It's difficult anywhere in Northern VA to find an area that doesn't experience airport noise/road noise, and especially so along the Rt. 50 corridor. Having said that, the only way to get the real answer to your question is to sit out there for a bit and see what YOU think of it. Everything else on this matter is a matter of opinion. What counts is what you think.
I can tell you from a resale standpoint, having sold homes in that community and area, airport noise has not come up once. Either b/c buyers don't think it's an issue or b/c buyers are all accustomed to some level of airport noise.
Hope this helps somewhat; feel free to call or txt if you'd like to discuss further.
All my best,
