The Quietest Place On Earth Is Located Where?
Answer: Minneapolis, Minnesota
There are places on Earth that are naturally quiet due to their isolation and lack of environmental disturbances, such as the barren snow fields of Antarctica or the sprawling and deep limestone caves located under the U.S. state of Kentucky. As eerily quiet to the human ear as these places are, however, they’re practically a busy city street compared to the silence found in a man-made chamber located in Minneapolis, Minnesota.
In an unassuming building there, owned by Eckel Industries, you’ll find the Orfield Labs. Part of the Orfield’s research space includes the world’s officially quietest anechoic chamber–a space designed to absorb and isolate sound. The chamber is so effective that the ambient level of noise inside is actually -9.4dB; the quietest space on Earth. Visitors to the chamber report that the space is extremely disconcerting to spend any length of time in as the walls do such an effective job at absorbing even the tiniest environmental sounds (like the rustling of clothing or a cough) that it disorients the brain to the point that some people report vertigo, nausea, and other unpleasant reactions to standing inside.
