Emmy-winning acoustic ecologist GORDON HEMPTON has traveled all over the world recording sounds. In his travels, he noticed that natural silent spaces, places free from mechanical sounds, are vanishing. HEMPTON argues that there are only a handful of silent places remaining in America. Today, we’ll listen to HEMPTON’S recordings of silence and talk about what we’ve lost in all the noise. HEMPTON is the author of One Square Inch of Silence: One Man’s Quest to Preserve Quiet.
