This paper has analyzed the relationship of flow, pressure pulsation and noise in hydraulic system, and has inquired into generation and propagation of fluid noise in the system. It is suggested that a constraint equation should be added to an analysis of general theory of a filter. K-type and H-type filters are theoretically analyzed and tested. The results indicate that they are very effective on controlling pressure pulsation, and can also obviously restrain the noise.
