The parameters of the acoustic jet arising at the open end of a waveguide in which an intense harmonic sound field sets in in the form of a standing wave at the waveguide resonant frequency are experimentally studied. Earlier developed methods of recording and analyzing the velocity field are used. The spatial development of the jet near the waveguide open end at resonant frequencies 175 and 358 Hz and sound pressure 160 dB in the incident wave is studied. The jet velocity and its oscillatory component are quantitatively estimated.
