mshetler.design, 2 December 2010New project: Location: Dayton, OH, USA Budget: $2000 Purpose: Personal/Demo recording - possibly with full band (drums, guitar, bass, etc.) Music style: Rock, Indie Area…
mshetler.design, 2 December 2010Also forgot to mention the ceiling: - Currently it is a drop ceiling of "acoustic" panels - but my guess is they aren't very acoustic . . . There is hardwood floor on…
mshetler.design, 3 December 2010Thanks for the reply gullfo. I checked out the book on Amazon, as you say it may be a wise investment indeed. As for new joists - would you suggest they be connected to…
mshetler.design, 3 December 2010At first I was a little concerned with losing height by having to put the new ceiling joists on the new walls, but then I realized that I could put them between the…
mshetler.design, 3 December 2010So I just got off the phone with a sales rep at a local building specialty store. He suggested not going with the staggered stud, and rather using RC1 for the walls…
gullfo, 3 December 2010you need mass to isolate. hard contact means flanking. having a set of 110db drums below the bay's room means 75db or so in the baby's room... adding the proper amount…
mshetler.design, 3 December 2010gullfo, Thanks again for the reply. The basement room isn't actually directly under the new baby's room. We have a quad-level house, so in fact, the room above the…
mshetler.design, 6 December 2010is (2) 5/8'' without green glue okay? for budget reasons (remember I'm trying to strike a balance on effectiveness and cost), would (2) of 1/2'' be okay? Since the total…
mshetler.design, 6 December 2010gullfo - the current floor is solid concrete. Seems pretty "massive". Agree? I read somewhere else on the forum that two layers of 1/2" is no good. Agree? Will probably…
gullfo, 6 December 2010the upper floor is what i meant by existing floor... if it's concrete - great, if its wood joists and wood subfloor + finish floor, then i'd suggest adding the mass…
mshetler.design, 6 December 2010My mistake on the floor question. The existing first floor is: -Subfloor (as it is an older home, 1965, I believe these are 2 x 8 approx., laid diagonal to the walls)…
mshetler.design, 6 December 2010On the subject of insulation, is Roxul a better choice than fiberglass for the cavity spaces? I received a quote for $.46 sq/ft of Roxul from the same guy that was…
mshetler.design, 7 December 2010So, I'm having a little trouble figuring out how to do the new ceiling joists. I don't know what to do about the I beam. I know my HVAC rendering is pretty poor, but I…
mshetler.design, 7 December 2010Unfortunately I don't have access to sketchup right now to update the drawing, but I realized that if I shorten the double wall in the middle, and fill in the gap with…
gullfo, 7 December 2010http://www.kineticsnoise.com/arch/ceilings.aspx - using the isolation clips on the joists or adding the spring units and suspend the ceiling. both will only take about…

mshetler.design, 7 December 2010Glenn (sorry this is gonna be a long one), I am with you on the parallel trusses around the I beam, I guess my concern was if that span (~11 feet) of unsupported truss,…
gullfo, 7 December 2010the clips with the hat channel / furring strips (should be readily available in most building suppliers) will be better than the RC-2. use 2x 5/8" drywall on the…
mshetler.design, 7 December 2010Glenn, Understand on the heat and CO2. A whole sep. unit seems like it would completely eat up my $2000 budget. Unless I'm mistaken, I was under the impression that HVAC…
mshetler.design, 7 December 2010Glenn, I'm not sure I completely follow or if we're on the same page. If you look at the drawings I posted last night, I'm not trying to put a wall up on either side of…
mshetler.design, 8 December 2010Ruby script eh? If it is available online care to point me in the right direction? Understand about not coupling to the existing joists, but still don't understand about…
mshetler.design, 8 December 2010I'm glad our laundry room is in the basement, and that I'm somewhat lazy when it comes to laundry as I have to go down there just about every morning to get clothes…
mshetler.design, 8 December 2010Thinking on it a bit, I think I would still need to notch the new joists around the I beam support 2x4. I think about 1/2'' notch or so - 1/4'' for the difference in…
gullfo, 8 December 2010what i'd proposing is to put in the wood beam to allow you to span the gap in that space without coupling and encase the steel beam so it's also isolated from the room.…
