About Gordon Hempton - the Sound Tracker®
BOOM Library is very proud to distribute the probably best nature recordings on the planet, the absolutely precious recordings of Gordon Hempton.

Environmental activist & Emmy-Winner
All of the nature sounds in the QUIET PLANET Nature SFX series were recorded by Gordon Hempton, The Sound Tracker®, Emmy-winner, author of One Square Inch of Silence, and environmental activist. Faced with habitat loss, species extinction and most of all unbridled noise pollution, Hempton has now turned his attention towards saving the world’s few remaining natural amphitheaters.
The highest appreciation for mother earth's voice
Gordon Hempton cares very deeply about quiet. As The Sound Tracker® he has circled the globe three times over the last 35 years in pursuit of Earth’s rarest nature sounds — sounds which can only be fully appreciated in the absence of manmade noise. These recordings are available through BOOM Library's QUIET PLANET series.
