HMMH assists clients with energy and industrial facilities operations and construction to evaluate the impact of noise on neighboring communities, usually for compliance with local ordinances or to respond to complaints. HMMH also assists building developers and architectural clients in meeting specific acoustical design and performance requirements in new and existing buildings. We provide noise measurement and monitoring services, including short-term and continuous long-term outdoors, and diagnostic sound isolation measurements inside buildings. Some of our clients avail themselves of our litigation support and expert opinion services.

HMMH also specializes in mobile source air quality impacts.
