Responsible airport operations require careful noise monitoring and management. This helps Centennial Airport understand its impact on the surrounding community and environment, while guiding efforts to reduce and mitigate those effects.
To achieve this, the airport uses the Airport Noise and Operations Monitoring System (ANOMS)—a sophisticated platform combining remote noise sensors, radar-based flight tracking, and advanced analytical tools.

How ANOMS Works
ANOMS operates through a network of permanent and temporary noise monitors, usually placed near flight paths. These devices measure and transmit noise levels every second, 24/7, to a central system.
When noise exceeds background levels for a significant period, the system records a “noise event.” Events may be triggered by a variety of sources—such as vehicles, wildlife, weather, or aircraft. To determine whether an aircraft was responsible, ANOMS integrates radar data directly from Air Traffic Control (ATC), the same data ATC uses to safely manage air traffic. This allows ANOMS to match flight paths with noise monitors and link specific flights to noise events.
Distinguishing Aircraft vs. Community Noise
Not all noise events come from aircraft. ANOMS can identify community events caused by cars, sirens, birds, or other everyday sounds. By separating aircraft-related events from community noise, the system builds an accurate picture of the overall sound environment.
Adding Context with Weather Data
Noise is also influenced by environmental conditions. ANOMS incorporates weather data, since strong winds, thunderstorms, or cloud cover can alter flight paths and change how noise travels and is perceived on the ground.
Why It Matters
By combining flight, noise, and weather data, ANOMS provides Centennial Airport with a detailed understanding of its environmental footprint—helping ensure operations remain safe, responsible, and responsive to community concerns.

Portable Noise Monitors
Centennial Airport maintains 2 Portable Noise Monitors that can be deployed anywhere in the community. The airport regularly deploys these in areas of concerns or may even deploy them at the request of a resident. Requests for portable noise monitor are not guaranteed and are evaluated on a case-by-case basis. To request a portable noise monitor, email: Zach Gabehart, Noise & Environmental Specialist at zgabehart@centennialairport.com.
