i've made a quick simple drawing of my control room
it's 12.5'x12.5', 8' 3" celling
cement rendered brick walls, 5" concrete celling, floor is 1/2" marble on a 10" concrete foundation.
the door in grey at the upper left corner goes to my tracking-practice room.
i know the identical wall dimensions suck, but walls are load bearing so if i remove one the 2 upper floors fall on my cheap gear, and i feel the room is quite small as it is so if i do a room within "this" room, i could end up with a soundproof closet.
altough i don't need a lot of isolation from the outside, i would like to have some between the control room and the tracking room; right now i have to gess when i set up drum mics, record a little and then go again and change mic placement to avoid phase problems.
now with the questions:
- how much isolation could i espect if i remove the door to the tracking room and close the opening with brick rendered at both sides?
i've read the STC chart at SAE but i don't know how much structural born transmission would affect that performance 'cause the rooms aren't structurally isolated from each other (read totally coupled)
-taking into account my horrible perfect square room, would i get a noticeable improovement when mixing by building the two angled slat resonator walls showed in red in the drawing?
i think they'll take care of standing waves between the parallel side walls and reduce modal problems because of the two equal wall dimensions, but what do i know.
-the angle of the resonator walls should be 6 degrees each to get 12 degrees of diference between them, or should i angle them even more.
-looking at the small distance between the sweet spot and the rear wall, should i cover most of it with broad band absorption?
that's it for now
thanks for your help
