HMMH has addressed and resolved environmental noise and air quality problems in airspace sectors, airports, heliports, and military bases throughout the United States and around the world. Our federal clients include the Federal Aviation Administration (FAA), the Navy, the Air Force, the Department of Justice, and the National Park Service (NPS). We also provide solutions to airport proprietors and industries in the private sector such as airlines and aircraft manufacturers.
Our work has earned us an international reputation for technical excellence and for expertise and insight into regulations and review processes. We are equally renowned for our ability to communicate effectively with the public.
We are a leader in developing noise and land use compatibility plans under Title 14, Code of Federal Regulations (CFR) Part 150 and 161, in the design, specification, and installation of airport Noise and Operations Monitoring Systems (NOMS), in acoustical testing for airport sound insulation programs, and in conducting airport ground noise studies. Our air quality services include air permitting and dispersion modeling, greenhouse gas analyses and emissions inventories, ambient and meteorological monitoring, and VALE project funding assistance. We have a vast amount of project experience in both airport noise and air quality.
HMMH provides a broad range of training seminars and courses for airport noise offices, state and local government agencies, aviation businesses, and federal agencies such as the FAA and the NPS. We have developed manuals and guidelines on noise and vibration control for the FAA, Environmental Protection Agency, and the NPS. HMMH has trained more than 400 professionals on the use of the FAA’s Integrated Noise Model (INM) and Department of Defense’s NOISEMAP.
