The results of experimental investigation of the influence 
of high-frequency (low-frequency) acoustic action on a turbulent jet 
preexcited by sound of low (high) frequency are presented. It is shown 
that the qualitative character of the action remains the same as that 
for an unexcited jet. However, the quantitative results here are somewhat 
different; in particular, the possibilities of suppressing turbulence 
in the jet in its high-frequency excitation are reduced in this case.
