Fig. 1.
Estimation of an auditory filter shape from the notched-noise paradigm. A: Psychometric functions for detecting an 8-kHz tone in a 30 dB/Hz masker, with g values of 0 (black), 0.1 (red), 0.5 (green), and 0.65 (blue). Threshold is the signal level that would evoke 0.76 probability correct (indicated by dashed lines). B: Thresholds from (A) plotted as a function of g (normalized deviation from center frequency). C: Auditory filter shape for an 8-kHz tone in 30 dB/Hz noise (from data in B). Dashed line indicates the half power point of the filter; the bandwidth of the filter at the half-power point was taken as BW3dB. Data are from Monkey B.
