I really think you not going to be able to build a flaoting floor heavy enough and with a low enough resonant freqeuncy in order to stop any bass. Not without SERIOUSLY uprating the original structure. I'm sure you're poor sister doesn't want tons of studio crushing her to death. ;) If you swapped rooms so you have the bedroom as the studio ,and build a bedroom above for her, you'll stand a much better chance! PaulPaul, what do you think about my situation? (posted in this thread) Any idea? Thanks!
40 kg/m3 and 70kg/m3 rockwool for floating floor

Hi! :)
Last night I read the E.A.R document. But they say I need a "nomogram" to calculate the dynamic modulus(E)??
Do you know where can I find this factor for 36 mm of EPDM shore 65?
Thanks Paul! I can not swap rooms with my sister... that´s no really a choice. I have to make the best i can (and i can afford) to try to stop sound as much as possible... Can you give me some advice to achieve the best floated floor? btw, the original roof of my room was sloped, to solve it i added a cement layer to it... at least it´s a little more mass... :roll:I really think you not going to be able to build a flaoting floor heavy enough and with a low enough resonant freqeuncy in order to stop any bass.

Hugo, read my thread, I had exactly the same problem with data for EPDM. I discussed my project with Eric and Paul. Eric explained the DIY method to float floors with EPDM. (I think I already explained that stuff to you and gave you links... :roll: ) http://forum.studiotips.com/viewtopic.php?t=1586 Florian :DHi! Last night I read the E.A.R document.

Thanks Florian,
But you finally choose Sylomer instead of EPDM? No answer for EPDM "K" factor?
What happens with the SAE site floating floor method? I'm experienced with 2 of my rehearsal rooms. If atenuation material between joist has not enough density, floor resonance raises when play bass or distort guitar continuosly at 200 Hz aprox.
I explain my problem to you all: :lol:
A trash metal band rehears on a resonance floor at 200 Hz. Maybe is still so long. But they say it sounds like a BALL of sound.
What are the posible solutions??
1.- Take out the top of the floors and fill it with sand?
2.- Cover all the wall with absorvers?
3.- Take out the floor , and leave concrete floor?
Hugo, item 2 won't solve your problem. Item 1 WILL solve your problem and is the least expensive solution. Item 2 will ALSO solve you problem (within the room) but item 1 will leave you with slightly better sound isolation. You have to make certain though that your sand is bone dry - you tamp it well to make certain it's perfectly packed - and that you do not have any air space between the bottom of the plywood deck and the sand. You want full contact between the 2.
