Noise Surveys & Impact Assessments

Our noise consulting services help clients understand, predict, and manage the effects of noise generated by project development. 

Noise assessments measure existing sound levels in the field, identifying noise-sensitive locations such as residences, schools, parks, and businesses, and using specialized modeling tools to evaluate future conditions and potential impacts. These studies help project teams comply with environmental regulations, support permitting requirements, and determine whether noise mitigation measures such as barriers, alignment modifications, or operational changes are warranted.

We deliver comprehensive transportation noise impact assessments that integrate advanced noise prediction modeling, field data collection, and mitigation strategy development to ensure projects meet regulatory standards and minimize community noise impacts. The team is comprised of capable Geographic Information Systems (GIS)  specialists, working in tandem with ArcGIS products and Federal Highway Administration (FHWA) Traffic Noise Model (TNM) version 2.5 to develop traffic noise models, and their GIS capabilities is an added benefit for data exchange with clients and developing web-based GIS tools for public involvement.
