Hey guys. I know many of you are interested in figuring out how various dimensions correlate to sound. This applies whether you're selecting a room, treating and troubleshooting it, quantifying your use case & selecting the treatment itself. All I'm doing here is sharing the link I always use as a reference.
Here it is: Physics of Music-Notes
To convert centimeters to inches, divide cm/2.54. To convert centimeters into feet, divide by 30.48.
I see a lot of questions about, "This is my situation, I know it isn't perfect but let's rack our brains on how to make it perfect using any and all esoterica." For better or worse, I don't know how to do that and I don't think anyone else does either. Please be realistic about your situation and use this chart as a guide.
To restate what I've seen, and barring extensive treatment, you need a minimum room volume of 2500ft3 for music and 1500ft3 for vocal work. Ideally, there is not duplicate or even-multiple dimensions. Ethan, and pasim I believe, have gotten great results for music on the smaller side but they know what they're doing and aren't in cube rooms. Bearing all this in mind, you should be able to make more informed and better decisions.
I want to add that I don't know exactly why you need a minimum volume for small rooms. Sizes less than 10,000ft3 are considered small rooms. I suspect it has less to do with the volume itself and more to do with boundary distance and modal distribution. The further the boundaries, the lower your lowest mode and hence the more distributed your support can be throughout the bass range. There's also boundary interference to consider as well as having room to find ideal placements. When I look online, all I see is talk about huge rooms with RT60 but, as Ethan has mentioned, that doesn't apply to small spaces. If anyone can chime in on that, I think this is a good place to discuss it.
Thanks.
