The critical-band-rate scale mirrors hearing better than raw frequency
Evidence
As usual, we call the value we require “specific loudness” with the symbol N’. Loudness, N, is then the integral of specific loudness over critical-band rate (see Fig. 8.16 lower right) or in mathematical expression: 1 24 Bark N= N’dz, o where the integral is taken over all critical-band rates. — Professor Dr.-Ing.
