Gordon Hempton is the founder of the One Square Inch of Silence Foundation, which recently expanded to become Quiet Parks International with the mission to “save quiet for the benefit of all life.” His books include One Square Inch of Silence: One Man’s Quest to Preserve Quiet, co-authored with John Grossmann, and Earth Is A Solar Powered Jukebox: A Complete Guide to Listening, Recording, and Sound Designing with Nature. He’s also produced more than 60 albums of vanishing natural soundscapes. Despite a dramatic loss in hearing in recent years, he’s been able to release a collection of soundscapes called Global Sunrise: The Musical Sounds of Dawn and a podcast, Sound Escapes.
