHollins, 28 September 2010As I eagerly await hearing back from Stuart ... I've been keeping busy reading through all those PDF files that were provided ... and ... calling around regarding…

RJHollins, 30 September 2010Thanks again Glenn, I'm looking at the diagram in Rod's book [p. 67]. Makes sense, and I have a better understanding on how to do this. Rod doesn't seem to mention the…
Soundman2020, 30 September 2010Still here! Just got lots on my plate right now. But Glenn and Andre and Brien are on your thread, so you don't need me too much! You WILL still need to ventilate that…
Soundman2020, 30 September 2010A comment that isn't really pertinent to this thread, but I just noticed some interesting stuff on IR-802, Andre. Figure 7 and figures 18, 20, 23, 24, 25 and 30 ... :)…

RJHollins, 4 October 2010Was not able to get the SU file posted here :( So I just labeled the image for now. Here's a question ... if we $ DONATE $, are any other options available [like larger…
Soundman2020, 4 October 2010On your first set of drawings I'm curious as to why you decided to go with hat channel and RSIC clips, instead of with interleaving new joists between the old joists, as…
RJHollins, 4 October 2010The advice, guidance, and KINDNESS has been priceless ! :mrgreen: I made my '1st install' donation 8) [still putting my build budget together, and this forum will be…
gullfo, 4 October 2010in my design, the new inner walls are isolation walls. you already have existing walls on 2 sides and only need to add interior walls to hide the backs of the new walls…
RJHollins, 4 October 2010Hi Glenn, Say ... I think I need to post a SketchUP file that will better identify the house layout. Due to the file size restriction, I think some pertinent concerns…

RJHollins, 13 October 2010Thanks Glenn for looking over the room size. I really did not want to mess with your design, but the isolation figures of the dual wall was something I wanted to have…

Soundman2020, 25 October 2010Sounds like a good idea to me! Yup. You will be sealing all of that with caulk. The "overkill" method (and thus highly recommended here...) is to run three beads of…
