Frequency spectra of the intracochlear pressure difference (ICPD) of TB3 for all measured modulation frequencies. The spectra cover frequencies from 10 Hz to 10 kHz. The frequency resolution of the spectrum is 1 Hz per data bin. Measured pressures at each particular modulation frequency were far above noise-level.
