Your approach to this is really fascinating, but will take me awhile to digest.
I have REW and have used it, but have never seen a Spectogram plot of frequency v. delay (I'm using an old version). I would have thought those 2 little blips at 4.5 & 9 ms were benign! How did you identify them as side and cross side reflections? I see the 2nd graph (dbFS & distance) and surmise that corresponds to side and cross side distances plus your observations with "head turning".
Just so I'm clear, the chord length corresponds to the vertical height of the poly? I initially thought that the chord/arc was the horizontal width of the poly based on your original studio room picture. I'm guessing you did this for standing and seated positions, but that they would work oriented the other way?
I did not realize that polys do not alter phase unlike QRDs. I'm not sure whether that is good or bad if I'm trying to diffuse side wall reflections.
Anyway, you've given me (too?) much to think about and convinced me to upgrade my ancient version of REW. Thanks again for this!!!!