mshetler.design, 8 December 2010I get what you're saying about the neoprene - I was actually thinking something similar. In all honesty I was thinking I would probably still build a soffit around the…
mshetler.design, 8 December 2010Quick question about beefing up the existing upper floor. The drywall I'm adding under the upper floor - does it need to be snug inbetween the existing joists? Reason I…
mshetler.design, 8 December 2010Glenn, See the attached pic - this is where I'm confused on your drawing. The wall in the red circle shouldn't be there - as there is no wall parrallel with the I beam.…
mshetler.design, 8 December 2010use 2x 5/8" drywall skip using different sizes. go with a 3rd layer if possible. yes, you can hang things on the walls recognizing any vibration and resonances which may…
mshetler.design, 9 December 2010Glenn, I think we're on the same page with the I beam now. Thanks for working through it with me! I think understand where the confusion was with that wall indent - I…
mshetler.design, 9 December 2010After looking a little closer at the numbers, looks like I may not be able to squeeze the two layers of 5/8'' on the ceiling and have the 1/4'' clearance below the…
gullfo, 9 December 2010beef up inside the upper existing floor as much as possible and use a single layer? or maybe ask the building inspector if you can be off by 1/4"? keep the 2x on the…
mshetler.design, 9 December 2010Quick question on windows. I'm planning on having a good sized window from the CR to LR. My father in law gave me the glass panels out of some patio doors a while ago.…
mshetler.design, 10 December 2010Glenn, John says 5/16'' is okay, and that the glass "must be on an angle" here: http://johnlsayers.com/Recmanual/Titles/Acoustics3.htm Just curious if you have had…
gullfo, 10 December 2010i usually recommend a minimum 3/8" (10mm) because anything less is simply less isolation. ultimately you want to get to the point where your basement floor becomes the…

mshetler.design, 10 December 2010Glenn, Understand on the thickness of the glass and the angles. I'll have to debate about the angles personally a bit more as it will most likely add a little bit of…
gullfo, 10 December 2010use the pink stuff. 3/4-1.2lb/ft3 (12-18kg/m3) density. the air is a critical component. using the denser stuff can end up coupling the walls and the lighter stuff has…
mshetler.design, 10 December 2010Glenn, Thanks, from what I understand the lower stuff is what I'm going to be battling most, so seems the lighter stuff is what to stick with as you suggest. Bouncing…
mshetler.design, 10 December 2010Along those lines (thicknesses), there will be a common wall - front of both CR and LR - that faces the rest of the basement. My plan was to do two layers 5/8'' on both…
mshetler.design, 13 December 2010Glenn, I understand about your triple leaf comment, and about the space in between the walls. However, the wall on the left of the CR isn't the exterior basement wall.…
mshetler.design, 13 December 2010Bouncing back to ceiling insulation for a second: I'm not going to have 3''-3.5'' (width of insulation) clearance between the new ceiling and the existing joists, or…
mshetler.design, 16 December 2010I think I have got most of my construction plans/concepts down! I was checking out my proposed rooms with the mode calc. on bobgolds.com and the way I see it (with all…
mshetler.design, 16 December 2010Understand on the bracket, saw that a few other places when researching construction of them. I was looking at the method for the smaller version, where you get 8…
mshetler.design, 20 December 2010After re-evaluating some of my construction costs, it looks like I have a little bit more left over to play around with treatment options. Here is where I am at: - (4)…
mshetler.design, 20 December 2010Thanks Glenn, makes sense. I took some more time to browse this site specifically for absorbtion construction methods - I had seen them on a few other places. Understand…
mshetler.design, 21 December 2010Glenn, understand on the plastic and will get plenty to use in other locations. I have two questions this morning: 1) In looking over John's plans some more I see he…

gullfo, 21 December 2010slot resonators can add a good amount of broadband absorption and preserve a lot of HF energy while being diffusive. they also take more work that just building up…
mshetler.design, 21 December 2010-Like the asthetics, yes -Willing to do the work, probably -Make the investment . . . unfortunately no. Glad to hear you say to start with the absorbers first, as that…
