Comparison of fixed-level thresholds at a masker depth of -18 dB (closed bars) and roving-level thresholds, where the masker depth was randomly chosen from a uniformly distributed 10-dB range centered on -18 dB (open bars). Asterisks indicate cases where the difference between the fixed- and roving-level thresholds was significant (*p<0.02; **p<0.0001).
