The growing requirements as to the permissible normative values of noise generated by machines stimulate the development of methods of reducing noise emission. One of the sources of noise in hydraulic systems are sound vibrations caused by pressure ripple. The article presents a method of reducing pressure ripple for a selected frequency by means of a passive chamber damper in a hydraulic micro power unit. The paper presents research on the location of the noise source with the frequency of pressure ripple, based on the Spatial Transformation of Sound Fields (STSF) algorithm.
