Experimental and theoretical research results on influence of a mutual tangential position of stators in stator-rotor-stator of the axial compressor on pressure pulsations and upwards radiated noise are presented. At equal number of vanes in stators their optimum mutual tangential position allows to lower twice pressure pulsations on rotor blades. It results in essential decrease both exciting loadings and radiated noise.
