As I understand it, the golden ratio applies only to rectangular rooms. It’s also quite problematic to apply. I’m hoping to avoid the problems the ratios try to solve by starting out with an asymmetrical room.
Here are some considerations, entirely without input (so far) from acoustic professionals:
- the walls, floor and ceiling should be rigid so they will not vibrate and contribute to the sound. This is important for the low notes.
- The floor perimeter dimensions should not be a perfect rectangle with parallel opposite walls in order to prevent standing waves - cancellations of some frequencies and boosting of others. Would rounded space like a band shell be best?
- Would a stable 3D sound stage be more likely in a room that has a physical stage facing a room that widens into the listening area?
- Then there are the livelyness and brightness issues which will require carpeting of some of the surfaces, the floor to start. How about the ceiling or the back wall?
Thanks for your input,
Peter
