[Oscillations of the internal ear basilar membrane in the sonic and ultrasonic range from the data of mathematical analysis of the hydrodynamic model of the cochlea].
Results are presented of plotting a dimeric mathematical model of human internal ear cochlea with allowance for the dependence of the basilar membrane mass on the length of its region between the registered point and the labyrinth wall of the threshold window region. Investigations carried out on such a model by means of a computer permitted calculation of the location of the rounding curve maximum point of the displacement waves of the basilar membrane for the frequencies of 0.05-95 kHz included. An analysis of the rounding waves of the sonic and ultrasonic range showed that although above 20 kHz the curves maximum acquires slured contours, it is well enough pronounced up to 75 kHz. The results obtained suggest adequate effect of ultrasounds on the internal ear and analogy of mechanical reaction of human cochlea to sonic and ultrasonic stimulation.
