 I don't understand that question. Modal resonances are most significant at low frequencies, below about 200Hz. At higher frequencies they are still present but there are so many their individual effects are no longer easily resolved and dealing with them requires room treatment. |
Sorry for the very poorly worded question. I was looking for you to expound in this statement:
"I'd agree that a very "dry" (fast decay time) room is not good for music, though it can work well for movies. I also agree that for low frequency behaviour RT60 measurements are meaningless."
How do we use these waterfall plots, especially at low frequencies if the RT60 become meaningless?
Also, regarding your point on rapid decay being OK for home theater (this is because the surround effect gives ambience I presume). I think one could argue that movie sound track VLF tend to less discrete than music in general and are not as negatively impacted negatively by reverberation at low frequencies. Also, most of the VLF comes from the subwoofer, not from the surrounds, so wouldn't reverb in the low frequencies match better with the surround ambience in the higher frequencies? Total conjecture on my part...
Thanks,
Pete
