FIG. 4

Effects of the introduction of background noise on model predictions. Signal level was held constant while the noise level was adjusted; SNR (dB) are described relative to the SNR used in the psychophysical experiment. For SNRs 5 dB or greater than that used in the experiment, the background noise has little effect on model predictions. As in Fig. 1, closed diamonds plotted along the top axis indicate that d0′ was not reached for the highest δ tested of 0.3.
