ambient music

"Writing in the 1960s, Serge Chermayeff and Christopher Alexander argued that: Under present conditions men are beginning to lose the capacity to discriminate between sound and noise - between the desirable and the irrelevant...The problem of isolating undesirable sounds is technically so hard to solve that acoustics engineers now recommend the simpler expedient of providing artificial background noise in one's own domain as an acoustic cushion or muffler. Making more noise is the only economical way, apparently, of drowning out unwanted noise and of not being overheard. It seems that the illusion of quiet can only be maintained in noise."
