Gradually increasing magnitudes of the nSFOAE response to brief tones presented at differing times following the onset of the 400-ms wideband noise. For efficiency, these data were collected in blocks of trials in which every stimulus presentation contained two tone delays, always separated by at least 195 ms. The tone was 4.0 kHz, 60 dB SPL in level, and 10 ms in duration, and the noise was 0.1 – 6.0 kHz wide, 25 dB spectrum level, and 400 ms in duration. Each subject’s data are shown in a separate panel; the four subjects at the top were the first crew of listeners tested. The dashed lines show the best-fitting positive exponential functions beginning 20 ms after noise onset (the hesitation). The weaker nSFOAE response for short delays than for long delays is reminiscent of the behavioral phenomenon of overshoot.
