sound proofing

Our studio is starting to look like it!
We built walls and now we are looking for glass to seperate the control room from the "cage".
But something that has been bewildering us since the beginning of our project is soundproofing.
For the walls that we built we used insulation inside of them. And the walls are pretty much sheetrock. We were imagining we would be buying some kind of foam and cover the entire cage.. everything including ceiling. But it seems that a. thats not how its done (people cover parts of their walls) and b. its pretty expensive (tho we have a budget to work with).
Any ideas to make it so the rest of the house is inmnune to the sound? (and also get the best acoustics possible inside the cage?)
Thank you

Aug 17, 2004 03:29 am The acoustical foam you speak of does not soundproof anything. Its purpose is to control reflections and smooth out such problems as standing waves.
To increase the degree of soundproofing it would have been best to learn about it BEFORE you built the walls, as there are several techniques that can only be applied while in the construction phase. But since it's already done, I can give you some tips on how to improve it.
First get a chaulk gun and seal EVERY crack you can find. Sound will travel through any opening, no matter how small. Chaulk the edges where the walls meet each other, the ceiling and the floor.
Next you should hang more sheetrock. I don't know what thickness of sheetrock you used for the original walls, but it was probably either 1/2 inch or 5/8 inch. Whichever you used, get the other size. You can hang it directly over the existing sheetrock or install "resilient channels" on your wall and hang the new sheetrock on it.
In an ideal situation, I would hang a layer of 5/8", then a layer of 1/2", then attach resilient channel and hang another layer of 5/8 on the channel.
If you are going to install glass, you need to use a double glass method. Get two panes that are different thicknesses. (Such as one 1/2" pane and one 5/8" pane. Install them on a rubber seal and space them a few inches apart. This will create an air cushion between the two panes and greatly reduce the amount of sound transferred from one room to the next.
The reason that using materials of different thicknesses is important is that all things have a "resonating frequency". They will vibrate sympathetically when a certain frequency is played. If the materials are not the same thickness, they will resonate at different frequencies and avoid problems of the materials adding to the sympathetic vibrations.
Make sure you use heavy, solid-core doors with rubber seals on them.
This is something to get you started. If you have any further questions, I will glady try to help you. I do freelance acoustical consulting along with my many other endeavors, and I'll help all I can.
