The National Parks Service has created two maps: one that tracks noise pollution throughout the United States, and another that maps what the country would sound like without humans and our noise. And what do the maps show? Dan Mennitt, the park service researcher behind the maps, states:
There’s nowhere in the lower 48 where you can sit in a national park or any other natural area and not hear aircraft. There’s no such thing as a noise-free day anywhere.
