New Map Shows USA's Quietest Places
sciencehabit writes Based on 1.5 million hours of acoustical monitoring from places as remote as Dinosaur National Monument in Utah and as urban as New York City, scientists have created a map of noise levels across the country on an average summer day. After feeding acoustic data into a computer algorithm, the researchers modeled sound levels across the country including variables such as air and street traffic. Deep blue regions, such as Yellowstone National Park in Wyoming and the Great Sand Dunes National Park in Colorado, have background noise levels lower than 20 decibels — a silence likely as deep as before European colonization, researchers say. That's orders of magnitude quieter than most cities, where noise levels average 50-60 decibels. The National Park Service is using the map to identify places where human-made noise is affecting wildlife.
Well given I live in the woods I will tell you that they are not quiet!
Come sundown the cicadas go mental and their noise can make talking to someone else hard. Then there are all the birds! Do you know how loud a cockatoo is!!! Let alone a kookaburra! Then at night you get the demonic noises of fighting possums, the sounds of male koalas and all the frogs. Damn you frogs!
And then if you really really really want to hear a noise that will chill you to your bones - https://www.youtube.com/watch?... - that is the sound of the Curlew. When you hear that for the first time in the middle of the night........
It might be a different noise to cars, or sirens, or some morons crap music. But woods, quiet they are not!
