Hi,

Any Cheap way to do the Vocal Room and Control Room Treatement? 12x13 ft (vocal room), 12x17 ft (control room) Height about 10-12 ft.

I got some friends told me to use the Foam which is using in the Roadcase Box.it's 2 inch thick.Do you think it's posible to use for Room Treatement Purpose?

What do think about Concrete and Solid wood?which is more useful for Room Partition for Vocal Room and Control Room as a base?

I'm wondering whether it's work or not as below..
-I gonna partition my Vocal Room and Control Room with Concrete Build,then Put on the Foam that my friend recommended 2 inch thick.

Do you think it's work for my Studio? :P

C'ld you please give me some advice on my Studio in the Cheapest way but effective way (please give me the link to understanding the meterial you recommended)?thanks ...

Concrete beats solid wood, but wood is easier to build with/transport than concrete. That being said jameshardy concrete products are dense and that is what you want, density.

You could build a wood studded wall(s) with the proper insulation in void areas. Then sheath the studded surface with jameshardy 4ftX8feet tall panels.
Then strip the walls with say a 1/2 inch furring strip and sheath the surface again with 5/8 inch sheetrock.

After the rock has been taped/bedded and floated out, caulking up all joint areas and cracks that remain with high quality caulk is a key element to stop movement/rattles and any leaks...in OR out.

But if you have the means and will to form up a concrete wall...it should deliver the highest isolation but may also become a reflective area from hell-O.

Just my 2 cents on the idea boss...good luck.

THe foam will be could for absorption of higher frequency but won't do anything for the lower range frequencies. Check out http://www.realtraps.com really useful site.

Thanks for the info.
So,did you mean that i still can consider the Foam??
The treatement will be this?? Concrete->FiberGlass->Foam??

i'm actually looking for easier way and cheapest way to build it.. ;)

so do you mean the Foam is a Good Isolation treatement but it'll be a Reflection oso?/QUOTE

I mean if you have a concrete structure sound will have to work especially hard to penetrate it and that is good BUT the concrete will also become a reflective area. Concrete is dense so things bounce off of it.

Grasscloth could help diffuse the sound waves which should help in your case to correct the reflective qualities of a concrete surface...if one exists.

My gawd, I sound like I just woke up!

There's actually a science to this type of thing.

Neither wood nor concrete are better. Each has its own characteristics.

Wood absorbs low frequencies (< ~125hz) better than any other frequency.

Coarse concrete absorbs low-mid frequencies (around 250hz) better than any other frequency.

DO NOT PAINT the concrete. This is what makes it so reflective.

Anyways, looking at the big picture, concrete still absorbs about 3x as many low frequencies as wood, but that doesn't mean you don't need wood. Things need to be balanced out.

Thin 1" fiberglass boards will absorb 90% at 1k, 95% at 2k, and by 4k, 98%. Once you get down to ~100hz, this will only absorb 6%.

However, 4" fiberglass boards will absorb 90-99% of sound at all frequencies.

Egg cartons or drapery on the wall will absorb best around 1k.

Just a little info that may or may not help
