There seems consensus that angling the window panes between a CR and a RR does little to improve isolation between the two rooms.
It's advantages, apparently, are A) that it reduces flutter echo between the window pane and the wall opposite it. (Incidentally, does the reduction in flutter echo have relevance to the space between the window panes themselves?).
And B), it is better for eliminating lighting reflections - which is why many of us were taught to use black material on the inner frame.
But for A), why would angling the pane downwards be better than angling upwards? Especially if you want the main window in the side wall - rather than in the front wall - for better vision in the era of wide, frontal computer screens. Angling the window downwards reflects the waves directly towards the sitting engineer, while angling the window upwards would direct the waves to well above the sitting engineer's head and towards the ceiling and the trapping there. So why isn't upwards angling of the panes preferable?
