The article presents the application of the sound intensity (SI) technique to the measurement of the acoustic radiation of ship cabin partitions. On the basis of the near field acoustic intensity measurement with the fixed point method, the distribution of spatial intensity vectors in a measurement plane is presented. As a result of the investigation, a three-dimensional flow map of active intensity vectors distributed in crow cabin is graphically illustrated in different forms. The measurement technique described, as well as the method of graphical presentation of results, can enrich the knowledge of the mechanism of acoustic energy flux inside small enclosures. There is also technique that can be powerful tool in noise abatement education.
