Yes, it's numbers and also subjective opinion. But we must know when to use each. Nobody can say if diffusion is "better" than absorption for some given situation. I like spaghetti and Joe likes burritos. But comparing surface reflectivity of different materials as discussed here is
entirely numbers. Boiling it down to the difference in dB versus frequency is
entirely numbers. Now, if you have two surfaces that reflect differently, then we can argue over which "sounds better" 'til the cows come home. But determining whether two surfaces differ enough to be audible is
entirely numbers. This is the domain of science, not subjective opinion.
