“The old standard for tracking noise impacts was the Schultz Curve, developed 40 years ago, which tends to consider the irritations from airport noise rise slowly in a shallow curve. It predicted that at 50 DNL hardly anyone was bothered by noise, and by the time noise reached 70 DNL, only 40% of neighbors would be annoyed.”

FAA Seeks Input On Why Air Traffic Annoys Neighbors

NASA’s Advanced Air Mobility mission is developing design tools that manufacturers can use to reduce noise impacts. The Advanced Air Mobility (AAM) project and Revolutionary Vertical Lift Technology project work together to conduct testing with industry partners. The data NASA collects and analyzes from these tests with electric vertical take-off and landing aircraft (eVTOLs) will ensure that the agency’s aircraft design tools correctly predict noise levels for these types of vehicles. With tools that predict noise correctly, manufacturers can design vehicles for quiet operation in urban and rural areas.

The data will also help define and optimize AAM routes and low-noise flight paths for community needs and assist the Federal Aviation Administration (FAA) in creating policy. Lessons learned through these tests will inform the FAA’s ongoing work with operations and airspace integration.”

“Airport noise is a global issue, though the Netherlands may be a special case given that it’s one of the world’s most densely populated countries. Neighbors of Schiphol have recently found that their years of complaints finally paid off: the airport recently announced a series of measures that it hopes will lead to “quieter, cleaner and better aviation.”

The airport plans to ban private planes and cancel all night flights, moves that it estimates would reduce the number of residents experiencing severe sleep disturbance by 54%.”

“

While it may be obvious to the people it affects most, research now confirms that living next to an airport can seriously curtail how much sleep you get. 

Researchers at the Boston University School of Public Health and Oregon State University published a study last month linking increased airplane noise with getting fewer than seven hours of sleep a night, the benchmark of a decent night’s rest for most adults. Shorter sleep duration or low-quality sleep over time can lead to a variety of health problems and affect your overall well-being. “

“Dispersing jet noise and particle emissions is an acknowledged antidote to concentration and is defined as “the process of introducing track variability by changing aircraft lateral position enough to spread out repetitive and intrusive noise events experienced by people living under highly concentrated flight paths” (UC Davis Aviation Noise and Emissions Symposium, February 2021).”
