Abstract (english): 
The present article deals with the prediction of the underwater noise induced by ship propellers under consideration of sheet cavitation on the propeller blades. The calculation method is a hybrid approach combining a boundary element calculation method with the Ffowcs-Williams Hawkings equation. The method is applied to different simulation cases with increasing complexity. The final case considers the noise propagation in full-scale for a cavitating propeller in combination with a part of a ship stern. This simulation result is compared to a full-scale measurement.
