How is aircraft noise measured?
The Federal Aviation Administration (FAA) utilizes the Integrated Noise Model (INM), which is a computer model that generates the noise exposure map. Factors that influence INM include number of aircraft operations, fleet mix, runway operations, flight track usage, weather, and nighttime operations.

The exposure map is also known as the DNL contour. DNL stands for day-night average sound level and is an average of daily noise exposure over an annualized period. DNL contours ultimately determine which areas and homes are eligible for MAC funded mitigation programs, including the sound mitigation program.
