FIELD: medicine, diagnostics. ^ SUBSTANCE: the suggested method deals with stimulation of tympanic membrane fluctuations due to the action of sound impact with possibility to alter not the intensity only, but the frequency of sound impact, also, followed by irradiation of tympanic membrane with laser radiation, direction of reflected radiation into laser resonator, registration of altered power of laser radiation as electric signal, division of registered signal into spectral constituents, alteration in the intensity of sound impact till the stoppage of amplitude growth of spectral component having maximum value, the calculation of fluctuation amplitude of tympanic membrane xialt due to applying the obtained spectral constituents of the signal. The innovation provides higher sensitivity of performed measurements at providing the chance to carry out measurements in vivo. ^ EFFECT: higher accuracy of measurement. ^ 5 dwg |
