Abstract : Research on nonlinear acoustics has been performed during the 12-month period ending 30 September 1994. Progress is reported on the following projects: (1) Production of an isolated negative pulse in water (experimental); (2) Self-refraction in the field of a paraboloidal reflector (experimental); (3) Preliminary study of the acoustitron (theoretical). Public communication of the research includes one thesis, two oral papers, two journal articles published, three journal articles submitted, and one book chapter submitted.
