[Microphonic cochlear potentials in the cat during exposure to 2-tons harmonic signals with different phase spectra].
Cochlear microphonic potentials (CM), i. e. the round window responses, evoked by the two-tone sound complexes consisting of the 1st and 2nd harmonics with different phase relation between the components were studied in cats. The spectral analysis of the CM responses showed high sensitivity of the CM potentials to phase changes in the complex sound stimuli. The 1st harmonic in the range of 350--750 Hz could be reduced at a certain phase shift of the 2nd harmonic in the complex signal. The phase and frequency limits of this phenomenon are described.
