"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."
