Federico Miyara wrot this to me: The ERB, properly abreviated ERBS (since ERB stands for the bandwidth) is is another psychoacoustic scale but it is somewhat more restrictive and idealized than the bark scale. It is expressed in Hz. See https://ccrma.stanford.edu/~jos/bbt/bbt.pdf Maybe I misunderstood.
