Some basic concepts involved in the ship acoustics are reported in the lesson. The main noise sources on board are briefly overviewed as well as the typical transmission paths along which noise can be transmitted to a receiving position. The peculiarities of the ship context with respect to other industrial environments are outlined. Some problems connected with the characterization of the various sources strength are presented. The basic concepts of noise reduction (absorption, damping, isolation) are overviewed together with some quantities commonly used to describe the effectiveness of different counter-measures adooted on board.

Abstract
Some basic concepts involved in the ship acoustics are reported in the lesson. The main noise sources on board are briefly overviewed as well as the typical transmission paths along which noise can be transmitted to a receiving position. The peculiarities of the ship context with respect to other industrial environments are outlined. Some problems connected with the characterization of the various sources strength are presented. The basic concepts of noise reduction (absorption, damping, isolation) are overviewed together with some quantities commonly used to describe the effectiveness of different counter-measures adooted on board.
