RSI Noise analysis: Don’t let noise get you off on the wrong foot at your site. Sound assessment studies are becoming an important part of the pre and post construction process. They demonstrate compliance with regulations and ordinances. RSI has provides industrial hygiene and safety services to clients nationwide. RSI serves a wide variety of federal, state and commercial clients, the majority of which are repeat customers with multiple facilities. Our clients have come to rely upon RSI for a myriad of services.

Noise studies are often required for environmental assessments, Certificates of Public Convenience & Necessity, zoning compliance and other regulations. RSI noise experts have been identifying noise-sensitive areas for over 20 years. Having RSI document existing noise levels can help you avoid costly delays.

The RSI staff performs the appropriate level of noise analysis. Once individual sources have been identified, RSI can develop practical controls to abate the noise. Concept designs will be reviewed with management and maintenance personnel to develop a solution that will reduce the noise, minimize impact on maintenance, and minimize the cost. When the concept designs have been developed, a final report documenting existing noise levels and sources, recommendations, concept designs, material costs, and predicted noise levels after implementation will be submitted. Once noise abatement is implemented, RSI can measure the actual noise levels to verify the prediction in the final report.

Does your site have complaints?
If so the emphasis of this program is to provide the acoustical data necessary to define the existing conditions causing the complaints. In addition, the sources of the complaints will be identified and practical noise control solutions which will achieve the noise abatement required will be designed. The emphasis is also on developing solutions that will have a minimal effect on the normal operation and maintenance of the equipment being acoustically treated.

A typical project would begin with RSI conducting a noise survey at the Telcom facility. If located in a densely populated urban area. Sound pressure levels would be measured in the neighboring community, both before and after installation of equipment, to evaluate compliance with the applicable noise regulations. Based on the noise survey results, if noise regulation limits were exceeded, noise abatement actions would be recommended to mitigate excessive noise levels at the adjacent residences. The recommendations would be made most effective noise abatement actions. With this valid information RSI finds and corrects the problem.

All measurements are taken in accordance with accepted methodologies such as ISO or ASTM, using Type I/II integrating sound level meters. Evaluations are made in reference to community planning standards such as local noise control ordinances, the California Model Community Noise Control Ordinance, and are based on accepted CNEL/Ldn measurement methodology.

Qualifications of the Persons Performing Noise Evaluations
It is essential that those individuals performing measurements and analyses associated with the evaluation of construction noise possess the basic knowledge of the noise measurement techniques and prediction methodologies employed. Also essential is an understanding of the input data requirements and their sensitivities. A general knowledge of construction operations typical of the specific project being evaluated is also required. RSI knows Telcom, Construction, Oil & Gas and Wind turbines farms.
