SHIPPING NOISE EVALUATION IN COASTAL WATERS

Objective

The final aim of the SNECOW project is the prediction of the noise intensity at the site of an underwater acoustic sensors array, in order to design an optimal acoustic underwater communication system. The most important contribution to the underwater noise level is due to the noise generated by the ship traffic.
The scientific approach to practical application for the estimation of underwater acoustic ship traffic noise has been adopted. The rationale of the project can be outlined as follows: definition and identification of source parameters; single and multiple ship traffic mathematical modelling identification; acoustic radiation and propagation modelling; signal and noise processing characterization with gaussian and nongaussian hypotheses; recognition and classification of ship acoustic emissions.
The project will be developed in several parts:
- study and characterisation of the source of the noise and the radiation mechanism in the surroundings of a set of transiting ships;
- the propagation of such a noise in the environment of coastal waters, by using propagation models;
- statistical characterisation of the shipping noise;
- the modelling of ship traffic, which represents a sort of sparse moving multi-element acoustic source in space-time;
- possible applications of artificial intelligence techniques to underwater acoustic sensors' integration.
