I'm currently building a drum room/iso booth for my studio. I have a 10'X10' room for it. The way I plan it all to go down is this:

I originally planned to put up eggcrate foam on all 4 walls and the ceiling. I have interlocking foam tiles for flooring. I'm putting a window in the walled shared by my main open jamming room and this iso room. All I want is a dead room with no room noise for recording vocals, drums, guitar amps...etc.

I've finally decided to put up grey commercial carpet on all the walls ad ceiling and make some acoustic tiles and strategically place them around the room; deflecting sound in corners, bass traps, a few panels on the ceiling. I'm looking forward to when it's all said and done.

Any thoughts? Anyone done anything like this before?

(I'll post some pictures of the process, I think)
