This paper deals with results of identification tests of acoustic field spectrum of underwater noise generated by ship in motion. The field is connected with acoustic activity of ship mechanisms and devices in operation. Vibration energy generated by the mechanisms and devices is transferred through ship structural elements to surrounding water where it propagates in the form of acoustic waves of a broad band of frequencies. In the publication results of identification tests of underwater noise generated by a ship in motion, are presented

The article presents results of research on the spectral structure of the acoustic field of underwater noise generated to the water medium by selected units moving in a shallow sea. The underwater acoustic field of these units is bound with the mechanical activity of mechanisms and devices mounted in the vessel’s hull. The vibration energy originated by these mechanisms and devices is transmitted by the vessel’s construction elements to the water medium where it propagates in the form of acoustic waves in a wide frequency range. The work also presents results of identification and simulation of wave propagation included in the continuous spectrum of underwater noise.

This paper presents results of research on spectral structure of underwater noise acoustic field radiated into water by selected ships moving in shallow waters. Underwater acoustic field of ships in motion is associated with acoustic activity of ship mechanisms and equipment under work. Vibration energy radiated by the mechanisms and devices is transmitted by ship structural elements to surrounding water where it is propagated in the form of acoustic waves of a wide frequency band. In this paper are presented results of the research on propagation of energy of acoustic waves in the near fiel, obtained from acoustic pressure measurements by means of two sensors located close to each other

Measurements of hydro-acoustic noise emitted from vessels are a.o. a subject of the tests carried out in the control measurement ranges of the Navy. The measurements are performed both on anchored and floating vessels. Acoustic field of vessels is changing along with their speed changing and is associatedwith acoustic activity of wave sources installed in vessel’s hull (main engines, electric generating sets, reduction gears, pumps, shaft-lines, piping, ventilating ducts etc) as well as hydro-dynamic sources such as screw propellers and water flow around the hull [5, 7]. Vibration energy generated by the onboard devicesis transferred through ship structural elements to water where it propagates in the form of hydro-acoustic waves of a wide frequency band
