I recently moved to One Loudoun again after being here in 2020-2021, never have I ever noticed the plane noises during this time because I guess the route they took to land used to be different. Now I am seeing a bunch of articles based on One Loudoun/Ashburn residents complaining about the noises, and I can also assure you that YES, they did make some change this previous 1-2 years and its insanely loud. There are properties in my neighborhood that are valued at around 1.75m+ but you will hear roaring sounds of the engine and aircrafts flying over every 5-10 minutes. I thought I was crazy and that I didn't notice it back then, but I did my research and found this article from
https://www.washingtonpost.com/transportation/2022/08/09/dulles-airport-noise-loudoun-county/ and it made me realize that they did indeed make some changes... It doesn't bother me that much but its just kind of annoying how frequent I hear it and how much we pay to live out here. I'd recommend living in Stone Ridge or South Riding (older areas) that I grew up in, that didn't hear so much of the loud plane noises. Hopefully I can move out of Virginia for GOOD!
