Nonlinear acoustics is a branch of physics dealing with study of properties and utilization of high-amplitude acoustic fields. Amplitudes of these fields attain such values that the methods and procedures well-known from the linear acoustic cannot be used anymore for their description. Many nonlinear effects are connected with these fields. These effects offer great application potential (radiation pressure, acoustic streaming, cavitation, generation of heat, etc.) and on the other hand, they prevent effective increase of amplitude of these fields.
