Controll Room Design, Sweden

Hi! I've been running my studio on this location for a couple of years now. I have never been happy with the sound in the control room. I never had the time or money to take care of it, but now I plan to fix it up. Location: Sweden, Jönköping. I the basement of a school. Originally built as shelter in the 70's. I have three rooms where one is used as control room which are the subject for this matter. Measurements: I don't have the prints for the structure, and i'm not sure there are any. But I did my best taking measurements my self. 5.5 x 2.9 meters, ceiling hight 2.6 meters. Materials: All the walls are plaster except for a pole of concrete. Floor is concrete with a plastic/rubber wood imitation carpet. Ceiling, painted concrete. The plan is only to fix the acoustics of the control room, not soundproofing or anything else. The soundproofing between the live room and control room are perfectly fine though I have no idea what's inside that wall. It was already built like that when I moved in. This is what the room looks like: I plan to use the right short side as front wall. Right now I'm facing the existing window, which makes it all very little symmetric. When I first moved in I used the right short side as front wall. But the resonance in the lower freq was killing me. (must I say I had no bass traps or anything) It just sounded better facing the long wall. And that's where I am today. No, I'm not very pedantic. I have a loose idea of what to. Inspired by a sketch by John on a room with similar proportions. I also plan to make a new window, cause to one today is very small and looks like crap. Here's a sketch of my idea. I have no idea what to do with the back wall. I also want to put in a new floor, wood or laminate. Maybe laminate is not good at all? I don't need to float the floor but if I can make it absorb it would be great. Any ideas and tips are welcome. I'm trying to plan this as much as possible before I start building. I can't afford to close down the studio to build for a very long time since it's my income. That's right, I have 16 pieces of these things 30x30x60 cm: Useful or not? Thanks a lot! Ulf

welcome! it looks like a good plan - just consider opening up the back of the soffit cabinets on the corner side so you can stack those corners with light insulation and they will function as bass traps. the foam units you have, consider using them on the wall-ceiling corners spaced apart, and any left over in the back corners. on the back wall (over the radiator and on the door - put some 100mm or 150mm absorbers. consider putting light insulation up around the pipes like a super chunk and cover with cloth. over the desk, definitely a heavy cloud. maybe a couple of clouds in the room.

Thanks very much for quick replay Glen! I figured I maybe scared a few away with the misspelled topic ;) Let's see if I can sort out what you said to me. Opening up the cabinets in the corners... do you mean something like this?: I guess the cabinet should be filled with insulation already. If I understood the model by John I used as guideline for this, the cabinet is split in two. Top part is with the soffit and filled with insulation, but no opening. Bottom part has an opening on the lower front, covered with fabric, to act like bass trap. But do you think it's better to oped the corner side instead, or also? Would it make any sense to fill out the gaps in the corners with insulation, like this?: How come you recommend to put the foam triangles spaced? I don't know if I can put any on the wall/ceiling corner above the door. There are fire alarm parts there. I don't think they are easily moved or allowed to be covered. I was thinking about putting them along the concrete pole on the back wall from ceiling to floor. What do you think about that? The insulation around the pipes, you mean like just making a larger pipe out of insulation and fabric? I already have clouds for the ceiling. Good to have something I don't need to build from scratch hehe. Good night! Ulf

that's the idea for the corners. the spacing on the triangles - exposes more of the surface and gives you flexibility in placement (like around fire equipment etc).

Yeah, but which example of corner was the one you meant? The one with open sides or the one with filled up gaps in the corner. Or perhaps both? I continued a bit on my sketch. Here's the updated version. I placed out some of the foam-triangles. and the yellow parts are insulation. Do you think this will work?

the spacing looks right. the triangles may or may not work effectively, but since you have them, why not try to use them?
