This paper reviews research on vibration and noise in the open deck spaces of large cruise ships. In the first part, the main functions, features and vibration and noise source characteristics of typical leisure and entertainment areas in open deck spaces are analyzed and categorized. The second part outlines sub-model methods adapted to predict structural vibration caused by wind in open spaces, and the research progress of wind-induced vibration is introduced. An analysis is then made of the advantages and disadvantages of different prediction methods, including discrete methods (FEM/BEM/IEM), statistical energy analysis (SEA) and geometric acoustic method (i.e. ray tracing), in the two dimensions of noise frequency and acoustic field, and a hybrid method is recommended due to its good adaptability for noise prediction in open deck spaces, which provides the basis for the prediction process. Finally, a soundscape comfort-based design concept is proposed through an analysis of traditional noise evaluation and measurement methods, which can be used as a reference for vibration and noise control in the open deck spaces of large cruise ships.
