O'Hare Noise Mitigation
Aircraft Noise Complaints
Official aircraft noise complaints include all complaints submitted via telephone to the O’Hare Noise Hotline or via our online form. The complaints are then forwarded to the Chicago Department of Aviation (CDA) for tracking purposes only and will be included as data in the Airport Noise Management System reports.
There are two official ways to submit a complaint:
Submit Complaint via Telephone
The CDA maintains a toll-free noise hotline (1-800-435-9569 for suburban communities or 311 within the City of Chicago) for citizens to express their concern about particular aircraft events or aircraft noise levels in general.
Submit Complaint via Online Form
In June 2009 the City of Chicago launched a webpage where complaints may be entered directly online. The link below leads to the City’s 311 System where one can fill in information about a noise event.
If you are trying to enter a complaint online and are receiving an error message, please call the Noise Hotline and let the operator know the webpage is down.
Does my home qualify for sound insulation?
When the FAA issued the ROD, the ROD identified the 65 DNL Build-Out Noise Contour as the noise contour to be used for sound insulation purposes. Noise contours for interim conditions are not used for sound insulation purposes. Each home must also meet additional eligibility criteria as established by the City and the ONCC. For more information, please call the City’s Residential Inquiry Line at 773.894.3255 or visit the Property Locator .
