The quietest place on Earth is in Minnesota. Pretty much wherever you go in the world, there’s always going to be some sort of background noise, whether that’s the chirp of crickets or the slow, lazy whoosh of a gentle breeze. That’s the case everywhere except Orfield Laboratories in Minneapolis, Minnesota, where something called an anechoic chamber lies. While the background noise in a tranquil bedroom measures somewhere around 30 decibels, Orfield Laboratories anechoic chamber recorded an average of -13 decibels – that’s so quiet that the inner workings of your body are audible.
