Much of the mid- and high-frequency noise in process plants derives from the flow of fluids through valves, orifices, and other pipework-located discontinuities. The myriad of sources involved generates, within the plant, a sound field that is diffuse and uniform. In this paper the author develops a tentative parametric formulation by which the generalized fluid pipe source can be described and also presents an analytical basis on which the in-plant and community environmental criteria can be related to the sound generating propensity of the individual source.
