I hope this helps you clarify the issue and find more info!! I see Aaron pointed out the MAC has an excellent website which details the areas, noise issues, etc......it's great. I have used it myself for a client. Again, it's http://www.macnoise.com/noise
Also, prevailing winds will change the flight path. I live at Hwy. 101 and Cty. Rd. 24 in Plymouth and have been able to read the serial numbers on the wing from time to time! Yikes! My first answer was a flip comment meant to be funny. Ya gotta have a sense of humor sometimes!
I have to disagree with Jeanie's response. Distance from the airport isn't nearly as important as distance from the flight path. Moving a block or two east or west can be better than moving a mile further north if you are in the flight path.
