 How do we use these waterfall plots, especially at low frequencies if the RT60 become meaningless? |
The waterfall plots don't show RT60, they show the actual decay of each frequency across a band, which is what we need to see at low frequencies. RT60 is a single figure that summarises the decay across the entire band or some section of it (octave bands are fairly common), but a single number doesn't give any information about which specific frequencies are decaying slowly and which are decaying normally.
