This International Standard specifies a model test method for propeller cavitation noise evaluation in ship design. The procedure comprises of reproduction of noise source, noise measurements, post processing and scaling. The target noise source is propeller cavitation. Thus, the International Standard 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 to be measured at 3 stages. The measurement targets for each stage are propeller cavitation noise, background noise, and transmission loss. For the source level evaluations, corrections for the background noise and the transmission loss are applied to the measured propeller cavitation noise. Finally, the full scale source levels are to be estimated from the model scale results using a scaling law.
