Challenges and Limitations in Retrofitting Facilities for Low Frequency Noise

Paul Wierzba, Ph.D., P. Eng

Abstract
Equipment associated with Oil & Gas facilities emits high levels of low frequency noise. As these facilities become more and more distributed, their proximity to the residential areas increases, and so do their noise contribution levels. The low frequency noise is gradually being recognized as one of the main issues negatively affecting the relationship between the energy facilities and neighboring communities. Excessive levels of low frequency noise can have a significant impact at the residential locations ranging from annoyance to sleep deprivation. Generally, there is little awareness in the energy industry in regard to low frequency noise and its effect on communities. Frequently, insufficient attention is paid to low frequency noise during the facility design stage. This often leads to costly retrofits. This paper discusses the challenges and limitations of field retrofits of the facilities aimed at reducing low frequency noise on the basis of actual field cases.
