GORDON HEMPTON IS AN “ACOUSTIC ECOLOGIST” who has spent more than 30 years traveling and recording sound. Through his research, Hempton has determined the “quietest square inch in the United States”: a patch of the Hoh rainforest in Olympic National Park. Hempton defines “quiet” not by silence or lack of sound, but by lack of manmade noise. Some estimates show that noise pollution affects more than 88 percent of the U.S. The spot in Olympic National Park has less noise pollution than any other spot in the United States. In an article for Crosscut, Hempton describes how he aims to protect spaces like these from the invasion of noise pollution and reconnect Americans to the spirituality of nature.
