I need some advice on construction of the live room portion of my studio. The size is 12x12. I need to know if the quiet rock product is worth it? or should I just build out the second layer (room inside of a room) It has concrete floors and I didnt know if I had to false out the floor? On of the other things I was wondering about is what type of window (live to controll room) i should use and last but not least what kind of a door into the live room should I use for the best sound lock. please help

Best place to start is there. As for the floor, it really depends on how serious you want to get. I am on a carpeted concrete floor and am very happy with the room's sound. I use the Auralex brand foam on the wall's as well as sheetblock in the ceiling and then acoustic ceiling tile's. This room is not meant to be completely sound proof though and I have a regular door. That site will tell you all you need to know about the door and window you should require if you have the need for absolute sound proofing.
As for the use of the quiet rock. I know many studio's that use regular rock with the room inside a room config as you stated with very good result's.
Hope this help's ya a little.
And welcome to HRC, sorry I missed this post last night.
Dec 19, 2005 02:47 pm 12 x 12 is trouble already. You are going to have standing wave issues for sure with that room. Glass is cheap so you can just frame out a window. Use two peices of glass: a piece of 5/16" and 1/4". Some people will give the glass on the studio side an angle from top to bottom. Around the frame inside the glass you can put something absorbant: carpet, cork, or whatever. Depending on funds two solid core doors are always nice. But, as long as you have airspace in between them you will cut down sound trasmision drastically. Again in the sound lock you should put something abosorbanent. You can carpet the floor with the understanding that the low end will need to be treated. If you do decide to build up the floor I would put in some random dividers in between whatever you are using for floor joist. That is: If you are laying 2x4 on their sides at 16" on center I would put random didviders making differnt size cavities in between the joists. This will help keep the floor from resonating at the same fequency in every cavity. I would also put some sill seal underneath the joists and dividers to help isolate it from the concrete. But, what ever you can get your hands on, rubber roofing or whatever. But, sill seal is cheap and avalible at Home Depot or Lowes.

Dec 19, 2005 05:03 pm I'm in process of building as well. I read up on Sound Isolation Company, they are competing with the quietrock company, and don't have much good to say about it. They claim that they've replaced quite a few installations of quietrock, because it doesn't live up to it's claims.
I'm going with SIC's foam barrier, plus their sound clips, and channel. I'm going to put 3/4" pine for the inner walls, then 5/8 drywall on that.
They show on SIC that the $$$ for QR per sq. ft. is very high, compared to their solution (barrier, clips and channel). With their solution, they're getting 60+ stc, which seems pretty good. Hopefully i'll be a little better with the extra layer of dis-similar dense material.
One thing I've figured out doing this, is to do it right, (or at least, good) is expensive. I'm looking at around 2 or 3k$, maybe more. I've already pared down some of the isolation on non-important walls. It's a lot of work as well. I'm confident that it'll be worth it in the end though (damn well better be =).
A few of the sound / studio boards I've read is that the floor is probably the least of your worries. Good idea if you're realy building the top-notch soundproofing, but if you're on concrete basement, then it may not be worth the $$$ or time.
I'm not going to build a floor, just going with padding, and good carpet. I'm going to be putting in a control room, with two glass panes into the live room. I'm also going to be fastening some type of rigid fiberglass to my doors (covered, of course) to stop transmission to the control room, and/or isolation booth.
I'm probably going to have to treat the room with low end treatment like KT mentioned above, maybe a hermoltz slat resonator, maybe not, depending on how the room sounds when done.
There's another board I read up on once in awhile that the owner says he's found a way to tame low end in a small room, but he hasn't come across with info yet, says he's testing more. So we'll see.
Let me know if you're interested in more info I've gleaned from the net.
I've got a blog going on here as well,

maybe that'll help you out some.

Dec 19, 2005 05:05 pm oh yeah, Welcome to the HRC tourbus, glad to have you aboard.
Keep your hands and feet inside the bus at all times =).
Dec 20, 2005 08:41 pm Should I bother building up the floor? Is it worth it? KT could you explain making the window again? If 12X12 room is bad for sound what size should I build out?

Dec 20, 2005 08:44 pm I didn't read this thread, just the issue at hand. 12x12 is bad, as stated above. Get some things in the corners, like bookshelves, amps and such to help keep the bass from building up in the corners...and square rooms do have acoustical issues so on the flats of the wall be sure to hang some sound absorbing something...I built these www.homerecordingconnecti...story&id=50 and they have worked pretty well in controlling the sound in my basement studio.
Dec 20, 2005 08:45 pm Thanks everyone for welcoming me to the HRC
Dec 20, 2005 08:49 pm I am going to use that foam for the corners and going to put some some material on the wall. There a plenty of amps in there (or will be). Should I slope the ceiling or anything?
Dec 20, 2005 08:53 pm I hung those same sound control boards from my ceiling and it worked...but yes, sloping the ceiling wouldn't hurt.
The last pro studio I recorded in had big panels of brass-looking stuff urved slightly hanging from the ceiling to redirect sound waves in all sorts of directions...actually as I recall a puppet arm was hanging out from above one of those panels and the dude told us that was where he stashed the body of the last guy that stiffed him on payment :-D

Dec 20, 2005 08:58 pm Cash, the only place you might want to think about floating the floor would be the control room. But honestly it is not an absolute must do unless you are going for the supreme acoustic environment. I know many bigger recording facilities that dont have floated floor's in their control room's and they dont seem to be bothered by it.
Be very carefull in the big playing/recording room as to much sound absorbtion will not be good either. You do wnat a little of the room to be present when you record. The panel's dB made are a good idea in that environment as they can be made to be moved around if needed. I can attest to the fact the one's he made work great as I have been their before and after and it really did make a differance in his listening area.

Dec 20, 2005 09:00 pm Oh ya, ceiling. Are you taling about in the control room or the recording room?
Dec 20, 2005 09:18 pm in the recording room/live room
Dec 20, 2005 09:23 pm ok so I think that I WONT float the recoring/live room floor. The whole studio has bare concrete now, I thought I would use rugs or carpet absorb some sound.

Dec 21, 2005 07:13 pm I've seen the "room with a room" floated up off the concrete floor on old tires. Strangely, it worked.
Excessive?
Hell, yeah!
But we're all sensitive musician types here, we know nothing about excessive.....
Just interjecting....not really adding anyhing....
