Mean values of f _tip shift/L _tip and f _tip-shift/L _tip difference for SFOAE STCs and PTCs. Mean values of f _tip shift and f _tip shift difference (a, b) and L _tip and L _tip difference (c, d) for SFOAE STCs and PTCs as a function of f _p at the L _ps of 30 dB SPL (dotted lines) and 50 dB SPL (solid lines). Red lines: SFOAE STCs; blue lines: PTCs. Error bars denote ±1 SD
