These guidelines describe a method for in-situ determination of the sound power level of the noise sources in indoor or outdoor environments for gas compressor station equipment using sound intensity measurements. The guidelines contain information…
The initial objective of this program was to define noise effects and criteria both for employee hearing protection and prevention of community noise intrusion, and thereafter turned to the development of analytical and engineering techniques to…
Covers research involving noise model requirements and evaluation of a number of existing models for applicability to pipeline compressor station conditions. Leads to development of improvements to existing AGASUM model. Resulting model, AGASOUND, is…
This report is divided into two parts. Part A contains field test procedures and measurement and analysis techniques for compressor station noise. The results of a field test program conducted at nine mainline compressor stations are also included.…
The first section of this report contains techniques for designing silencers to suppress the noise produced during high pressure gas blow-offs. Both complex analytical techniques and simplified design charts are presented
The five sections of this report focus on defining the nature of noise emitted from pipe carrying high-velocity flow and prescribing methods for suppression or elimination of such noise. The contents of each section are as follows:Section I - sources…
In an effort to better understand the detrimental effects of noise on worker productivity and general well-being, this report presents data gathered in the following three areas: (1) physiological and psychological effects of sound on man
Increasing legislation and public awareness of noise are intensifying the efforts of industries today to reduce the noise. The natural gas industry has proved that it is one of the industrial leaders in its awareness of noise problems and has…
Noise levels radiated from the exterior of a pipe wall can significantly contribute to the overall noise levels on the site of a gas plant and at neighboring properties. The noise inside the piping is generated both by the gas compressor itself, and…
