The Quietest Room In The World Is So Quiet You Won’t Dare Stay More Than An Hour
The Quiet Room built by Microsoft breaks the Guinness Book of Records as the world's most quiet room in 2015. The anechoic chamber at Microsoft Headquarters, Redmond, Washington, USA had been compared to others and it made the record as the world's most quiet room. Two ultra-sensitive tests were performed in the room and they returned an average background noise reading of -20.35 dBA and -20.1 dBA. A decibel (dB) is a logarithmic test scale that measures sound and loudness, the scale starts from 0 which is the softest sound the human ear can detect. It increases in frequency with each level of higher sound intensity. So you can imagine how much sound the ear has the capacity of detecting in an "anechoic room". Anechoic means that the room is without echo and no external sound can pass through. All you will hear is you, the only living thing in the room and the human body is never quite as long as it is alive. People who have experienced being in the room explain that you will start to hear your heartbeat, the and circulation of your blood only after a few minutes of being in the room. One may wonder why this would become unbearing but, the total and utter noise will make you lose your balance due to the lack of reverberation in the room. Ultra-quiet environments are usually louder than we assume. This is why you will also hear the turning of your head and the sound of every breath you take. “When you turn your head, you can even hear that motion. You can hear yourself breathing and it sounds somewhat loud.” Hundraj Gopal, the principal designer of the chamber at Microsoft, previously said. Only a few people have been able to endure being in the room, a maximum of 45 minutes - 1 hour to date. It is impossible to say if anyone will break this record anytime soon but the quiet room holds a deafening silence many have not been able to endure. The Microsoft Anechoic chamber is made up of six layers of steel and concrete and took two years to design. A glance inside reveals the fibreglass wedges, ceilings, and walls that prevent sound waves from access into the room. It remains the world's most quietest room until another anechoic chamber dares to challenge this record.
