The Quietest Place On Earth

The quietest place on earth, an anechoic chamber at Orfield Laboratories in Minnesota, is so quiet that the longest anybody has been able to bear it is 45 minutes. Inside the room it's silent. So silent that the background noise measured is actually negative decibels, -9.4 dBA.
