Nonlinear acoustics and its applications are one of the areas of research conducted at LIMU. In this direction, our laboratory does a lot together with colleagues from different countries. Some time ago, Oleg Sapozhnikov received an invitation from the editor of the science magazine “Acoustics Today”, published by the American Acoustic Society, to write an article on modern nonlinear acoustics. Such a brief review entitled “Nonlinear Acoustics Today” was eventually written jointly with Vera Khokhlova and colleagues from the United States (Mark Hamilton), England (Robin Cleveland), and France (Philippe Blanc-Benon).
