The present study has been performed by the University of Trieste within the BESST European Project with the aim to design an operational procedure for predicting ship’s outdoor noise in harbour. Procedure is here outlined in all its steps from the pre- to the post-processing phase and its effectiveness is proved. Method is implemented by application to a comprehensive case study. Numerical simulations are performed by exploiting a selected commercial software suited for acoustic mapping on noise emission in open field conditions. Results are then discussed with the aim to check operational procedure and computational tool. Basing on the same results, suggestions on the proper technique to approach the topical subject of ship’s outdoor noise in harbour are given. Paper starts with an introduction covering the matter of ship’s noise pollution in harbour and how it is today managed.
