Another Garage question

John - I am converting a garage (how original). I want to stop taking every project to a large commercial studio. The gasrgae is an old 2 car with one car door. The other half is basically open space (I guess for a workshop area). I want to partition the space so that the "workshop" area is enclosed. The siz will be 9'x13'. At the upper end of it, this will leave a 9x4 "nook" which will be partitioned into a 5x4 voxbox and a workbench. The car area will remain a car area aith a garage door, but I will treat the walls according to your suggestions for use as an occaisional live room for a drum kit or something. My garage is detached from the house and near nothing. My neighborhood is xtremely quiet. SOundproofing is probably not a huge issue except for the voxbox. Can someone do a sketch of the best way to make the 9x13 control room/project studio sound the best? Thanks ever so much!

Two key things for your control room........... 1) No right angles 2) No parrallel walls If you position the room right, the rest is mostly down to acoustic treatment. Just make sure, if you're putting a window out into the live room, that you slant the glass at an angle, to keep sound from directly reverberating. If you do that, the rest is mostly left to acoustic treatment (bass traps, diffuersers, absorbers, etc.) I'm just in the plannig stages of building mine. But I've been in a few studios, and those are the two important things I was told (by numerous people). Good Luck.

greetings hmmm? :) point 2] might diminish flutter echo a bit, which after you've done the acoustic treatment wont' be there even in a parralleled walled room. Non parrallel walls WILL NOT get rid of standing waves, which are the main reason for a non flat freqeuncy response. Some control rooms are built with extremely splayed side walls and front ceiling to direct early reflections away from the listening position, but it's an awful lot of work and hassle, when the same can be achieved by decent absoprtion panels in the right places. Slightly splaying the walls IMO is pointless. Unless it's done for aesthetic reasons :) The space gained by keeping the room rectangular, can be utilised for lots of broadband standing wave absorption. Plus the room itself is a LOT easier and cheaper to build. Slanting glass: If your employing a double leaf glass window ( which you would be wth a double leaf wall between rooms ), then you want the biggest airgap you can get. slanting the glass compromises this. Sound hits a surface in a room at many different angles not just perpendicular btw Paul
