Well... room dimensions ratio... My understanding...
A room (enclosed space) is going to have nodes - frequencies that produce standing waves due to reflections. A Cube is usually quoted as the worst, same nodes in all directions, so they reinforce each other. I suppose a sphere would be the ultimate bad room.
The recommended room dimension ratios don't eliminate nodes, but, the nodes for end to end, side to side, floor to ceiling, and the angular reflections, occur at a range of frequencies, not falling on top of each other, not reinforcing each other.
I suppose if the room is bumpy enough it looks smoother, as opposed to one with a few totally black holes in the response.
Close your eyes and see if what you HEAR is as bad as what you think you see when you MEASURE, and go from there.
Musical intruments are not one frequency, they have harmonics and overtones. The ear/brain is adept at filling in the gaps.
I have a big hole at 55hz, and never guessed until I measured it. Didn't notice anything wrong. Now chasing it. That's the hobby.
If you want no nodes, you need an anechoic chamber.
I see the science boys have created the blackest material
yet, almost no reflectivity/emission for light. Maybe somebody is working on the same for sound.
