Profile: FDI Acoustics Inc. is an acoustical consulting firm specializing in facility noise measurement and sound reduction for the oil and gas industry. We provide environmental noise impact assessments and reports, noise monitoring surveys and noise control assessments & recommendations along with sound advice and delivery. Noise impact assessment is a technical report that presents the calculated existing or future noise impact of a facility on its environment. Comprehensive sound surveys are used to determine regulatory compliance. Comprehensive sound surveys are extremely weather dependent, and must be performed under the environmental and operational conditions in which a noise complaint has been registered. The duration of the survey and the placement of the sound monitoring equipment depend on the particular regulation in effect for the location assessed. After the monitoring data is collected, the review process begins, and sounds not associated with the facility being assessed are removed from the data set. The sound level that remains after the isolation process is complete is compared with the permissible sound level of the regulation. A technical report is then issued detailing the entire process and the survey results.
