Matt Mikkelsen is a documentary film maker, sound recordist and environmental activist in an unusual cause: the preservation of "natural silence"soundscapes undisturbed by the noise of human activity. He works with Gordon Hempton on the One Square Inch of Silence project, symbolised by a small red stone placed in the centre of the Hoh Rain Forest in Olympic National Park, Washington State, the so-called "quietest place in America." Matt, along with cinematographer Palmer Morse, is also the creator of the award-winning short film Being Hear, which documents Gordon's work and philosophy. Its message is not only about the importance of preserving places of natural silence, but also about the value of deep listening in a society drowning in noise.
