Comparison of inferred slopes of the cochlear nonlinearity: Subject 2A versus animals. The inferred slopes of the cochlear nonlinearity for Subject 2A 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 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 2A. Rightward shifts, in decibels, were applied to the physiological curves or plots, as described in the caption to Figure 17.
