Comparison of inferred slopes of the cochlear nonlinearity: Subject 1A versus animals. The inferred slopes of the cochlear nonlinearity for Subject 1A (continuous curves, same as the broken curves from the upper panel of Figure 16) are overlaid upon dashed curves (Eq. 12 for upper panel, Eq. 14 for middle panel) or data (for lower panel) for the nonlinearity slopes from Guinea pigs or from chinchillas. The solid curves here are the same in the upper, middle, and lower panels, and represent different values of the unknown proportionality constant K for Subject 1A. Rightward shifts, in decibels, were applied to the physiologically-derived curves or plots (see text); those shifts, and their allowed ranges in decibels are as follows: (upper panel) CF=17.7 kHz, shift=15.54 dB, allowed range={9.47,22.48}; CF=18 kHz, shift=18.54 dB, allowed range={9.54, 22.55}; CF=19.5 kHz, shift=13.54 dB, allowed range={9.89, 22.90}; (middle panel) CF=5.5 kHz, shift=15.54 dB, allowed range={4.39, 17.40}; CF=7.25 kHz, shift=19.54 dB, allowed range={5.59, 18.60}; CF=9.75 kHz, shift=14.54 dB, allowed range={6.88, 19.89}; CF=14 kHz, shift=11.54 dB, allowed range={8.45, 21.46}; (lower panel) CF=9 kHz, shift=10 dB, allowed range={6.53, 19.54}; CF=8 kHz, shift=13 dB, allowed range={6.02, 19.03}; CF=10 kHz, shift=12 dB, allowed range={6.99,20}; CF=9 kHz, shift=8 dB, range={6.53, 19.54}.
