The influence of the shape of an acoustic signal acting 
on a jet on the aerodynamic characteristics of the jet is investigated 
based on an analysis of experimental data. It is shown that in the 
considered case of a nonharmonic acoustic signal the attenuation of 
mixing in high-frequency acoustic excitation turns out to be more 
substantial than in harmonic excitation.
