Since 1996, the Airport Noise Management System has enabled the City of Chicago Department of Aviation (CDA) to monitor the amount of noise generated from aircraft operating at Chicago O'Hare and Midway International Airports. The portable noise monitors allow the CDA to provide residents with specific information on aircraft noise levels at a specific home during a sample two-week monitoring period. This information is for your information only. Due to strict Federal Aviation Administration (FAA) guidelines, the data collected by the portable noise monitor will not be used to determine eligibility for our sound insulation programs.

Once you have submitted the application to the CDA (see link to PDF below), we will contact you to set up a date for deployment. After the portable noise monitor has been deployed and the monitoring is complete, the CDA will provide you with a detailed summary report of the aircraft noise measurements. This report usually takes approximately four weeks to prepare and distribute.
