Abstract

The article presents the application of the sound intensity technique to the graphical presentation of the spatial distribution of the intensity field radiated by the part of cabins wall with windows. For the region of a window box there is illustrated a two-dimensional flow map of the time-averaged active intensity space vector as a projection onto the measured ,,xy" plane and a vector ,,z" perpendicular to the measured plane. Additionally, the distribution of the acoustic energy streamlines is presented. The analysis of an acoustic field shape produced near the windows of a ship's cabin before and after installing the shipboard wall makes it possible to estimate local radiation sources and regions of vibro-acoustic bridges through which the energy is passed over to the shipboard wall of the
