Models of a direct-flow and counter-flow hydrodynamic radiator as a cylindrical environment with various boundary conditions are considered. The task of the compelled fluctuations of these dynamic systems
consider revising. The received expressions for amplitude-frequency characteristics of jet environments are compared to experimentally measured spectra of a generated sound. The analysis has shown, that the spectrum of a generated acoustic signal is identical to the amplitude-frequency characteristic of the flooded jet environment. On a theoretical spectrum, time functions of a signal have been received and their comparison with experimental soundtracks is carried out. Dependence of a spectrum of an acoustic signal on geometrical parameters of a jet environment and hydrostatic pressure in a liquid is analyzed. The submitted model allows to expect spectral charac
teristics of the sound generated by axially symmetric hydrodynamic radiators.
