FIELD: nondestructive test. SUBSTANCE: method consists in processing of acoustic signal radiated by aerosol flux for determination of solid phase concentrations and classification of particles in flux. Signal is processed by transformation of summary signal into Fourier spectrum. Solid particle concentration is found by the first and timbre harmonics which have comb structure. EFFECT: higher test results. 1 dwg, 1 tbl
