I get all that. But in today's world of the carbon religion paranoia, the places that go ballistic the most about that are the same places that demand less efficient tracks for noise, and the noise itself is mostly perception. No "community" should have the right to regulate noise if it comes from a plane versus the same db from other sources.
The vast majority of the time now, if you hear a plane its barely audibile compared to school busses and mail trucks and garbage trucks and lawnmowers and weed wackers and sometimes even chirping birds. Nobody should be able to adjust ground tracks of planes for that just because they hear something they can eventually attribute to being an airplane because of stupid preconceptions from the 1970's.
