摘要：
A numerical model was developed for a floating floor with an inserted viscoelastic layer to predict the structure-borne noise (SBN) in ship cabins. In cabins, high-density mineral wool is usually used as an impact-absorbing material. The theoretical model consisted of multipanel structures lined with high-density mineral wool. The predicted results for SBN when a floating floor with an inserted viscoelastic layer is used were compared with the measurements done on a cabin mock-up. Various floating floors with inserted viscoelastic layer structures were studied, and the effects of variations in the thickness, density, and fiber direction of the high-density mineral wool were investigated. Comparisons of the predicted results and the experimental results showed that the developed model could be an effective tool for predicting SBN in ship cabins.
