Suggested formulae for calculating auditory-filter bandwidths and excitation patterns

B C Moore et al. J Acoust Soc Am. 1983 Sep.

Abstract

Recent estimates of auditory-filter shape are used to derive a simple formula relating the equivalent rectangular bandwidth (ERB) of the auditory filter to center frequency. The value of the auditory-filter bandwidth continues to decrease as center frequency decreases below 500 Hz. A formula is also given relating ERB-rate to frequency. Finally, a method is described for calculating excitation patterns from filter shapes.
