Image of FIG. 1.
FIG. 1.

Geometric mean F0DLs for the target without any masker except the TEN. The open and filled bars show results for HCTs with cosine starting phase (C) and random starting phase (R), respectively. Results are shown for three frequency regions: Low (L), Medium (M), and High (H). Error bars denote one standard deviation (SD) across listeners. To calculate this, the SD of the logarithms of the individual F0DLs was calculated and the antilog was then taken to convert this to a factor. The geometric mean was multiplied by this factor to calculate the upper end of the error bar. Standard error bars would be shorter than the values shown.

FIG. 2.

Geometric mean F0DLs for the target in the presence of a spectrally overlapping masker. The open, filled, horizontally shaded and cross-hatched bars represent four combinations of target and masker phases: CC, CR, RC and RR (C: Cosine phase; R: random phase). The first letter denotes the phase of the target, while the second letter denotes the phase of the masker. Results are shown for three frequency regions: L, M, and H. Error bars denote one SD. Each panel shows results for one value of the difference between the F0 of the masker and the nominal F0 of the target.

FIG. 3.

(Color online) Excitation patterns (EPs) for the target without the masker. The solid line shows the EP for the higher-F0 target (fh) and the dashed line shows the EP for the lower-F0 target (fl). The dashed line is sometimes hard to see since it is very close to the solid line. The difference between fh and fl equals the mean measured F0DL. The starting phase of the components was cosine (C, left) or random (R, right). Results are shown for each of the three frequency regions. The Δ symbols indicate the point on the EPs where the difference in excitation level was biggest. The difference at that point is denoted ΔL, and is indicated in each panel.

FIG. 4.

(Color online) EPs for the target and masker for differences of ±3 and ±6 ST, for regions L and M. Results are shown only for phase combination RC. Otherwise as Fig. 3.

Image of FIG. 5.
FIG. 5.

Sum of the absolute values of the differences in excitation level for the fh and fl tones across the region of the EPs that was above the threshold imposed by the TEN, plotted as a function of the F0DL. Each panel shows results for one ST difference. The symbols indicate the specific condition, as indicated in the key.

Image of FIG. 6.
FIG. 6.

(Color online) Spectral Profiles (SPs) for the target and masker for the difference of +6 ST, for regions L, M and H. Results are shown for phase combinations CR (left) and RR (right). The solid line shows the SP for the higher-F0 target (fh) and the dashed line shows the SP for the lower-F0 target (fl). Otherwise, as Fig. 3.

Image of FIG. 7.
FIG. 7.

(Color online) Examples of temporal profiles (TP) for the F0 difference of −6 ST. The solid line shows the TP for the higher-F0 target (fh) and the dashed line shows the TP for the lower-F0 target (fl). The dashed line is sometimes hard to see since it is very close to the solid line. The phase combination was CC (left column) or RC (right column). Each row shows results for one frequency region. AU stands for “arbitrary units.”

FIG. 8.

(Color online) As Fig. 7, but showing summary autocorrelation functions (SAC). The lag axis has been converted to frequency (= 1/lag) to facilitate comparison with Fig. 7.

Image of FIG. 9.
FIG. 9.

Mean heights of the peaks in the TP at the fl and fh in the absence and presence of a masker with 0-ST difference. The filled bars represent the peak heights for the target alone. The cross-hatched bars represent the peak heights in the presence of the masker. The key under each bar indicates the test condition: L, M and H indicate the frequency region; the second letter indicates the phase of the components of the target; the third letter indicates the phase of the components of the masker. AU stands for “arbitrary units.”

Image of FIG. 10.
FIG. 10.

Heights of the peaks in the TP in the absence and presence of a masker with a different F0 from the target. Each panel shows results for one ST difference. The filled bars represent the mean peak heights at fl and fh. The horizontally shaded bars represent the peak heights at the F0 of the masker. The bars are positioned with the frequency corresponding to the peak increasing from left to right. Under each group of bars, the key indicates the test condition: L, M and H indicate the frequency region; the next two letters indicate the phase of the components of the target and masker. AU stands for “arbitrary units.”

Image of FIG. 11.
FIG. 11.

Ratio of heights in the TP of peaks corresponding to the target and masker for regions M and H and for each phase combination. Each panel shows results for one ST difference. The key under each bar indicates the test condition: M and H indicate the frequency region; the next two letters indicate the phase of the components of the target and masker.
