Acoustic waves of high amplitude explore the nonlinearity of the medium they propagate in. Acousticians from all over the world discussed the special phenomena thereby brought about in gases, liquids, and solids. They range from shock waves, the rupture of liquids (cavitation), cleaning, cooling, light from sound and sound from light, to chemical synthesis, kidney stone destruction and hemostasis (stopping of bleeding by sound). Topics inluded are: nonlinear wave propagation, wave scattering and interaction, resonators and waveguides, sound beams, sound sources and focusing, thermoacoustics and streaming, waves in solids, microstructured and damaged materials, granular media, metrology, nondestructive testing and evaluation, cavitation bubble dynamics, optic cavitation and aspherical bubble collapse, single bubble sonoluminescence, multi-bubble cavitation and sonoluminescence, sonochemistry, biomedical applications, wave propagation in bubbly liquids.
