Hi, I been doing research and I'm been hearing a lot about the "golden radio" I been finding some bits and pieces of it ,most say L. W. Sepmeyer model is the best to follow was just wondering if there is a chart somewhere, the space I am building in building in is 18x13x20.
Golden rule help for room modes

do a bit more searching here. there is a lot of information about room ratios with Sepmeyer being just one of the options. golden ratios are typically not used for room acoustics but more of aesthetics. that said, room ratios are only part of the equation in designing and building your studio.
ok, I have done several, but they contain many gifford gaps and bonello. Kinda frustrating trying to get a room that works. This is for a school project and it's almost due, we were basically given two rooms in an existing building with max room dimensions to work with, then taught about giffords and bonellos, then absorption with regards to Sabines. As I said my major issue is getting past the giffords and Bonellos, one of the TA said their was a "ratio" to use that would help get a perfect room, and to look for it. I slightly confused with your statement with regarding to aesthetics. It seems everything I find seems to contradict something else I find which in turn adds to more confusion.do a bit more searching here. there is a lot of information about room ratios with Sepmeyer being just one of the options. golden ratios are typically not used for room acoustics but more of aesthetics. that said, room ratios are only part of the equation in designing and building your studio.
Even with perfect dimensions, the room is going to get clutter with equipment, bodies, furniture, groupies, etc and then all bets are off. So to compensate for the invariants, studios also need a balance of treatments to ensure the room response remains as stable as possible. So ratios are only part of the equation. To explore this ratio topic in depth, check out Eric Desart's most excellent treatises on the studio tips forum.
The problem is that too many people think there is a simple "perfect ratio", which does not exist. Unfortunately too many people who should know better think the same way. The goal is a smooth transition from the diffuse field region down to the pressure zone. IOW Bonnello criteria. A good summary is on these pages. For a bunch of "best" room ratios look at Cox's best ratios excel file here. Smoothly, Andreone of the TA said their was a "ratio" to use that would help get a perfect room, and to look for it.
