Аннотация: Many real liquids contain solid inclusions of various sizes in addition to the liquid phase itself. These inclusions influence the propagation of acoustic waves. Such acoustic wave parameters as absorption and speed of sound propagation depend on the size and concentration of particles. For some multicomponent systems, acoustic parПоказать полностьюameters can be described quite well using Urick's proposed theory. In this study, the dependences of the absorption coefficient and speed of sound are obtained for an agarose gel suspension with talc particles and for suspensions with silica particles. Experimental attenuation spectra in different suspensions were compared with theoretical calculations of the Urick model. The dependences of acoustic absorption and speed of sound on concentration in suspensions with different particle sizes were obtained. The comparison results showed that the Urick model satisfactorily describes the absorption in various suspensions at particle concentrations φ < 20%.
