separating the control room from the tracking room

Posted: Sun Feb 09, 2003 4:02 pm

I am planning to put a soundproof wall in my downstairs studio. The dimensions now are 19'x19'x8' feet high. The wall im putting in is 12 inches thick and I was going to put it right down the middle cutting both sides down to 9'x19'I have done extensive reading on studio building and acoustic treatments and i am aware of the problems of standing waves in such a small space, especially with parallel walls. But i was wondering if the dimensions of the room are acceptable. My purpose for the room is to record the typical things such as bass, guitar and drums. any input on this problem would be greatly appreciated
Thanks
Wes

Hello Wes, I left you a message earlier.

You have nice sound where you are.

If you can stack enough stuff at the end of one wall to cut it down to a 14X9 then it would be better....or stacking at both ends, instrment cases, bags, soft things..or get some traps.

9X19 is not good as it is a large squarish tube. You would have nodal problems..just reduce to around 14 on the long end it will sound better.

Thanks Bill,
I'll try that.

Hey Wes,

You could always try building your control room into a corner, maybe make a longer front wall joined with two shorter walls angled back 45 deg. (Forming a 135 deg. angle between your front wall and the side wing walls). Imagine the side profile of a round-cut diamond. You could then put a really nice corner bass trap directly behind your mix position. You could even soffit/flush mount your monitors to save space if their design is such to permit it.

This would also give you more room in your tracking room and practically no parallel surfaces (except floor to ceiling). With baffling you could get decent separation (if you desire) and still let the players maintain eye contact.

Just some food for thought.

Scott, Sorry, but don't do that!!! Rule #1, never fire into compression. If anything you want the room to become larger behind the listening position. I learned this from John Storik. ... Fats

Wes,

> I was going to put it right down the middle cutting both sides down to 9'x19' <

I agree with Bill that the approximately 2:1:1 ratio is not ideal. Making one "half" smaller than the other will help.

> i am aware of the problems of standing waves in such a small space, especially with parallel walls. <

It's worse than that. Surprised

Even larger rooms and rooms with angled walls have low frequency problems, caused by acoustic interference as the waves bounce around the room. So any room that is to be acceptable for making mixing decisions will need low frequency treatment.
