Convert reverberation time RT60 to decay rate in dB/s and to T20/T30 decay times.

How it works
Reverberation time is defined for a 60 dB decay, but measurements usually evaluate 20 or 30 dB of the decay and extrapolate. The decay rate links them.
Formulas
- decay rate = 60 dB / RT60
- time for X dB = X / decay rate
