Satisfactory control of fluid power system noise is dependent upon accurate knowledge of component noise levels. One component which contributes to the total system noise level is the hydraulic pump. There are test methods available for measuring and reporting airborne pump noise. However, these test methods need to be carefully examined to insure that proper constraints are placed on the various hydraulic and mechanical factors which affect the accurate measurement of pump airborne noise.This paper describes the major hydraulic and mechanical factors that affect the measurement of pump airborne noise. Experimental data are presented to illustrate the variation that can result due to such factors as the pump mount, fluid lines, and the drive shaft. Techniques for reducing the variation due to these factors are presented for the reader's consideration.
