This paper reviews the considerable progress that has been made over the last 25 years in the understanding of noise inhydraulic systems. Sources of fluid borne noise, structure borne noise and the resultant airborne are discussed in detailand methods of measuring, analysing and predicting behaviour are presented. This leads on to a discussion ofcomponent and system design issues. The paper concludes by identifying areas where further work is required.
