Abstract
The dispersion and dissipation of the acoustic signal in a multifraction gas suspension is investigated. A closed linearized system of differential equations of the perturbed motion of a multifraction gas suspension and the analytical dependence of the complex wave number on the perturbation frequency are presented. Using the fast Fourier transform method, calculations were performed on the propagation of pulsed perturbations in the considered media. The influence of the parameters of the dispersed phase on the dispersion and dissipation of the acoustic signal is analyzed.
