Navy aircraft sound monitoring study

The United States Department of the Navy (Navy), as directed by Congress, executed a real time sound monitoring study of jet aircraft at Naval Air Station (NAS) Whidbey Island and NAS Lemoore over the past year and compared the resulting measured data with modeled noise data. The Navy collected real-time aircraft sound level and operational data during four discrete seven-day monitoring periods in 2020 and 2021. The data collected each period included: (1) acoustic recordings by sound level meters deployed at sites around each airfield to capture sound levels during a range of flight operations across a range of seasonal weather conditions; and (2) detailed operations data. The collected acoustic data are compared to noise modeling done specifically for this study using the observed flight operations data. This presentation provides and overview of the measured data and the results of the comparison with modeled data.
