FIG. 5.

Individual (thin gray lines) and average (thick black line) CAS-mediated changes in thresholds for all twelve SOAE-specific measurements. In A, threshold changes were calculated at frequencies relative to the SOAE frequency in quiet, thus preserving the effects of the frequency shift in the fine structure patterns (as in Fig. 3). In B, changes were calculated after first aligning the threshold curves with respect to their minima, i.e., by plotting thresholds as a function of frequency distance from the SOAE in the same condition (as in Fig. 4).
