Bowlby & Associates, Inc. offers expert assistance in transportation and community noise analysis and mitigation. We have completed hundreds of noise studies for federal projects per the FHWA noise regulation, Procedures for Abatement of Highway Traffic Noise and Construction Noise, 23 CFR 772, and state noise policies for an extensive list of DOTs. We have evaluated all types of highway projects, including complex interstate widening and interchange projects, new alignments, widenings, bridge replacements, and truck climbing lanes. We have managed many noise barrier projects from environmental through design and construction. We also perform noise studies to meet the Department of Housing and Urban Development (HUD) requirements per 24 CFR Part 51, Subpart B.

Our experience also includes evaluating noise policies and procedures for state and federal government agencies, assessing noise barrier priorities and needs, determining noise barrier effectiveness, and evaluating tire-pavement noise.
