The world’s quietest room is located at Microsoft’s headquarters in Washington state. In Building 87 of Microsoft’s headquarters in Redmond, Washington lies the quietest room in the world. With a record-breaking background noise of -20.35 dBA, this room is 20 decibels below the minimum of human hearing. It is so silent that if you stay in it for long enough, you’ll start to hear your heartbeat, a deafening ringing in your ears, and the grinding of your bones. To achieve absolute silence, the room was constructed with an onion-like structure made of six layers of concrete and steel.
100 Mind-Blowing Background Facts

The heat from the Big Bang is still around today. The early Universe consisted of a hot soup of ionised gas: a sort of opaque plasma. About 380,000 years after the Big Bang, this gas cooled sufficiently enough that atoms were able to form. Radiation left over from the Big Bang is still around us today and is known as the cosmic microwave background (CMB). It can’t be seen with the naked eye, but various missions over the years have been able to study it in microwave light, including ESA’s Planck satellite and the WMAP mission.
Reindeer in the Arctic can see the world in ultraviolet light. While we cannot see ultraviolet (UV) light, reindeer seem to have developed this ability after moving to the Arctic. They likely evolved this ability to assist them in a world that would otherwise be very bright and white. Under UV light, both food and predators stand out much more against the harsh snowy background.
The quietest place on Earth is in Minnesota.

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.
