The number of people exposed to significant airport noise in the United States has decreased from 7 million people in 1975 to approximately 309,000 people in 2012, according to the Federal Aviation Industry (FAA), which cites an initiative to improve aircraft engine and airframe technology to reduce noise, fuel burn, and emissions as one of the factors in the change.
The FAA also works with communities to eliminate or mitigate incompatible land use near airports and provides federal funds to mitigate the adverse impacts of aircraft noise in homes and schools near airports.
