Location of Noise Sources in Fluid Power Machines

Fiebig W.

International Journal of Occupational Safety and Ergonomics

2007

Vol. 13, No. 4

441--450

This paper discusses noise generation mechanisms and techniques for noise reduction in fluid power units. Major noise sources in fluid power units can be identified with a sound intensity method. It has been proved that components of power units with larger sound radiating surfaces such as an electric motor and an oil reservoir produce a major part of global noise radiation.
