Take a Virtual Tour of One of the Quietest Places on Earth
Orfield Laboratories in Minneapolis, Minnesota, is notable for what it lacks. Inside the anechoic chamber, you won't hear the sounds of traffic, chatter, or even the hum of appliances. The soundproof room is one of the quietest places on Earth, and you can take a virtual tour of the space in the video below.
According to UPROXX, Orfield Laboratories is primarily used for research. The background noise inside the chamber clocks in at -9.4 dBA. For comparison, the quietest place the average person has access to has sound levels closer to 30 dBA. Without any outside noises to interfere, products tested for noise levels inside the space produce extremely accurate results. The room has other purposes as well, such as preparing astronauts for space missions and freaking out tourists willing to pay for a visit.
Experiencing sound levels lower than what's found in nature has odd effects on the human body. Your ears adapt to pick up sounds that are usually inaudible. With nothing else to fill the space, the sounds of your heart, stomach, and even lungs can become deafening. Dizziness, anxiety, and out-of-body-sensations are a few of the reported responses to spending time in the eerily silent chamber.
Though you won't be able to get the full experience from home, you can pop in a pair of headphones and get a taste of what the room is like in this video. The lab is currently closed to visitors, but when it's open it offers tours starting at $125 per person.
