i was confused when you wrote this. I did of googling and I think its just that, generally speaking, reverb times of single tones above the shroeder freq will be fairly even whereas reverb times of single tones below the shroeder freq will be fairly wildly different?
I may have it confused
Old thread, but just in case anyone who reads this wants to know. The Schroeder Frequency is where room modes are bunched so closely that they're no longer seen as resonant peaks. It is the approximate boundary between reverberant room behaviour (frequencies above Schroeder) and room modes (frequencies below Schroeder). The formula is:
Fs = 2000(RT60/v)^0.5
Fs = Frequency Schroeder in Hz
RT60 = Average RT60 and RT60 being the time it takes reverberation to drop by 60dB
v = Volume of the room LxWxH in m^2 (meters squared)
The trick is to not over think things too much. High frequencies you're worrying about reflections and the geometric behaviour of the room, and low frequencies you're worrying about room modes.
