FIG. 8.

(Color online) Microstructure depth vs $T_{\text{sf}}^{\mathrm{S}}$ magnitude (for an L_p of 0 dB SL) for all maximum-minimum pairs observed between 1 and 4 kHz for one subject. The different distributions of data for maxima falling below and above 2 kHz (triangles and diamonds, respectively) suggest that the relationship between depth and $\left|T_{\text{sf}}^{\mathrm{S}}\right|$ varies with frequency, perhaps due to differences in $R_{\mathrm{b}}$ and $G_{\text{me}}^{\text{RT}}$. Symbols marked with vertical lines indicate data for maxima associated with SOAEs greater than −10 dB SPL in amplitude. The data and theoretical curves from Fig. 7(B) (gray circles/curves) are shown for comparison. Dashed vertical line indicates where $\left|R_{\mathrm{a}}\right|=1$.
