Abstract
Results of research of the acoustic field are analyzed, which is generated by a flooded (going in the environment) supersonic jet. It is shown that the basic source of a sound is located at a height of 230–260 mm from the nozzle, frequency of the basic harmonic makes 6 kHz. The ratio of amplitudes of harmonics depends on conditions of generation and the distance from nozzle. The field of a sound wave is non-uniform in the space around the jet axis.
