These days, silence can be hard to come by. Unless you are fortunate enough to live in the countryside or a more rural area, you can pretty much guarantee that there will always be some sort of background noise. We all seek it from time to time, but would you really be able to stand total silence? The ‘anechoic chamber’ at Orfield Laboratories in South Minneapolis is so quite it has been known to cause hallucinations.



Its walls are 99.9% sound absorbent, and the silence so deadening that the longest anyone has been able to spend inside the room is 45 minutes. The room currently holds the Guinness World Record for quietest place on earth with a background noise reading of -9.4 decibels. It achieves its silence thought the use of 3.3-foot-thick fiberglass acoustic wedges and double insulated walls of concrete and steel.
