摘要：
Results of a theoretical study and numerical simulation of the propagation of longitudinal acoustic waves in a medium with bimodular nonlinearity and linear dissipation are presented. The exact analytical solutions are derived for stationary and self-similar waves. Numerical simulation of the propagation of initially harmonic waves was carried out using the spectral method.
