The large range of applications of acoustical methods and techniques in the modern society demands a thorough exploration of the nonlinear properties of sound-wave propagation in different media and environments, and effects caused by nonlinear interaction of sound and medium. The great range of interesting physical phenomena which occurs in nonlinear acoustics stimulates research worldwide, with non-diminishing activity.
