From: The Human Cochlear Mechanical Nonlinearity Inferred via Psychometric Functions

Figure 16

The inferred slope f ¯ x of the cochlear nonlinearity, versus the intensity of the probe-tone. The solid lines show the inferences from Experiment 1, which used a fixed-intensity forward-masker and varied the masker-probe time-gap. The dashed lines show the inferences from Experiment 2, which used a fixed masker-probe time-gap and varied the forward-masker intensity. The dashed lines are not shown beyond 70 dB SPL because that is the approximate upper limit of good fit of the equations describing psychometric-function slope vs. probe-tone detection threshold in Experiment 2 (Figure 11). The labels show the various assumed values of the unknown proportionality constant K . The inferred slopes are shown for Subject 1 (Eqs. 6a, 6b; Experiment 1) and Subject 1A (Eq. 9; Experiment 2), who are actually the same person.
