Hello everyone! I'm opening a thread because I couldn't find a related topic on the forum.
In view of the planned construction of a new room, I remembered the acoustic "controversy" of the golden ratio.
If anyone wants to vent about it, feel free!

In mathematics, if two numbers have the same ratio as the ratio of their sum to the larger of the two numbers, they’re said to be in the “golden ratio.” If that sounds like Greek, don’t worry. The “golden ratio” in sound – more specifically in acoustics, doesn’t require you to understand the mathematical term and all its implications.
Instead, this ratio is related to set of ratios that tend to lead to the best acoustic response in a room, with a minimum of acoustic interference anomalies such as comb filtering, nodes, peaks, or dips. Knowing these ratios can help you to look for the best room in a house to put your studio or rehearsal space and are especially useful if you’re building a new space and can control the dimensions of the room

When doing a room the golden ratio is a set of many ratios made with irrational numbers. It is a nice one thou.
If you can slope the ceilig that will make much more difference.

Not all resonances are minimum-phase. Sometimes this won't matter, and sometimes it might.
You won't change the number of standing waves.
Perhaps you'll alter some discrete modes. Do you have a preference for which end you put the speakers or were you just saying in general?
It's not a matter of standing waves but to redirect Early Reflections above and around listening point. For this the angle needs to be 30* minimum.
You put loudspeaker on smaller side.
It's a nice step toward RFZ ( reflection free zone) but without using absorbtion ( i've seen people tell 'to rob energy to the room' it's naive but kind of describe the situation for me.)
At least this is how it's done in my room.

Reasonable.
A ceiling absorber is an option.

Ok. This will pull speaker output from a steeper angle. Presumably it would be reduced in level.. on the other hand it may in some cases be harder to ensure balanced output from the speaker at that angle, but if you do then good. It would also present to the listener at a more shallow angle.
It will increase there densitity as a single primary mode gets its energy distributed over a range dertermined by the amount of slope.
A figure of 85% was thrown our by an acoustics for the improvment in room issues and the room my hifi lives in is a solid example.

Originally at the tall end, everything was moved to the short wall, as that proved more dometically acceptable. Both sounded good, but the hifi has evolved a lot so nothing conclusive to say.
dave
I like diffusors over absorbers. If you cannot add suffieicent objects that do this, one can add specific ones.
