Image of FIG. 1.
FIG. 1.

Mean L3 (dB SPL) for 3 dB of suppression as a function of f3 in octaves relative to f2. Data for a different f2 are shown in each row and data for a different L2 are shown in each column. No data were collected when f2 = 0.5 kHz and L2 = 10 or 60 dB SL, which is why those panels are empty.

FIG. 2.

(Color online) Mean L3 (dB SPL) for 3 dB of suppression as a function of f3 on a log-frequency scale. The parameter in this figure is f2 (squares = 0.5 kHz, circles = 1 kHz, triangles = 1.4 kHz, inverted triangles = 2 kHz, diamonds = 2.8 kHz, hourglasses = 4 kHz, ray-boxes = 5.6 kHz, and stars = 8 kHz). For f2 frequencies of 1–8 kHz, L2 ranged from 10 dB SL (lowest STC) to 60 dB SL (highest STC). For f2 = 0.5 kHz, L2 ranged from 20 to 50 dB SL. The unconnected symbols at the bottom of the figure represent the mean behavioral thresholds (±1 SD) at each f2.

FIG. 3.

(Color online) Compression (dB/dB) as a function of f3 in octaves relative to f2. The parameter within this figure is f2. These compression estimates were derived from the MLR and represent the ratio of the slopes for L3 and L2, which were provided in Fig. 10 of Gorga et al. (2011).

Image of FIG. 4.
FIG. 4.

Mean L3 (dB SPL) for 3 dB of suppression when f3 ≈ f2 (circles) and when f3 = f2 − 1 octave (squares) as a function of L2 (dB SL). Each panel represents data for a different f2 frequency.

Image of FIG. 5.
FIG. 5.

(Color online) Mean tip-to-tail (T-T) difference (dB) as a function of L2 (dB SL), with f2 as the parameter, following the symbol convention that was used in Figs. 2 and 3, as indicated in the inset. T-T differences were calculated by subtracting the L3 for 3 dB of suppression when f3 ≈ f2 from the L3 for 3 dB of suppression when f3 = f2 − 1 octave.

Image of FIG. 6.
FIG. 6.

(Color online) Mean QERB as a function of L2 (dB SL), with f2 as the parameter, following the symbol convention used in Figs. 3 and 5, and as indicated in the inset.

Image of FIG. 7.
FIG. 7.

(Color online) Mean BF (in octaves relative to f2) as a function of L2 (dB SL), with f2 as the parameter, following the symbol convention used in Figs. 2, 4, and 5, and as indicated in the inset.

Image of FIG. 8.
FIG. 8.

(Color online) Mean tip-to-tail difference (dB) as a function of QERB, with f2 as the parameter, following the symbol convention used in Figs. 2 and 3, 5–7, and as indicated in the inset. For each f2, the symbol closest to the origin represents data for the highest L2 level, with decreasing L2 as one moves toward the upper left corner of the panel.

Image of FIG. 9.
FIG. 9.

Individual STCs from 20 subjects for the condition in which f2 = 2.8 kHz and L2 = 30 dB SL. Suppression thresholds (plotted on the Y axis) were determined from SLR because data for only one L2 level are reported here.
