Noise emissions from various transportation modes became in recent years a major concern for environmental and governmental agencies due to their impact on the community.

Abstract

Noise emissions from various transportation modes became in recent years a major concern for environmental and governmental agencies due to their impact on the community. As a result, experimental campaigns and studies have been directed towards the analysis and control of the main noise sources. Only a few analyses, however, have regarded noise exposure due to port activities. In this paper, the focus is on airborne noise emissions from a ferry ship. At first, the main onboard noise sources were identified in terms of their nature and location. Secondly, sources data on the main sources were derived, based on onboard measurements of the ferry berthed in the port of Naples. A geometrical 3D model was created, including all bodies present in the acoustic field of the surrounding area. Finally, by post processing, the consistency between actual acoustic field and numerical model results was checked.
