garadinervi: The Harvard Anechoic Chamber (“Beranek’s Box”), Harvard University, Harvard University Archives, 1941-1971. Designed and built by Dr. Leo Beranek Acoustically isolated echo free box lined with 19,000 fibreglass wedges each 3′ long (x) to disrupt and absorb sound waves (https://doi.org/10.1121/1.1916351)John Cage would famously recount of his experience in Harvard’s anechoic chamber: “..in that silent room, I heard two sounds, one high and one low. Afterward I asked the engineer in charge why, if the room was so silent, I had heard two sounds. He said, “Describe them.” I did. He said, “The high one was your nervous system in operation. The low one was your blood in circulation.” -- source link
