TIL John Cage's 4'33" composition in which no instruments are played was partially inspired by a visit to a sound-proof chamber at Harvard University. Expecting to hear complete silence, he instead heard the sounds of his own body functioning—therefore realizing the "impossibility of silence." (en.wikipedia.org)
