N2 - In the presented paper a numerical method for aerodynamic noise assessment on the basis of unsteady mean flow field data has been presented. This method belongs to the very wide family of so called hybrid CFD/CAA methods. In described method for calculations of the acoustic fluctuations a solution of full non-linear Euler equations is used. The Euler equations are solved with the use of numerical scheme with third order accuracy in space and time. The presented method is numerically decoupled with CFD solution, so that the information about mean unsteady flow field can be obtained using arbitrary CFD method (solver). The accuracy of the acoustic field assessment depends on the quality of the CFD solutions.
