Equivalent rectangular bandwidth
- Equivalent rectangular bandwidth
The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters.
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::
