The present book is a unique text and reference on the theory and applications of nonlinear acoustics. Individual chapters are written by leading experts on their respective subjects. The book combines the merits of a graduate textbook format with the scholarly appeal of a research monograph for physicists and engineers. The first half of the book develops physical concepts, mathematical models, and classical methods of solution. Benchmark experiments are also described. The second half covers special topics and applications, both theory and experiment. Applications include methods for determining the nonlinearity parameter; suppression of sound by sound; acoustic levitation and streaming; sound beams and parametric arrays; statistical phenomena; four-wave mixing; phase conjugation; biomedical effects; propagation in the atmosphere, ocean, waveguides, relaxing fluids, and bubbly liquids.
