Hello, After reading a lot on this forum and reading Build it like the pros i still have some questions about floating floors. I want to build my new mix/recording room in my new house on the first floor. The walls and floors/ceilings are made of 25 cm concrete, on both sides i have neighbours. The room in which i want to build my new studio is 2.66m*4.8m*5.45m. I want to use the room for mixing, recording vocals, acoustic guitars and percussion. Do i have to isolate the walls and floors so i don't disturb my neighbours? I read a lot about floating floors, and most people say it is a waste of money, so does anyone have experience with Agglomer floors? Best Regards, Peter |

I checked the drawings from my house, the floor/ceiling is 25 cm concrete with 5/7 cm sand/cement chape finish. They called it "tunnel bouw"in dutch see the pictures. http://www.joostdevree.nl/bouwkunde2/tunnelbekisting.htm I called with merford in the Netherlands, they told me that agglomer would do the job.... What would be the easysed solution to build this floor. My idea was to build a box in a box. Best regards Peter |

And what about HOMATHERM silentTop Post by: franman on January 27, 2010, 10:05:01 PM 1. Yes, you should (properly) float your room given your adjacency. 2. Proper floating floor isolation is not for the faint of heart!! Maybe you should get a consult from Thomas?? 3. Don't be looking at the residential sub floor products. They are really not applicable to low frequency isolation requirments in studio applications. They are more about Impact noise isolation. Do it right the first time, or else skip it. Otherwise, it is a waste of money.

Best Regards, Peter Post by: franman on January 28, 2010, 08:41:05 PM Be careful. Look at information from Mason Industries. They have a fairly good tutorial available online geared towards architects, that explains the engineering required for proper structural decoupling. Check it out... http://www.mason-industries.com/masonind/private/ARCH/arch_m ain.cfm This is a much better primer than that SAE nonsense.... FM Post by: Constantin on January 29, 2010, 05:50:17 AM I will add another link about it: http://www.earsc.com/HOME/engineering/TechnicalWhitePapers/V ibration/index.asp?SID=61 Another problem of woodflorrs are the static wight. Remember you need MASS for good isolation, and i am not sure if 2 layers of 16mm plywood will do the job. I used in my vocalbooth 2 layers of high compressed 38 mm HDF, which is realy heavy, and make the airgap realy big to bring the MAM reaonance as low as possible. YOu have not the celling hight for this option. MAM resonance is still not in a for music with much bass, needed area, but ok for vocal tracking since i cut anyway all under 80hz. For a control room this is not an option, so you need more mass, and bigger airgap. The decoupling is another story, where thomas or fran may can tell you more cheers constantin Post by: Thomas Jouanjean on January 29, 2010, 09:25:50 AM Giving away the goooood stuff Post by: PeterDraaisma on January 29, 2010, 11:48:16 AM I'm thinking after looking at the pictures if it is even possible to do it (don't make the joke ha ha) in a room from 2.66m*3.8m*5.45m..... Fran and Thomas, did you ever designed a good sounding and isolated small room studio? Best regards Post by: franman on January 31, 2010, 09:58:55 PM Of course it's possible. We do rooms that size all the time. We would not be using 250mm Floating Floor systems, but it is possible to get 'good' isolation. You have to work with what you have and what the site will support (what will fit) and then you (or the client) has to understand what performance to expect.!! That's the important part. FM Post by: PeterDraaisma on February 03, 2010, 05:24:36 PM Great to hear that it is possible to get a good room in my house. Do you have pictures of such rooms on your website? I only have seen big rooms on your site. Best regards, Peter Post by: franman on February 03, 2010, 10:13:24 PM Post by: PeterDraaisma on February 11, 2010, 03:43:51 PM I know how to treat the room with bass traps, reflection free zone etc. But are there easy and cheaper solutions to disturb my neighbours as little as possible. Would a carpet floor help? Or such a thing as the poor man's floating floor as discussed on gearslutz... Btw, Fran those wide-angle lens rule, i thought that the room was way bigger:-) Best regards, Peter |
