WebThe presence of critical bands in our ears is responsible for the masking of frequencies that are close to other louder ones that are received by the same critical band. In most sources, tables that estimate the widths of critical bands in human hearing give the bandwidths only in Hertz. In Table 4.4, we added two additional columns. WebThe scale ranges from 1 to 24 and corresponds to the first 24 critical bands of hearing.
