The sound levels due to emergency generators, turbines, combined heat and power systems, and related equipment are evaluated with respect to noise regulations and project design goals. Baseline measurements are performed to document existing sound levels, and computer models are used to calculate the expected sound levels due to proposed equipment. LSG&A develops noise control recommendations for equipment to reduce the acoustical impact on the surrounding areas. We also provide expert testimony for applications before municipal boards to support and supplement our evaluations, and provide post-installation testing to verify compliance.
