Abstract:

Research on nonlinear acoustics has been carded out during the 12- month period ending 30 September 1992. Progress is reported on the following projects 1 Propagation in a periodic waveguide 2 Scattering of sound by sound 3 Finite-amplitude waves in a three-layer fluid 4 Finite-amplitude waves in a medium having a distribution of relaxation processes and, 5 Propagation of an isolated negative-pressure pulse in water....
