Critical-band rate correlates with pitch, frequency discrimination, and basilar-membrane position.

Evidence

The critical-band rate is closely related to several other scales that describe characteristics of the hearing system. For example, both the justnoticeable increment in frequency and the threshold for frequency modulation are closely related to critical bandwidth. Although this relation is discussed later in Chap. 7, the frequency dependence of just-noticeable frequency variations may be compared with that of critical bandwidth. Furthermore, critical bandwidth seems to bear a relation to the function relating frequency to ratio pitch, and to the function relating frequency to the position of maximal stimulation on the basilar membrane. — Professor Dr.-Ing.
