Silence, usually cause us a sense of calm, but the quietest place on earth drives people crazy.
Or field Labs, acoustic booth in Minnesota, United States, officially registered in the record books as the quietest place on Earth. This is, in fact, anechoic chamber, where you stand on the floor of the grid, and the walls around you are faced with large sound-absorbing wedges of fiberglass.
Want to try? Then I want to warn, though here and quiet here insanely scary. After going through two thick doors, the last sound you hear is the sound of slamming doors. In fact, you will find yourself in a dark room; the light is not included because even lamps can make a room for a couple of decibels louder, though you will not feel it. The door closed, and a second later the noise level drops to -9 dB (familiar to us, "silence" yelling about -30 dB). External noises are completely absent and the brain starts to go crazy. You start to hear the heart beating as gurgles cucumber with milk in your tummy.
Steve Orfield Labs owns Orfild. He loves all those who said that stand the test of peace and happily runs them in the camera. Most cannot stand and 20 minutes and go from there completely disoriented and with crazy eyes. The owner cannot beat your record stay in the room, is 30 minutes.
In addition, to scare people, anechoic chamber serves as a testbed for various manufacturers of acoustic products that use the quietest room in the world to make measurements of interference in their products.
