Abstract
Method and apparatus for reduction of fluid borne noise in a hydraulic system are disclosed. The apparatus is an improved isolating hose assembly having first and second volumetrically compliant sections fluidly connected by an inductive flow member. Each of the first and second volumetrically compliant sections may, in addition, include a resistive flow element. The resistive flow elements are used to eliminate resonant conditions in the first and second volumetrically compliant sections at selected frequencies where capacitive behavior thereof would otherwise be compromised.
