TABLE IV.
Thresholds for masker’s with asymmetric notches in the NNTC experiment. Subjects are labeled in the first column. The level of the signal or “probe” is presented in the column labeled “Lp.” In the remaining columns, the normalized notch-width values are presented in pairs, where the first number is the notch-width for the low-frequency noise band and the second is for the high-frequency noise band.
