Inboard noise and underwater radiated noise are becomingmore and more important factors during the designof ships. Model tests are often used to support the designprocess of ships, but noise measurements are notoften included in the model test campaign. However,with a growing concern regarding the effect of underwaterradiated noise on marine life, and the demand forlower inboard noise, the need for accurate noise predictiontools, such as model tests, is increasing.The test setup for conducting noise measurements inMARIN's Depressurized Wave Basin is presented aswell as the procedure for such model tests. The scalingprocedure of the model-scale results to full scale isdiscussed. The results of model tests for a high-comfortclass cruise ferry using these procedures are presented,followed by a discussion of the design issues of such aship.
