Response characteristics of the model cochlear-partition transfer functions at the 1 kHz place at stimulus levels of 32–62 dB SPL (described in Fig. 13). Means and standard deviations (STDs) were calculated for 11 random-seed cases. The results were obtained with the optimal model parameters described in Table 6. Q3 dB and Q10 dB are “quality factors” measured at 3 and 10 dB points relative to the peak; QERB is a quality factor measured using the equivalent rectangular bandwidth (ERB). The quality factors are dimensionless. PSR stands for peak-to-shoulder ratio, also known as tip-to-tail ratio.
