Airport Noise Management 2017 Annual Report The Airport Noise Management Report provides a yearly summary of St. Louis Lambert International Airport s operations and noise complaints. The NAS (National Airspace System) data in this report is from Harris, Inc. and not from FAA official records of operations. This report is illustrative of trends and distribution and should not be construed as official traffic counts. 2017 ANNU AL R EPORT N O I S E C O M P L A I N T S There were 45 noise complaints from fourteen communities received in 2017. There were several noise events which precipitated many of the noise complaints. In March, STL began receiving complaints about loud military aircraft departing in the early morning hours. After contacting Boeing, STL learned that the Air Force was beginning to take delivery of F15s that left in the early morning hours. This would continue over several months. There was a second noise event about numerous low flying F18 aircraft in the late afternoon. Further checking found that ten F18 aircraft landed on June 21 and remained overnight before departing. The aircraft were returning from deployment. Another event was the V-40 Bravo from Scott Air Force Base conducting the touch and goes for IFR training on Runway 29. The plane, which is used to transport the Vice President and other dignitaries, caused alarm to residents who even contacted the TV stations about the low flying aircraft. The complainants stated that they had never seen a large aircraft repeatedly landing and flying over their homes. Other complaints to the noise hotline included complaints about police and TV station helicopters continuously circling and loud and low commercial aircraft waking them up. There were 31 complaints about night time operations (10:00 p.m. to 7:00 a.m.) and 14 complaints were about day time operations ( 7:00 a.m. to 10:00 p.m.). Landings and take-offs (operations) during the day time hours accounted for 87.0% of the operations while 13.0% of the operations occurred during the night time period. Chart below shows complaints by zip code. Three complainants are not shown because they lived in zip codes outside the map boundaries.

Six monitors had decreases ranging from 0.3 to 1.6. Two monitors had an increases of +0.5 and + 0.7. Site 7 was included in the annual average for 2017 although over one month of daily data was missing in the 4th Quarter of 2017. A decrease of 3+ DNL represents a halving of the noise energy. The DNL metric represents noise exposure events over a 24 hour period. The DNL metric approximates the response characteristics of sound to the human ear. The higher the number on the scale, the louder the sound. To account for human sensitivity to noise between the hours of 10 p.m. and 7 a.m., noise events occurring during these hours receive a penalty when the DNL is calculated. Each night time event is measured as if ten daytime events occurred. 75 Noise Monitoring Data Annual Average DNL Years 2015-2017 Year 2015 70 Year 2016 Year 2017 65 60 55 50 45 40 35 Site 1 Site 3 Site 5 Site 7 Site 8 Site 11 Site 12 Site 13
