FIG. 7.

Signal detection thresholds (in decibels SNR) in diotic (N₀S₀—white) and dichotic (N₀S_τ—gray) conditions for A different sine wave frequencies (125 Hz—plain bars versus 375 Hz—hatched bars), B different noise bandwidths (50 Hz—plain bars versus 375 Hz—hatched bars), C different number of channels (one—plain bars versus three—hatched bars), and D uniform stimulus (plain bars) versus harmonic complex (hatched bars) on three channels. The size of the interaural delay in the N₀S_τ condition was dependent on the stimulus type and is indicated in the legend. Error bars depict 90% confidence intervals. Non-overlapping error bars indicate significant differences (also indicated with stars).
