An experimental research on the noise energy radiated from ship partitions

Abstract

The paper presents an application of the sound intensity (SI) technique to assessing the effects of ship vibrations on the noise energy radiated by ship partitions. Example measurement results are given to illustrate the application of the SI technique to practical problems of the noise abatement on ships. The results are shown in the form of a two and three-dimensional flow map of active intensity vectors, graphically interpreted for the heterogeneous cabin partitions. The measurement technique as well as the way of graphical presentation can enrich the knowledge of the mechanism of acoustic energy flow through the real ship partitions.
