Abstract

Noise generation remains a key problem in current applications and in the expansion of fluid power systems to new applications. Understanding how to measure and characterize the airborne noise generated by displacement machines leads to a better understanding of how to improve the noise performance. A novel method of characterizing and interpreting the noise performance of displacement machines is explained and the significance of the results pertaining to the design of new quieter solutions is discussed
