The Chicago Department of Aviation's Airport Noise Management System (ANMS) is a comprehensive system to provide actual measurement of the aircraft noise levels in Chicago neighborhoods and suburban communities around O'Hare and Midway. This integrated system includes many components, including a network of permanent noise monitors that measure the noise environment and a system directly connected to the FAA's air traffic control radar that collects aircraft flight tracks. More than 5 million data points are recorded and stored by the system each day.
Feedback from our neighbors is crucial to the success of this program. The information from citizens about airport noise in neighboring communities is also entered into the system. The Chicago Department of Aviation (CDA) will use this data as the basis for working with the Midway Noise Compatibility Commission (MNCC), the Federal Aviation Administration (FAA), the airlines, and communities on future programs aimed at reducing noise impacts on residential communities.
