Results of experimental investigation of turbulent mixing 
in jets flowing out of nozzles with different cross sections in the 
case of low- and high-frequency acoustic excitation of the jets are 
presented. The influence of the shape of the cross section of a nozzle 
on the acoustic-excitation sensitivity of a jet flowing out of it 
is analyzed.
