Airport Noise Management System Reports

​Installed in 1996, the Airport Noise Management System (ANMS) enables the City of Chicago to monitor the amount of noise being generat​ed over the comm​unities surrounding O'Hare by the aircraft operating at the Airport. The ANMS collects, analyzes and processes data from a number of sources of information including a network of 43​ noise monitors around O'Hare, FAA radar data, weather data and noise complaints. Over 150,000 fligh​ts and 400,000 noise events are recorded by the ANMS each month for the Chicago Department of Aviation. The City of Chicago and the O'Hare Noise Compatibility Commission​ utilize data from the ANMS to facilitate the development and management of noise abatement p​rograms at the Airport. The following reports summarize pertinent monthly information from that data concerning the noise levels a​nd opera​tions at the Airport.