mshetler.design, 22 December 2010Option would be there I suppose, however I have a few concerns with that: 1) with the soffit there, sticking a good 6-8'' below my 7' ceiling, I feel like it would have…
mshetler.design, 23 December 2010Glenn, I think I know what you're saying, I'm pretty sure I'm going to switch the control room to the right side though - as after looking at it I think I should still…
mshetler.design, 4 January 2011Back to ventilation for a bit: I've been looking all over the site and in some other places trying to figure out the best course of action. Here's what I'm thinking. My…
gullfo, 4 January 2011build the silencer boxes and put a Fantech inline fan into the return so it draws out warm air and a passive supply box, or put one in both the supply and the return if…
mshetler.design, 4 January 2011Glenn, Thanks as always for holding my hand through this process!!! I've seen the fantech's listed a few times on the site. Any alternative brands, or is that the best…
mshetler.design, 4 January 2011Here's my calculation: My TOTAL studio space (both CR and LR) is 2240 cubic feet. I think I saw that I need 6 ACH (correct?). So, 2240 x 6 = 13440. So, 13440 / 60…
mshetler.design, 5 January 2011Glenn, Understand on the bafflebox/soffit - I was mostly trying to get away with only one fan (cost). Does the 6 ACH sound correct to you? And, if 112 CFM is my…
gullfo, 5 January 2011i think more like 8-10 ACH minimum. most fans make noise in a higher frequency which is readily absorbed in a large enough baffle box. besides CFM you need to consider…
mshetler.design, 6 January 2011Glenn, Noted on the fan/duct/baffle sizes. The price of two fans is really turning me off of that idea, but I think you are right about it being the better way to go. As…

mshetler.design, 6 January 2011At the risk of someone grabbing these out from under me . . . :roll: http://cgi.ebay.com/Fantech-FR-100-Inli ... 4ceed7c8d3 Any thoughts on buying USED fans? I could get…
mshetler.design, 6 January 2011Appreciate the comments Glenn and you probably have a good point. I like the idea of repurposing (the doors from REStore for example) - but in the end the stuff needs to…
mshetler.design, 6 January 2011Glenn, Thanks for the confirmation and advice. I understand what you are saying. I'm thinking, that: 1) With my second child on the way 2) Since the studio/music is…
mshetler.design, 12 January 2011I know it is only believed with pictures - but, I was able to get the framing for the LR complete over the weekend! Also decided to go ahead and seat my framed up…
mshetler.design, 13 January 2011Thanks as always Glenn! I'll proceed with: 1) Floor first, then treatments 2) Super chunks instead of spanning panels (any specifics for going this route -…
mshetler.design, 19 January 2011So, I finished the outer wall framing of the front double wall last night. After doing that, and trying to visualize my air baffles I quickly realized just how much they…
mshetler.design, 19 January 2011Thanks for the quick response Glenn. I will have to do some more thinking then to try and come up with a solution. I might have some more latitude on vent placement if I…
mshetler.design, 19 January 2011Brien, Thanks for stopping by my thread! Thanks also for the links and input. I was familiar with the second link, as that is where I was taking my 8 triangle cut…
mshetler.design, 18 March 2011Ah yes it has been quite some time . . . I would like to say that I have made a ton of progress, but while I have made some progress, it wouldn't count as a TON I think.…
mshetler.design, 25 July 2011So, no response on my question about the silencers below? Oh well . . . I wound up putting the drywall up first anway. I've completed hanging two layers of 5/8 in the…
mshetler.design, 26 July 2011Stuart, Thanks for the reply - you're right a picture is worth more than all the words. I don't have sketchup available at the moment, but did draw something up quickly.…
Soundman2020, 26 July 2011To be honest, I wouldn't put the silencer there at all! You'll be pretty much destroying the bass-trapping ability of your superchunk like that. You need the full width…
mshetler.design, 26 July 2011Stuart, Thanks again for the reply - I really do appreciate it. Looking back on it now, maybe I misunderstood Glenn when he said I could vent through the superchunk. He…
Soundman2020, 26 July 2011I'm sure he did! A duct in the corner is not going to affect the bass trapping much, but replacing most of the superchunk with a plywood box is certainly going to be an…
