PASSENGER SHIP VIBRATION AND NOISE: PREDICTION, PREVENTION AND CURE

Noise and vibrations have so many features in common that they are frequently linked when referring to reduced comfort problems in accommodation spaces. They differ in the main frequency ranges of interest, although there is some overlap in the way in which they are measured and assessed and in their effect on human comfort and on machinery reliability. The impact of noise and vibration on the living quarters is termed 'habitability' in this paper unless specific reference is made to one or the other of these phenomena. Because of the importance of passenger comfort, the design techniques necessary to prevent excessive noise and vibration are subject to continuing theoretical and practical developments. A brief overview of the subject matter is therefore presented, after which the paper describes typical noise and vibration prediction techniques and some steps that can be taken to avoid problems at the design stage, during construction and in the event of problems developing during trial or in service.
