A Room Built for Total Silence


John Cage famously sat in Harvard's anechoic chamber for a period of time and emerged with a striking observation: "I heard two sounds, one high and one low. When I described them to the engineer in charge, he informed me that the high one was my nervous system in operation, the low one my blood in circulation." JC's conclusion was that there could therefore be no such thing as silence. As long as we live, a fundamental, background hum, pervades our experience. -Ann Hedonia
