Abstract
The noise occurring in ship's accommodation comes mainly from structural sounds, emitted by vibrating partitions. Ship's partitions, characterised by high constructional heterogeneity (partitions made of panels of sandwich structure, walls with windows and doors), are surfaces of heterogeneous distribution of vibrations, and the acoustic power radiated by such a surface source may be determined only experimentally. In this case a very useful tool in research is a sound intensity technique. One of the main advantages of sound intensity method, is the possibility to identify the structure borne noise energy transmitted through different parts of vibrating structure and give the very useful informa
