Computations in Airplane Noise Study

This post offers some background related to the conversation about airplane noise in Belmont and Watertown including some downloadable data.

This post is basically an exploration of the data. But it does yield a bottom line insight: flights departing from runway 33L are very concentrated over two narrow corridors in Belmont and Watertown, but spreading them out by as much as 1000 meters in either direction would not make a detectable difference in experienced noise levels.
