Abstract

The schematic diagram and text erroneously omitted a component of the auditory-nerve model. A first-order low-pass filter with a cutoff frequency of 500 Hz was included in the feedback path within the model’s control-path, as shown here ~LP2, Fig. 1!; a scalar K with a value of 10 followed the low-pass filter in the feedback path. This low-pass filter was included in some but not all of the simulations shown in the original paper, as clarified below. The inclusion of LP2 did not significantly affect responses to pure tone stimuli ~Tan and Carney, 2003, Figs. 7–9,11,12! or to broadband noise ~Tan and Carney, 2003, Figs. 4,10!. The low-pass filter ~LP2! mainly affected responses to two-tone stimuli, and in particular was responsible for introducing the differences in growth of suppression for tones below or above CF. Figure 13 in Tan and Carney ~2003! did not include LP2; Fig. 2 here illustrates the effect of its inclusion. Figure 14 in Tan and Carney ~2003! did include LP2; the effects of its inclusion are illustrated here in Fig. 3.
