The visual representation of aircraft noise near O’Hare Airport is presented here, beginning in 1979 and projected through the O’Hare Modernization Program Full Build-Out in 2014, based on Federal Aviation Administration projections.
Since 1979, there have been dramatic reductions in aircraft noise for residents around O'Hare. However, because of how people perceive changes in noise over time these reductions might not be obvious.
Now there is a new graphical depiction that shows exactly how the noise footprint around O'Hare has decreased in the last 26 years. This decrease is due to several factors including advancements in aircraft design, airline fleet mixes, the Fly Quiet Program and the efforts of the City of Chicago and the O'Hare Noise Compatibility Commission to effectively address aircraft noise issues.
