Kurzfassung
The source localization method SODIX is able to determine the individual contributions of the engine components to the overall radiated noise. The method is now applied to new far-field measurements of a short-cowl engine. SODIX is used to evaluate the effect of an intake liner on the sound field radiated from the engine intake by comparing different engine configurations with and without the intake liner. The source localization results show that SODIX is able to quantify the effect of the intake liner even when the overall sound pressure levels are dominated by other sound sources like jet noise.
