Louisville, KY Noise Ordinances: Aircraft Noise (2026)

Because federal law preempts most local regulation of aircraft operations, Louisville Metro cannot impose curfews or noise limits on overflights. SDF is a Part 150 airport with an FAA-approved Noise Compatibility Program administered by the Louisville Regional Airport Authority (LRAA). The UPS Worldport, located on the south side of SDF, generates its peak operations between roughly 10 PM and 4 AM when hundreds of cargo aircraft sort packages, making overnight aircraft noise a defining feature of neighborhoods south of the airport including Prestonia, Highland Park, and parts of Okolona. LRAA has historically operated a Residential Sound Insulation Program (RSIP) that funded acoustical treatment — new windows, doors, attic insulation — for homes inside the 65 DNL contour. Eligibility depends on the home being within the approved noise contour at the time of the program round. Noise complaints can be logged with the LRAA Noise Program Office. Ground noise from engine run-ups and APUs is partially managed by designated run-up pads. Residents considering a home purchase near SDF should review the current DNL noise contour map published by LRAA and factor in overnight cargo operations, not just scheduled passenger flights.