mshetler.design, 26 July 2011Stuart, Not sure I understand when you say "Get the proper ductliner" - what I meant was, I'm using rockwool, wrapped in plastic AS my duct liner. I thought I saw…
mshetler.design, 26 July 2011I haven't posted any pics in a while and since I've revived my thread a bit, here goes (the silencers that have been discussed as of late are in there, without the…

mshetler.design, 26 July 2011Thanks Stuart! Forgot I had this one too - photo doesn't really say much, but to me it means - "Finished hanging two layers of drywall on the ceiling of both the control…
mshetler.design, 26 July 2011Thanks for the link Stuart! If I read that correctly, I should be able to tear down all my framing, insulation, and drywall. Throw them away. Line all my walls, ceiling,…
mshetler.design, 27 July 2011Hi BriHar, I actually don't have any pics of the silencers with the lining. But, I haven't finished them yet so I may still be able to get a few (if I remember while…
BriHar, 27 July 2011Yes the idea being to emulate commercial ductboard (albeit the actual manufacturing procedure is probably completely different - but you never know) by applying an…
mshetler.design, 27 July 2011Hmm . . . the acoustic tiles part is specifically interesting to me since I have saved all the ones I tore down from my space. Glenn had suggested that these may come in…
Soundman2020, 27 July 2011A plastic cover on the fibers only inhibits movement a little bit, at the surface (unless you wrap it tight, which is not the idea!). Using any kind of liquid, such as…
mshetler.design, 27 July 2011Understand Stuart. All makes sense to me. Personally, I would think the plastic would do a better job of keep the particles in than paint would anyway. What I'd be…
mshetler.design, 29 July 2011After going over it a bit more I think I found a better spot for the HVAC silencers. The opposite corner in the live room is where they will go. I remembered why I…
mshetler.design, 1 August 2011Glenn, Thanks for weighing in. I have two of the silencers mostly lined as I described, with the rockwool covered in plastic. Two more without any lining yet. Are you…
Page 7
mshetler.design, 10 August 2011So, I'll probably go with the $29 per sheet of 48'' x 120''. The other local HVAC supply shops either didn't answer the phone or didn't carry it. Hopefully that's a…
Ro, 10 August 2011consider: you have a beefed-up double stud wall with both 2 layers of 5/8 GB. Then you make a gap in it. To make up for that leak you need to beef up again. Hanging a…
mshetler.design, 10 August 2011Hi Ro, Thanks for chiming in, let me see if I can digest this: So, you're saying that the 3/4 ply plus (1) layer of 5/8 GB equals approx. the mass of one (2) layer 5/8…
mshetler.design, 10 August 2011Beyond all my questions to Ro above, I thought maybe another illustration might help. Since the penetration into the wall is not inline with the opening in the silencer…
mshetler.design, 10 August 2011RJHollins, Thanks for stopping in. As for the baffles, that's not completely how they are built (or will be built). It was more just representational. The baffles…
Ro, 11 August 2011Jup, that's whay I'm saying :) yes sir. uhm... I'm saying the mass on the box (using 1xply, 3xgb) is equal but it's not a MAM system. There's only one side which has…
Ro, 11 August 2011I get what your saying. If you put another silencer on the other side of the wall your problems are solved. Again, the box will be an extension off the wall assembly. By…
mshetler.design, 11 August 2011Ro, Thanks for the message back. To clarify, there are no ducts in the room that are not inside the silencer. Since the silencer is going to butt up against the wall,…
mshetler.design, 11 August 2011After posting, I realized I still only had one leaf opposite of where the outside wall penetration was. So, I updated the illustration. My concern now would be that were…
mshetler.design, 11 August 2011Hi Stuart, Joking aside, I did not want to create one, but realisticly, if I drywall the studio facing side of the silencer, I would be creating this: Leaf One: (2)…
Ro, 12 August 2011The box is small enough not to make it a disturbing 3-leaf installation. Like I said, as the box becomes part of the wall, surround it with GB that equals your wall.…
mshetler.design, 12 August 2011Ro, I'm confused on how my pic shows the ducts as anything other than inside the wall . . . ? Let me see if I can try and explain: On the studio side of the wall…
mshetler.design, 12 August 2011Ro, Sorry for the confusion. Yeah the room on the right of picture is a recreational (non-studio) room in the basement. It is the air exchange room of the system…
