Guidelines for sound power level measurements for compressor station equipment. Final report
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 on instrumentation, installation and operation of the source, procedures for the selection of a measurement surface, procedures for the sampling of sound intensity on the measurement surface, procedures for the calculation of sound power level, and techniques that can be used to qualify the measurement environment. Typical results obtained for different types of equipment in a gas compressor station using these guidelines are summarized. Appendix A gives procedures to calculate A-weighted sound power level from octave or one-third octave band sound power levels. Appendix B gives descriptions about data quality indicators which are useful in making validity judgments for the sound power measurements. Appendix C describes sound power measurements using the sound pressure method. Appendix D describes sound power measurements at low frequency. Appendix E gives descriptions about sound power measurements on exhaust stacks with air flow. The Addendum to this report includes examples of the application of the guideline document to real field sound power measurements and examples of calculations of data quality indicators. It serves as a convenient and quick reference document with procedures and examples which are easy to follow in real field sound power measurement problems. Readers of the Addendum are assumed to be familiar with the detailed descriptions of the sound power measurement procedures contained in the main guideline document.
