Wall Density Balance - Quick Help If Possible

In my studio build diary (2nd post) you can see my basic layout. The control room in the NW end of the building is a few inches away from the cinder block wall. Because the East side of this wall (and the west side of the Drum Booth wall) will form a hallway, I've decided to cover the outside of these walls with 1 layer of 1/2" drywall for appearance. I don't want to have exposed studs and insulation sticking out in the hallway. The inside walls will all be 2 layers of 5/8". My question is this: Should I also cover the BACK wall of the West side of the control room (where the splayed wall is) with 1/2" drywall so that the physical density of the two walls will be the same? I'm going to be building and standing up the West control room wall tomorrow so I've got to know if I need to cover it on both sides before then. Thanks, Len Morgan

Probably better if you don't; even if your block walls are solid, adding another leaf would make it a 3-leaf wall; if the blocks are hollow, you'd be going from 3-leaf to 4, still worse for isolation. Stereo imaging won't be affected by wall density, if that's what you're asking; the affected frequencies would be too low for directional behaviour... Steve

This was exactly my question. Thank you very much. len
