The Chicago Department of Aviation provides monthly reports to O’Hare Noise Compatibility Commission members based on the Airport Noise Management System (ANMS). The ANMS is a comprehensive system designed to provide actual measurement of the aircraft noise levels in Chicago neighborhoods and suburban communities near O’Hare Airport.

The ANMS integrated system includes many components including a network of 32 permanent noise monitors that measure the noise environment. The system directly connects 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.

At the direction of the ONCC, the ANMS and report compilation methodology were independently verified by an aircraft noise expert.

Installed in 1996, the Airport Noise Management System (ANMS) records noise events that are summarized by month in four categories: Runway Use, Aircraft Noise, Aircraft Fleet Mix, and Noise Complaints.

Data from Permanent Noise Monitors and/or Long-term Portable Monitors does not determine eligibility for residential or school sound insulation.

The Chicago Department of Aviation and ONCC use ANMS data to facilitate development and management of noise mitigation programs at O’Hare.
