PROBLEM TO BE SOLVED: To provide an injection noise reducing device of a turbine engine. SOLUTION: The injection noise reducing device 12 is provided for the turbine engine. The turbine engine has major axis X - X, and includes a substantially cylindrical nozzle 10. The nozzle is extended along the major axis of the turbine engine, and the nozzle has a downstream end for mixing inner and outer gas fluxes. The device 12 includes: two or more corrugated parts disposed in the extended part of the downstream end of the nozzle; and two or more cutout parts disposed between the consecutive corrugated parts of two or more corrugated parts. The two or more corrugated parts and the two or more cutout parts are asymmetrical about at least one axis Y - Y vertical to the major axis X - X of the turbine engine to produce counter-rotating effect between the gas fluxes.
