Analytical and numerical solutions of a nonlinear acoustical equation of a relaxing medium are considired. The full classification of the stationary structures described by this equation is given.
Keywords: shock wave, stationary structure, self-sustained wave, stability, nonequilibrium medium, relaxation, sound amplification, negative dispersion, negative viscosity.
