Known as “the quietest room on the planet” according to the Guinness Book of Records. An anechoic chamber (no echo) created by Microsoft in Redmond, Washington, North America, allows you to hear the circulation of blood in the body.
The room is made up of six layers of steel, fiberglass screens, and vibration-damping springs that block sound waves, used to test audio equipment and electronic devices. Here, the background sound is -20.35 decibels, which is lower than in the library, which recorded about 40 decibels, explains new york post office.
The absence of noise allows us to hear the circulation of blood in our body, as well as our breathing and even the crunch of bones. The experience can be unsettling to the point where the concept of space and thus balance is lost.
According to the company, the maximum time someone could be in a room was just one hour.
