Measurements of pump fluidborne noise can be influenced to a considerable degree by the effects of standing waves and volume compressibility within the discharge line. In the absence of a standard procedure for handling these effects, it is difficult to make comparisons of pump fluidborne noise data and to use such data in low noise system design. This paper discusses the influence of discharge line parameters on fluidborne noise measurements and proposes a simplified test procedure for determining the inherent fluidborne noise level of a pump. Results from experimental and analytical investigations are described.
