HTML document (modified by JT from a semitone conversion form written
and provided by J.R. de Pijper, IPO, Eindhoven) allows you to convert
frequency values expressed in Hertz to ERBs (equivalent rectangular
bandwidths) which express frequency in terms of psychophysical metrics
(based on the measurements of auditory bandwidths) (see Patterson,
1976; Moore & Glasberg, 1983; Glasberg & Moore, 1990). The
formula by Glasberg &
Moore (1990, p. 114, [21.4* log10(0.00437*f+1)]) is used here. Conversion
from ERBs to Hz is
