It was a long time ago when I built my studio. We built 4 walls between the control room and the live room. Each pair with a pane of glass in them. I wasn't aware of the 2, 3, or 4-leaf design back then. Is this still a good idea or a bad idea? I searched but couldn't find anything.
Thanks.
Here's what I built in 1988:

Using two 2-leafed walls together?

I'm sorry, I should have been clearer. One of these walls on the live room side and the same on the control room side with an airspace.
If I understand you correctly, it's still a bad idea. However, if you have two layers of 5/8 drywall on EACH leaf, as you seem to do, with large air gaps, then you probably have enough mass and air to compensate for the 4-leaf effect, so my guess is that you'll still get reasonably good isolation. Of course, since it is already built, the question is: Does it work????!!! How good is the isolation between rooms? Are you asking because you are considering re-building the studio for some reason? If so, then you could re-do that and save some space, and there are a couple of other things you could change that would improve the CR greatly. Basically, you could re-build it as a modern RFZ design, instead of the way you have it now: The state of the art in acoustics has changed over the last 20-something years, and what you have is no longer considered good. Firstly, compression ceilings aren't really used much any more (questionable functionality), and the other biggie is that your CR side walls seem to be splayed backwards! The room should be narrower at the front, spreading to wider at the back. Your plan seems to show it the other way around... I wouldn't think would be good acoustically. But if it works for you the way it is, and the CR has good flat response, with low and even RT-60, and you aren't planning on upgrading/remodeling anyway, then I wouldn't sweat any of that. If it ain't broke, don't fix it, as they say! Really nice looking studio, by the way! That live room looks fantastic! - Stuart -Is this still a good idea or a bad idea?
