  • FriFlo, 24 September 2012Hi guys! let me start by saying, how great I already find this forum! Lots of useful information and everybody seems to be very helpful and kind. :D In this thread I…
  • FriFlo, 24 September 2012Ok, round 2: I will go through the details, as I planned them: 1) The separation wall: The first wall was already built 4 years ago. I remember selecting the room…
  • FriFlo, 24 September 20122) Soffit Mount Positioning (this is actually how I found this site - took me an hour to find out how the english term is ... :? ) What is it? This is probably the most…
  • FriFlo, 25 September 2012Thanks for the reply! Hmm, is this really VERY important? I already started on that wall (as I told, I regret that I found this forum a little to late ...). So I would…
  • FriFlo, 25 September 2012So, if I understand you correctly: You would agree, that building the second wall on the other side would be an over-kill of effort in my case and leaving the plan as it…
  • BriHar, 25 September 2012Before getting into some of the other details, let's look at your isolation wall between the two areas. What you need is a wall conforming to MSM (Mass-Spring-Mass)…
  • BriHar, 25 September 2012Obviously it's going to be PITA if you have to take down the framing again (unless you do want to address the decoupling issues). So here's an alternative. You could…
  • FriFlo, 25 September 2012Ok, this is really helpful! Thank you so much! A few things to be sure: 1) Just to get the whole idea right: you are saying the MSM thing won't work, when I have mass…
  • BriHar, 25 September 2012I get the impression that we're not yet quite on the same page, so let me try and answer your questions. 1. Only MSM. One leaf of gypsum board will have to come off the…
  • Soundman2020, 26 September 2012Correct, because that would not be MSM: that would be MSMSM. That's a three-leaf wall, which will always isolate WORSE than the equivalent two-leaf wall, all other…
  • FriFlo, 26 September 2012Thanks for chiming in as well, Stuart! I really appreciate that! And please excuse my ignorance ... Still, a few questions remain regarding that wall: What is the…
  • FriFlo, 26 September 2012No, it wouldn't be to much of an effort to unscrew the poles of the new frame to remove the plates from the tracking room side. So, I will remove those. I am not to lazy…
  • FriFlo, 26 September 2012Hopefully, to make the interaction between ceiling frame, old wall frame and new wall frame a little clearer, let me add these new pictures: Image not preserved:…
  • FriFlo, 26 September 2012I called my building center. I may bring the 1.4 cm gypsum boards back and buy fermacell instead. But they only have 2cm plates (1,5x0.5m), which are actually made for…
  • BriHar, 27 September 2012I would strongly recommend you get a copy of Rod Gervais' Home Recording Studio, Build it Like the Pros In addition I propose you post some detailed cross-sections of…
  • FriFlo, 27 September 2012Very helpful! Thank you. I'll look into that, but might not be able to read (and understand) the whole book before doing at least this wall. :-) Will do! The old drywall…
  • Soundman2020, 27 September 2012I hope this doesn't come off as sounding harsh and unfriendly, since that isn't the intention at all. Quite the opposite. But here goes anyway: Stop. If you build that…
  • FriFlo, 27 September 2012I agree with you, that I indeed should take the time to study a book like that completely. I am not at all insulted by this. Both of you have been so kind and patient…
  • BriHar, 28 September 2012The main reason I suggested Rod's book is primarily because it is one of the most practical (real world) works in this area, doesn't get too deep or involved with the…
  • Soundman2020, 28 September 2012Exactly. The manufacturer of the rubber should publish the basic numbers here, which tell you how much the rubber must deflect ("squash down") in order to float. It will…
  • FriFlo, 28 September 2012I am already reading the book you recommended and I must say THANK YOU!!! again. It is really way better than all the others before. I don't have any problems…

  • FriFlo, 28 September 2012Stuart, I think this is no problem. Germany is not known for heavy earthquakes! ;-) In my 35 years I never experienced a single one. My mother told me of one, which made…
  • FriFlo, 27 February 2013Hi guys, back again for more trouble! ;-) While I hopefully start soon on the soffit mount in my mixing room, I would like to think two more things a little ahead of…
  • Soundman2020, 27 February 2013That doesn't matter. You still cannot leave a wall unattached to the floor. Earthquakes are just an extreme example, but ANY type of vibration can cause the wall to…
  • FriFlo, 27 February 2013Thank you for your generous answer, Stuart. About the older topics: this is all good now. The separation wall is drilled to the floor with some heavy bolts. It is more…
  • Soundman2020, 27 February 2013Replacing the ceiling is actually not that hard to do: it's just a pain in the neck! Literally: You are looking up all the time, so your neck gets tired... :) Seriously,…
  • FriFlo, 27 February 2013Ok, good to know. I just have a lot of respect for that, because I have never done a drywall ceiling especially with multiple layers, that is quite a lot of mass above…
  • Soundman2020, 27 February 2013The easiest way to do it, is to rent a "drywall-lifter", which is a mechanical device that raises up the drywall to the place where you need it, and holds it there,…
