Two objective measures of human cochlear tuning, using stimulus-frequency otoacoustic
emissions (SFOAE), have been proposed. One measure used SFOAE phase-gradient delay
and the other two-tone suppression (2TS) tuning curves. Here, it is hypothesized that the two
measures lead to different frequency functions in the same listener. Two experiments were
conducted in ten young adult normal-hearing listeners in three frequency bands (1-2 kHz, 3-
4 kHz and 5-6 kHz). Experiment 1 recorded SFOAE latency as a function of stimulus …
