FIG. 1.

Data from experiment 2 of van de Par and Kohlrausch (1998). Mean thresholds (four listeners) for detection of a tonal signal in a 25-Hz wide band of noise, constructed such that the presence of the signal created either interaural phase modulations (squares) or interaural amplitude modulations (circles). Error bars are one standard error of the mean (n = 4).

FIG. 2.

Data from the main experiment. Each panel shows mean threshold modulation index as a function of center frequency at different modulation frequencies. Open symbols are data observed when flankers were included in the stimuli and closed symbols are data with the flankers absent. Squares are thresholds for interaural phase modulation and circles are for interaural amplitude modulation. Error bars are one standard error of the mean (n = 4).

FIG. 3.

Mean data from the conditions with no flankers (symbols) plotted against the predictions for the same stimuli of a model (black lines) based on that of Bernstein and Trahiotis (2003) using parameters fitted to the same data. For the data, means are averaged across four listeners. The predictions of the model using Bernstein and Trahiotis’ low-pass filter and compression parameters are also shown (gray lines).

FIG. 4.

Mean data from the conditions with flankers (symbols) plotted against the mean predictions of the same stimuli of a model (black lines) based on that of Bernstein and Trahiotis (2003), but using parameters fitted to the data for no flankers.

FIG. 5.

Mean data from experiment 2. Error bars are one standard error of the mean.

Image of FIG. 6.
FIG. 6.

Log mean-squared error of the peripheral-nonlinearity model fit is represented by symbol size as a function of low-pass cut-off frequency and compression exponent. Gray symbols are fits with fixed values of cut-off frequency and compression exponent in which only threshold internal interaural correlation was fitted. Black symbols are different fits in which all three parameters were fitted. The parameters from the third of these points were selected for use in generating Fig. 3 due to the close correspondence of the fitted compression factor with that used by Bernstein and Trahiotis (2003).
