FIELD: apiculture. SUBSTANCE: method involves providing frequency filtering of reference analog signal and separating the most informative frequency range, for instance 100-600 Hz; discretizing the signal and selecting 3-5 short-time realizations of 0.5-1.0 s duration satisfying the requirement of minor deviation differences; on the basis of one of them, calculating energetic spectrum of realizations of discrete signal by acoustic noise emitted by fee family; dividing energetic spectrum into 10-12 frequency bands; calculating spectral density mean values for frequency bands and determining bee family state by comparative analysis of spectral density mean values of these frequency bands for diagnosed bee family state. EFFECT: increased efficiency and simplified method. 3 dwg, 1 ex
