The “anechoic chamber” at Orfield Laboratories is the quietest place on earth and it is unbearable due deafening silence.Most of us would embrace a moment of free time to “enjoy the quiet”. However, the phrase “silence is golden” does not ring true for the Guinness World Record location of the quietest place on Earth which still holds to this day. Ultra-sensitive tests performed on January 21, 2004 determined the background noise reading to be -9.4 dBA (decibel A-weighted). Currently, the record length of stay in the world’s quietest place which is a chamber located at Orfield Laboratories in South Minneapolis is 45 minutes. The silence is achieved with the use of 3.3 feet of fiberglass acoustic wedges, double insulated steel and concrete that is a foot thick.
