We have worked with government agencies, environmental firms, and other private and public sector clients to:

  • Prepare the noise and vibration sections of environmental impacts reports or statements (EIR/EIS) to meet the requirements of CEQA and NEPA
  • Determine compliance with ordinances or specific acoustical requirements established by local jurisdictions
  • Perform any number of measurements and analyses to quantify acoustical levels and/or locate an unknown source
  • Predict future noise levels using tried-and-true mathematical and empirical modeling techniques
  • Design and/or recommend appropriate mitigation measures to reduce noise and vibration to acceptable levels
  • Prepare noise elements and noise ordinances
