Anechoic Chamber at the Orfield Laboratories, Minneapolis.

Orfield Laboratories in South Minneapolis is home to the Anechoic Chamber, also known as the world’s quietest room – a title confirmed by Guinness World Records.

But while the room promises to provide complete silence, it can’t guarantee visitors will be at peace once inside.

The quiet chamber amplifies even the slightest noise, making people accurately aware of anything, including the sound of their heart beating. In fact, the sensation is so intense – including the possibility of hallucinations – that no one has been able to stay in the room longer than 45 minutes, according to the Deccan Chronicle.

The room, which is used for testing devices such as hearing aids, measures at an eerily quiet -9 decibels. To put that number in perspective, a typical quiet room where most people sleep measures 30 decibels, according to Minnesota Public Radio. In the chamber, sound is absorbed instead of bounced off the walls.

Orfield Laboratories in South Minneapolis has an “Anechoic chamber” that holds the Guinness World Record for the world’s quietest place. The room gets so silent that you can actually hear your internal organs at work. And after a while, the hallucinations begin.In fact, the longest duration of time spent in the room is 45 minutes.

NASA uses a similar chamber to put their astronauts through various tests. They are made to float in there in a water-filled container, to see how long it takes before hallucinations begin and whether they could work through it. Because believe it or not, outer space is just one big anechoic chamber – the silence out there is just too loud.
