critical ratio for masking (Fletcher critical bandwidth)

6.25  critical ratio for masking (Fletcher critical bandwidth). For a pure tone just audible in the presence of a continuous noise of constant spectral density, the ratio of the mean-square sound pressure of the tone to the noise spectral density . Unit,...

critical band

6.24  critical band. (a) For loudness, that frequency band within which the loudness of a band of continuously distributed sound of constant sound pressure level is independent of its bandwidth (see also 6.31); (b) For masking (see C11.31), that frequency...
