Figures

FIG. 1.

So and detection thresholds (dB SPL) obtained in “the quiet” as a function of the duration of the signal. The data represent the thresholds averaged across four listeners. The average standard error of the mean across the 12 points displayed was .

FIG. 2.

threshold S/N (in dB) plotted as a function of the spectrum level of the broadband Gaussian noise masker. The data represent the thresholds averaged across four listeners. Error bars represent standard error of the mean. The parameter of the plot is the masker/signal duration.

FIG. 3.

threshold S/N (in dB) plotted as a function of the interaural correlation of the broadband Gaussian noise masker. The scaling of the abscissa has been expanded for the largest values of in order to preclude overlapping of thresholds that could obscure the patterning of the data. The data represent the thresholds averaged across four listeners. Error bars represent standard error of the mean. The parameter of the plot is the masker/signal duration.

FIG. 4.

A replotting of the data in Fig. 3. Threshold S/N (in dB) is plotted as a function of masker/signal duration. The parameter of the plot is the interaural correlation of the masker.

Panels a and b contain a re-plotting of the data (symbols) depicted in Figs. 2 and 3, respectively. The predictions of the data derived from an iterative computational procedure (see text) are indicated by the solid lines. The parameter of the plot in each panel is the masker/signal duration. The dotted and dashed lines in panel b represent the So and quiet thresholds, respectively, replotted from Fig. 1.

Tables

Generic image for table
TABLE I.

For each spectrum level of the broadband diotic external noise masker (columns 1 and 2), the table lists the parameters of the internal noise computed by the analyses (columns 3 and 4). Based on the assumption that the external and internal noises are combined, the last two columns list, respectively, the increase in effective power produced by the addition of the internal noise to the external noise and the effective interaural correlation of the combined external and internal noises. (NM: not measurable.)
