A while ago I came across an interactive noise map of the globe. Punch in a location and it pops up a map. Zooming out to a state-level seems to remove the noise data, this is a large as I could screen grab.
Interesting to see this above noise map rates industrial zoned for consideration for noise but it doesn’t look like it includes sites like gravel pits.
I’d also come across this map published by the National Park Service for noise in the United States. Bordering on being not more than a population map, you can see some areas of oil extraction show up in North Dakota and Texas. Continental noise maps aren’t as useful when looking for noise by neighborhoods.
MPR published an article from “NPR Staff” that highlighted a noise map from Bureau of Transportation Statistics. This differed from the two above maps in that it includes the airport noise maps lacking in the others.
I’ve zoomed in to this map and it appears there are some graphical glitches in the data. There are some interesting strange noise lines happening up by the Crystal Airport that don’t seem to fit a pattern of airplane use, a strange noisy elbow around Ramsey and another one by Buffalo. Just south of Lake Minnetonka there are single sources that top the charts with noise along TH 7. Glitches? Or maybe there is something noisy happening there?
Still, I found this map among the more useful noise maps simply for the inclusion of airport noise.
