In cruise ships, it is inevitable to arrange the cabins near by the noisy areas, such as ventilation fan, HVAC machinery and funnel casing etc. The noise is propagated to the cabins by way of mount, foundation and deck. The transmitted noise to cabin is affected by mount and foundation structure. It is well-known that most of the structure-borne noise can be reduced by the flexible mount. However, when the foundation of machinery is designed inappropriately, it can make noise problems in cabins. In this paper, the effect of foundation on noise reduction is studied through the numerical analysis and mock up test. The dynamic performance of foundation is investigated from the viewpoint of the impedance and noise reduction in cabin.
