Environmental Noise Measurements
Our team conducts precise environmental noise measurements using ANSI-certified equipment and calibrated instruments. We perform sound power level determinations, ambient noise surveys, and regulatory compliance measurements across diverse industrial settings. Our methodology follows international standards including ISO 6190 and ASTM E90, ensuring accurate data collection for regulatory submissions and mitigation planning.
Regulatory Compliance Assessments
We help clients navigate complex noise regulations at international, federal, and state levels. Our assessments interpret requirements from agencies like EPA, OSHA, and state environmental departments. We provide defensible compliance documentation and risk assessments, balancing regulatory requirements with project objectives through detailed analysis and clear reporting.
Noise Mitigation Design
Our mitigation solutions combine acoustical modeling with practical engineering. We design noise walls, berms, and equipment modifications tailored to specific projects. Our approach optimizes source placement and material selection to achieve compliance efficiently, using predictive modeling to test solutions before implementation for cost-effective results.
Expert Witness Testimony
Our consultants provide expert testimony in regulatory proceedings and legal cases. With experience in public service commissions and municipal courts, we present complex acoustical data through clear technical reports and courtroom presentations. Our testimony supports projects ranging from wind farms to industrial facilities across 15+ states.
Acoustical Modeling
We employ advanced modeling tools like SoundPLAN and Traffic Noise Model to predict noise levels. Our models use ISO 9613-2 and Concawe standards, integrating CAD/GIS data for accurate 3D predictions. This enables proactive compliance assessment and mitigation planning during project design phases.
