The sound level of an average anechoic chamber is only around 30 decibels, but this Guinnes World Record quietest room in Orfield Labs, Minneapolis is having -9 decibels of sound level in the room, according to MPR News. Threshold of human hearing starts from 0 decibel and imagine you are trapped in a room with -9 decibels sound level? Definitely will go crazy after sometime. According to the experiment, the longest a person has ever spent alone in the chamber is 45 minutes as human start to hallucinate as the surrounding is too quiet.
Any way, just for your information, the world quietest room is built not for entertainment or just to break record. Orfield Labs built and uses this anechoic chamber to test the noise levels of various products such as LED lights, medical equipment and so on.

*Attention!* Check this link which is about Charlie who produce the podcast Composer Quest (not the point though). But this guy has a great blog sharing his experiences and knowledge about music composition, production, sound and psychology that might makes you 'Wow' about facts that you might not know earlier. And pss.. he had already visited the quietest chamber!
Note: Anechoic chamber (an-echoic meaning non-echoing/echo-free) is a room designed to completely absorb reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. The combination of both aspects means they simulate a quiet open-space of infinite dimension, which is useful when exterior influences would otherwise give false results. Source by wikipedia
This is something new to me. Never knew a place like this existed. Good job in finding it. I suppose this confirms the theory that sound (or lack of) often has the biggest psychological impact on humans. Silence and noise affects us in the most profound ways and it's just that we have never really stopped to consider the implications. In terms of architecture and interior design, we hardly consider how much sound a space or a building makes or lets in. Creating the perfect decibel level should be as important as creating an aesthetically pleasing view.
