FIG. 3.

(Color online) SFOAE transfer function ($T_{\text{sf}}$) magnitudes for each subject in Fig. 2, illustrating the similarity of the SFOAE amplitude microstructures across L_p. SFOAE amplitude growth was near-linear at many frequencies, as evidenced by constant $T_{\text{sf}}$ magnitude across L_p. However, growth was sometimes more compressive near amplitude peaks, particularly those associated with SOAEs (black triangles), such that $T_{\text{sf}}$ magnitudes decreased with increasing L_p at these frequencies. Thin dashed portions of each curve indicate data with SNR < 6 dB.
