The Anechoic Chamber is the worlds quietest place.
It is a room located at the Orfield Laboratories in South Minneapolis, and it is 99.99% sound absorbent. The walls are double-insulated, and they are made of steel and concrete. Along the walls are 3.3-foot thick fiberglass acoustic wedges which help with the world record quietness.
