FIELD: medicine, in particular, otolaryngology. SUBSTANCE: method involves detection of sound dispersion in front lymphatic chamber using anatomic and histological structures of inner ear and their physiological functions with respect to distribution of speed of sound across frequency range. Then method involves detection of standing waves at threshold diaphragm caused by interference of waves that travel about it and reflect from its free helicon edge. This is based on recurrent dependence between discreet sample values of experimental data. Then method involves detection of ratios for distribution of speed of sound and coordinates of basilar lamina across frequency range under condition of maximal mechanical force onto nerve knots of capillary cells which produce nerve impulses. Detected ratios correspond to frequency of source sound signal. EFFECT: increased precision of detection. 6 dwg
