High pressure hose having tuning cables, called Resonator hose is frequently used to attenuate pressure ripple generated by the pump for reducing the vehicle interior noise. A number of studios have been conducted on the resonator hose and its analytical models. However, there are few studies which deal with the influence of resonator hose on vehicle interior noise because the most of studies were focused on transmission loss of the resonator hose. This paper presents NVH test results of power steering system and frequency analysis results. In the frequency analysis, both the relations between vibration, pressure ripple and vehicle interior noise and also the design parameters of high pressure hose influencing on vehicle Interior noise were discussed. The test was done for various high pressure hose specimens in full turn condition.
