WORLD’S QUIETEST ROOM (IMAGES & VIDEO)
https://www.jebiga.com/worlds-quietest-roomThe World’s Quietest Room is located in Orfield Labs in Minneapolis and it is an anechoic chamber. The idea was to create walls, floor and ceiling that absorb sound rather than have it bounce off as it does generally. A normal quiet room has a sound level of about 30 decibels, while humans can only hear sounds that are above 0 decibel.
