Behavioral pure-tone hearing thresholds and stimulus-frequency otoacoustic emissions (SFOAEs) were measured with a high frequency resolution from 0.5-20 kHz in 15 female participants. Stimuli were calibrated in terms of forward pressure level (FPL). SFOAE responses to 36 dB FPL probes were largest near 1 kHz and declined above 8-10 kHz, though were still measurable at frequencies approaching 16 kHz in some ears. SFOAEs typically dropped in amplitude at a frequency that was roughly one octave below the "corner" frequency of the audiogram, and one-third to one-half of an octave below the frequency where thresholds departed from highly sensitive hearing. High-frequency SFOAE responses are likely limited by a reduction in the efficiency of the underlying generation mechanism and/or a diminished region of generation as the stimulus-driven excitation approaches the basal-most portion of the cochlea.
