Abstract:

Between May 26 and June 4 in Moscow was held the Fourth All Union Acoustic Conference. The conference was frequented by about 1000 delegates, including from Leningrad, Kiev, Lvov, Gorki, Permi, Tashkent and other cities of the Soviet Union. There were also acoustic-specialists from China, Poland, Czechoslovakia, Hungary, Rumania, German Democratic Republic, Dunmark, and USA. About 180 reports on various subjects were read, which indicates the considerable rise in the number of investigations on acoustics and the greater interest in the achievements of this science by scientific and industrial institutions of the USSR. In the section of sound propagation in heterogeneous media, very interesting was the series of reports devoted to radiation methods of determining the field intensity and to the propagation in waveguides, particularly with irregular heterogeneities. At the meetings of nonlinear acoustics, reports pertaining to the solution of problems regarding propagation of waves of finite amplitude, as well as problems of sound formation were presented. Lectures on noise generation by intersecting gaseous streams and about noise emitted by an electric discharge in a liquid were given, etc. Author
