Figures

Image of FIG. 1.
FIG. 1.

Configuration of maskers and the tone in experiment 1 with 1 ERBN (top panel) separation of FBs and of experiment 2 with 2 ERBN (bottom panel) separation of FBs. The tone and the OFB masker were centered at the 16th ERBN and FB pairs were added symmetrically on the ERBN frequency scale to the OFB in different conditions.

Image of FIG. 2.
FIG. 2.

Stimuli waveforms of the OFB (top panel), a CM (middle panel) and an AntiM FB (bottom panel). The envelope of the tone is indicated in the top panel (light grey). Vertical lines are plotted to visualise the co-modulation and the π-shift of the minima of the AntiM FB with respect to the OFB.

Image of FIG. 3.
FIG. 3.

Thresholds of the tone as a function of the number of FBs in experiment 1 with unprocessed (left) and noise-vocoded (right) stimuli. OFB and FB separation was 1 ERBn. Results are presented as means across subjects’ individual mean thresholds taken across three repetitions of each condition. The error bars represent plus and minus one standard deviation of the means across the subjects.

Image of FIG. 4.
FIG. 4.

Thresholds of the tone as a function of the number of FBs in experiment 2 with 2 ERBN separation between FBs and the OFB. Results are presented as in Fig. 3 for unprocessed (left) and noise-vocoded (right) stimuli.

Image of FIG. 5.
FIG. 5.

Tone thresholds for unprocessed (left) and sine-vocoded stimuli for zero or four FBs present (experiment 3). Running noise was used in both conditions. Separation between FBs and the OFB was 2 ERBN. Results are presented as in Figs. 3 and 4.

Tables

Generic image for table
TABLE I.

ERBN number, center frequency (f c ), bandwidth, and lower (f l ) and upper (f u ) corner frequencies of masking noise bands used in experiments 1 and 2.

Generic image for table
TABLE II.

CMR results as the mean across all subjects (experiments 1 and 2; frozen noise stimuli). CMR values were obtained from the difference of the means across three detection thresholds measured for the conditions indicated in column CMR.

Generic image for table
TABLE III.

CMR results as the mean across all subjects (experiment 3; running noise stimuli). CMR values were obtained the same way as for Table II.
