Figure 4.

(A) Peak instantaneous TMRs at threshold in the best 1∕3-octave channel [derived from Fig. 3a by applying the instantaneous TMR benefit corrections, listed in the inset, to both colocated and separated thresholds of both Experiments 1 and 2] (B) Modulation depth (across-subject means and within-subject 95% confidence interval) at the threshold TMR in the three modulation conditions in which modulation of the target and masker differed. Data are compared to predictions based on the data of Wakefield and Viemeister (1990)—WV, Dau and Ewert (2004)—DE, Viemeister (1979), and Dau (1996)—D. The legend of panel B applies to data in both panels and to all modulation conditions.
