Basement Drum room failure
« on: January 17, 2009, 08:58:47 PM »
Hello first timer here, hello everyone. I've got a problem i built a drum room which doesn't work. I started by insulating between the ceiling  joists with fiberglass insulation. I also put fiberglass insulation between the studs in the walls. I then fastened so called sound board to the studs and ceiling. I then used resilient channel on the ceiling and walls, i then fastened half inch drywall to the walls and ceiling.   I then coated the basement floor with plastic sheathing, then layed down  three quarter mdf then another layer of plastic then a rug pad then the rug. The drums are bleeding through everywhere furthermore i can actually hear people talking upstairs, when i press my ears to the walls.  The room is extremely lively which could easily be remedied with a few panels or foam. but i don't think this is the cure all. Should i do another layer of sheet rock to the entire room, yikes i've already painted everything. I have plenty of resilient channel left over. Some people have suggested just stapling ceiling tiles to the ceiling, but i dont think it will make any difference.  Would 4 inch foam on the ceiling and parts of the wall help. Any suggestions would be appreciated,  Thanks everyone.

There is a few reasons you are having this problem.
First off with a drum room you need a lot of MASS and the 1/2" drywall and soundboard is by far not enough Mass for this type of room, so adding more Mass like MLV, Quiet Rock or multiple layers of drywall will help.
Second, your decoupling with RC channel is ok but not good enough for a drum room,now since your this far into the project you can make that up by adding a dampening layer of Green glue between the existing drywall and the new layer your going to add. This will help reduce the low frequencies and resonence going through the wall assembly.
Here are links for you to review.

I would suggest to carpet the basement.
You get the most real sound whenn you carpet the walls and the floor.
Good luck for your sound control room :)

Well carpet is better than nothing but, no way could it compare with the NRC. values of open cell foams (Polyurethane Foams) for sound conditioning.
