Environmental Noise

Lewis S. Goodfriend & Associates provides services to measure noise and vibration levels and provide recommendations for noise control. LSG&A’s environmental noise experience includes preparing the acoustical sections of environmental impact statements, community noise surveys, and field monitoring for existing or proposed land uses. Our services also include designing sound barrier walls to reduce community noise levels due to transportation noise sources including automobiles, trucks, buses, and transit vehicles. Our experience includes assisting governmental agencies in drafting noise ordinances and regulations. Our clients include developers, architects, engineers, pharmaceutical companies, and local and state agencies.

 

BMW of North America: Woodridge, New Jersey
SJP Properties

  • Completed an evaluation of the expected property line sound pressure levels due to the operation of the existing mechanical equipment, and proposed emergency generators, exhaust fans, rooftop air-handling units, and chiller planned for installation at the BMW Campus.

 


Digital Realty Trust Data Center: Philadelphia, Pennsylvania
Busch Associates

  • Evaluated the acoustical feasibility of installing numerous generators and condensing units on the building roof, based upon the limits of the City of Philadelphia’s noise regulation.
  • Developed an acoustical model of the proposed rooftop equipment to determine the expected sound level at the nearest receiver.

 

 


New York Society Library: New York, New York
New York Society Library

  • Completed sound pressure level measurements on the rooftop of The New York Society Library to determine the sound levels due to noise emanating from the cooling tower servicing the library.
  • Provided the preliminary results of the evaluation, including the measured sound pressure levels with and without the existing cooling tower operating, a specification for the proposed cooling tower, and a comparison with the applicable sections of the New York City Noise Regulation.

 


Verizon Cellular Station Noise Evaluation: Fairfield, New Jersey
Tetra Tech EM

  • Completed an evaluation of the expected sound pressure levels due to the operation of the new Verizon Wireless equipment proposed to be installed at the Fairfield IV wireless communications facility.
  • Evaluated the expected sound pressure levels along the nearest neighboring residential and commercial property lines with the proposed units operating, and a comparison of the expected sound pressure levels with the applicable noise regulation.

 


Prudential Building: Newark, New Jersey
The Prudential Insurance Co. of America

  • Completed an evaluation of the sound pressure levels in the office adjacent to the existing mechanical equipment operations at the Prudential Building.
  • Provided the results of the evaluation, including the existing sound pressure levels inside the adjacent office space, and a comparison of the expected sound pressure levels with the existing ambient sound pressure levels inside the adjacent office space, and compared with the preferred Noise Criterion (NC) ratings for office spaces.

 


Bridgewater Resources, Inc. Waste Transfer Station: Bridgewater, New Jersey
Kenneth L. Woodruff & Associates

  • Performed sound pressure measurements at the nearest property line during normal daytime operations and early morning non-operational hours.
  • Evaluated and compared these measurements to the New Jersey Department of Environmental Protection (NJEDP) noise regulation.
  • The purpose of these measurements was to document sound pressure levels of the facility during normal hours and evaluate compliance with the limits of State and local regulations due to the facility’s proposed expanded hours of operation.
