Quiet Zones

Two noise stories showed up page one in today's paper. One dealt with the continuing issue of the noise from inbound commercial aviation. The other had to do with horns from passing commuter trains are bothering residents of Atherton and city officials want to enact the provisions of a federal regulation to establish a "quiet zone". Granted, sometimes noise can be a problem and goodness knows living next to railroad horns can't be pleasant, but I've noted in the past that these complaints generally come from some of the more well off communities and that might suggest that these people both use airtravel disproportionally and have the means to relocate to suit their noise tolerance. Then again, I might want to reserve federal "quiet zone" laws for use against these same people using their cell phones where it bothers me.
