Q: Does Odeon have 1/3 octaves?

A: Odeon and other Room acoustics software are energy based high frequency models. Calculations are in 1/1 octave bands because it gives better results for energy based calculations.

In cases with wall transmission it is possible to use 1/3 octaves as input, but then Odeon will recalculate these to 1/1-octave bands in order to fit with the best calculation principle for this type of model.
