What does the Noise Exposure Map (NEM) identify?

The Noise Exposure Map (NEM) is a critical tool used by airports and local communities to understand the impact of aircraft noise. It specifically identifies present and future noise patterns surrounding an airport. This mapping is essential for assessing how noise from aircraft operations affects local residents and environments over time.

The NEM provides a visual representation of areas experiencing various levels of noise exposure, based on data collected from flight operations, weather patterns, and other relevant factors. This information is vital for airport planners and local governments as it informs decisions about land use, community relations, and noise mitigation strategies. Understanding both current and projected noise impacts allows for comprehensive planning to minimize disturbances and enhance quality of life for those living near airports.
