Ships and marine technology. Model test method for propeller cavitation noise evaluation in ship design - Source level estimation Ingestion-build-64721 BS EN 617 deals with1 Scope This document specifies a model test method for propeller cavitation noise evaluation in ship design. The procedure comprises reproduction of noise source, noise measurements, post processing and scaling. The target noise source is propeller cavitation. Thus, this document describes the test set up and conditions to reproduce the cavitation patterns of the ship based on the similarity laws between the model and the ship. The propeller noise is
