Equivalent rectangular bandwidth
The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics.
Researchers have derived a differential equation giving the ERB value  in Hz of a human auditory filter with a center frequency of  kHz
-
Solving this equation gives roughly the following relation between the ERB value and the frequency in Hz:
-
Or the converse:
