The primary sources of ship noise observed on the bottom of sea

The paper presents the experimental research associated with the spatial distribution of acoustic energy generated by moving ship into the shallow water. Moreover, the paper present the methodology of determination of acoustics energy from the main mechanisms of ship into the water environment. For that purpose the research of noise spatial distribution of the ship were conducted along the hydroacoustic field. This research allowed to determine ship signature spatial distribution of chosen main mechanisms on the bottom of sea.
