I'm not sure why people who can afford modern houses complain about noise levels; I'm living right under the flight-path for SJC and it is super loud. But if you close a double pane window? it's pretty quiet; my place has a third single-pane of glass on the outside of that, and if I close the doors and windows? the place is just about silent, no matter how many airplanes go overhead. It's not a fancy building, either; the construction is typical of the late '80s, early '90s, I think, aside from the third pane of glass, which I think was a retrofit.
