Abstract

In the last decade of the 20th century the continuous increasing of human activities in the ocean has focused the attention of local and international institutions on the underwater noise pollution due to shipping traffic. While for military purposes the topic of ship noise generation gained a fundamental role since the WWII, in the civil field only recently standards for ship noise measurements have been addressed and limits to the radiated noise have been developed in order to reduce the shipping impact on the marine fauna. In view of the enforcement of compulsory limits in the next future, the possibility of evaluating the ship noise spectrum at a preliminary design stage represents a significant topic. In this paper, with the aim of verifying the reliability of a selection of available empirical models for the ship radiated noise, a comparison of predictions with measured noise spectra for a small set of ships is carried out.