  • FriFlo, 28 February 2013I am so sorry! But I already got another list of questions: You strongly suggested to use a resilient channel. As I understand the RC1 it is there for decoupling the…
  • FriFlo, 3 March 2013Another thought on my ceiling: Since I have no problems with the neighbor above and the currently installed hung ceiling with just one 12mm layer of gypsum without any…
  • FriFlo, 3 March 2013And this is the video, where it is explained. http://www.realtraps.com/video_demo.htm Meets pretty much my requirements, as I also don't need to isolate and have a…
  • Soundman2020, 4 March 2013Yes, you have already explained that, but you have also said that you DO need isolation between the control room and the tracking room: " The only isolation I need is…
  • FriFlo, 9 March 2013Since i figured out I will create a soft ceiling, it is time to find out what material to use. I chose a molleton cloth cover (300gr/m2, does not easily burn and I like…
  • FriFlo, 11 March 2014Hi guys! It took quite some time, but now I am ready for the next stage of my studio build. I finished most of the front with the exception of the hangars and mineral…
  • FriFlo, 12 March 2014A little addition: for the back of the mixing room I plan to make the entire backwall a shelf with about 60cm of depth. This way I hope it will become easier to get the…
  • Soundman2020, 12 March 2014Based on the REW graphs, you have some major modal problems, which is not surprising since you don't have any bass trapping at all in there yet! Also to be expected is…
  • FriFlo, 13 March 2014Thanks so much, Stuart! I don't know what this place would be without you ... :-) It really helps to see, that it is after all no magic involved, just analyzing the…
  • FriFlo, 16 March 2014And one more thing regarding the back wall becoming a porous absorber (as insulation covered by textile can only be a porous absorber): to be effective for a specific fq…
  • Soundman2020, 17 March 2014Well, that's only partly true, and only for "normally incident" sound, which means sound waves that strike the front surface of the absorber head-on, at an angle of 90°.…
  • FriFlo, 18 March 2014That is good to know, Stuart. Thanks! Unfortunately, the German forum with the VPRs is closed, because the admin has somehow disappeared. But I managed to email one of…
  • FriFlo, 23 March 2014To make the over all picture easier to understand, here some designs. This is approximitely how I would approach design A without bass hangars: frame to hold textiles…
  • FriFlo, 23 March 2014And here goes version B: A similar frame, but in with a depth of 50cm. I already improved the space for door opening in this version. Image not preserved: Back Wall B…

  • FriFlo, 29 March 2014And what about the bass hangars ... Do they make any sense at this size and their position? I also wonder, if it it is necessary to have a closed compartment with only…
  • gullfo, 1 April 2014i think some of this decision will be based on how much storage you actually need, since the more storage you place there, the less space there will be for absorption.…
  • FriFlo, 1 April 2014Thanks Glenn! So, if I got you right, with the shelf Doors this could be working, maybe comparable to or Even better than to the A design? I do not intend to stuff the…
  • FriFlo, 1 February 2015Hello again! After using the studio without any further acoustic treatment added, I have gotten some money together and finally installed a ventilation system to the…
  • FriFlo, 3 February 2015Ok! I am one step further. I did some experimentation with different mineral wool and found out, that a to layer of Termarock 50 over the light insulation in bass traps…
  • FriFlo, 26 February 2015Ok, I think I have gotten another step further towards a good sound! Bass trapping in the back (except for the absorbent doors in front of the shelf) and in the front…
  • FriFlo, 1 March 2015Thanks Glenn! So, I thought of one last idea (apart from the shelf doors with 10 cm basotect): I could build an absorbing door (actually just a frame with door handle)…
  • Soundman2020, 9 April 2015That would work just fine. It doesn't matter how you build them: as long as the dimensions, spacing and cavity depth are correct, that's all that really matters. Not…
  • FriFlo, 9 April 2015Thanks Stuart! Ok, I get it. So, where some of those slot resonators would be good, is for the mid frequencies. If you look at the pictures of my room response - which…
  • Soundman2020, 24 May 2015For the areas closest to your ears, I would go only with porous absorption. Slot walls do several things at once, and you don't want that happening around your ears. By…
  • FriFlo, 2 August 2015Ok! Now I am about to start the last phase! So, plastic ... I have some problems with that: The biggest area of porous absorption in my control room is the ceiling,…
  • Soundman2020, 3 August 2015That's because the plastic never is the top layer!!! The plastic is not visible. You put it over the insulation, BEFORE you put the cloth on the front. So you never see…
  • FriFlo, 23 September 2015So, here I am back again ... :-) Recently, I had time to build some more absorbers and since the reflections of the surround monitors to the left and right were the…
  • Soundman2020, 14 November 2015Yes it is. It's too low for that size room. There's too much absorption overall, so you'll need to use thicker foils, or maybe make some parts into slot walls (taking…
  • FriFlo, 22 November 2015Thank you! That is exactly what I have been looking for. And it matches what I am hearing: The bass is a lot more defined with all the absoption in place, but it is…
