History

Harris Miller Miller & Hanson Inc. (HMMH) was founded in 1981 to provide the highest quality noise consulting services to airports.  A spin-off from Bolt Beranek and Newman (BBN), HMMH’s founders worked on some of the earliest, ground-breaking transportation noise challenges, including early work for the Port Authority of New York and New Jersey and Amtrak’s Northeast Corridor.

Today, in addition to our noise practice, HMMH addresses emerging and technologically challenging challenges including air quality analysis, airport and airspace planning, and climate and energy solutions. HMMH is nationally recognized for developing complex solutions for issues affecting our environment.

Nicholas Miller, Senior Vice President

Nicholas Miller started his work in environmental acoustics in 1970 at the University of North Dakota, completing a Master’s Thesis based on scale modeling of sound propagation in urban canyons.  In 1973, he began working at BBN in highway noise and regulatory acoustics.  Helping to found HMMH in 1981, he has since worked on most aspects of aviation noise and vibration, from assessing the effects of aircraft noise on building vibration, to environmental studies of new or lengthened runways, to computer model validation and refinement, to quantifying the effects of aircraft overflights on national parks.  In recent years, Mr. Miller has designed and developed Virtual Soundscapes™, an HMMH innovation that permits users to hear realistic recordings of existing and future environments. Mr. Miller was President of HMMH from 1989-2004 and as a Senior Vice President of HMMH, he is responsible for project management and marketing of consulting services in aviation and other noise related studies. 

   
Carl Hanson

Carl Hanson, Ph.D., P.E., Retired

Dr. Carl Hanson was active on rail transportation projects since 1972 until his retirement from HMMH in 2011 - first at BBN from 1972-1981, and then as a founder of HMMH in 1982. Dr. Hanson was active in a wide range of projects including noise control designs of vehicles and facilities, compliance tests, environmental assessment, community measurement programs and expert testimony. He was especially active in the area of high speed rail and maglev systems, having conducted research and consulting projects in the United States and Europe.
