High-frequency distortion depends on center-tone phase. a The amplitude of the 2f3-f2 distortion product depends on the phase of the center tone. Similar findings were evident in both basilar membrane (BM; n = 7; blue) vibrations and organ of Corti (OoC; n = 3; red) potentials. b Corresponding data for the 3f1-2f2 distortion product. c Smaller effects of center tone phase were evident at 2f1-f2. d Data from a single animal with successful recording of high-frequency distortion at 44 dB SPL. In panel a–c, vertical bars denote the sem, and the lines are drawn through the mean values. Dots denote individual data points
