HMMH provides best in the business noise consulting services, which has enabled Louisville Regional Airport Authority to continually assess and improve aircraft noise in our community neighborhoods surrounding the Louisville Muhammad Ali International Airport. Due to their unparalleled expertise and ability to comprehensively communicate the difficult subject of noise, HMMH continues to provide LRAA and our Community Noise Forum upon request with timely, accurate and easily understood information. I have no hesitation recommending HMMH to help your airport address community noise concerns because frankly they do it right.

HMMH did a first-rate job. The results of the study were exactly what we were looking for to help strike a balance between the rights of residents and the need for a local business to thrive and foster the area’s tourism industry. HMMH would be my first call when faced with a similar problem in the future.

HMMH’s efforts were instrumental in the Authority’s ultimate success in providing an outstanding project that exceeded FAA requirements, met our noise-impacted community’s expectations and stayed within our budget. I would highly recommend HMMH to any airport that demands a successful, transparent and quality project.
