FIG. 1.

Overall level of the masker needed for constant detectability of the 10-ms tonal signal as a function of the delay in the signal’s onset following the onset of the wideband masking noise (400 ms in duration). The data at the top are for a 3.0-kHz signal of 70 dB SPL; the data at the bottom are for a 4.0-kHz signal of 60 dB SPL. Each point is a mean of six (top) or seven (bottom) subjects; five subjects were common to the two sets of data; the flags indicate standard errors of the mean; and the short line segments illustrate the running average across successive pairs of delay values. For clarity, the abscissa spacing is different for the two ranges of values of signal delay. “Ovs” designates the difference between the 200- and 3-ms means (the overshoot). The corresponding data for individual subjects are shown in Figs. 2 and 3. The data for subject NN were excluded from both the 3.0- and 4.0-kHz plots because he showed minimal overshoot.

FIG. 2.

Overall level of the wideband masking noise needed for 79% correct detections of a 4.0-kHz, 10-ms tone presented at various delays after masker onset. Each panel contains the data for a single subject. The flags indicate standard errors of the mean. “Ovs” designates the difference between the 200- and 3-ms means (the overshoot). Because subject NN had minimal overshoot (bottom right panel), his data were excluded from Figs. 1 and 3. Each data point was based on three or four blocks of 50 trials each.

Image of FIG. 3.
FIG. 3.

Overall level of the wideband masking noise needed for 79% correct detections of a 3.0-kHz, 10-ms tone presented at various delays after masker onset. Each panel contains the data for a single subject. Note the different range of ordinate values for the middle pair of panels. The flags indicate standard errors of the mean. “Ovs” designates the difference between the 200- and 3-ms means (the overshoot). Each data point was based on 8–12 blocks of trials.
