HYDROACOUSTIC NOISE MEASUREMENTS

The paper deals mainly with investigation of underwater noise that propagation is in shallow water. In this paper has been presented the experimental investigation results concerning the distribution of the sound field pressure generated by moving ships in the shallow water at the small distance from the ship. The main acoustical characteristics describing features of the field are spectrograms in pseudo 3D system – distance and frequency and sound intensity. Results pointed individual features of ship are known often as an acoustical signature of the ship. The two main sources of the ship will be taken into account. Vibration energy generated by the mechanisms is transferred through structural elements to surrounding water where it propagates in the form of acoustic waves of broadband frequencies. Also the noise generated by the ship propeller will be matter of interest.
