The quietest room in the world
It is said that silence is gold. But in the U.S. there is a room in which is so quiet that to be in it for a long time is simply impossible. People can survive in the "anechoic" room a maximum of 45 minutes.This room is capable of absorbing the sounds of 99.99% and is included in the Guinness Book of Records as the quietest place in the world. If you're too long in it, then you may even be hallucinating.
