There's no need to zone for airport noise in Atlanta because the highway passing through the city center and hotrodded cars already are much louder and more disruptive in practice. I wish I was joking.

Also, the map you're looking at there is relatively low resolution. I would suggest looking at it in https://maps.dot.gov/BTS/NationalTransportationNoiseMap/; make sure to switch the "Modes:" to "All Modes"
