Our world is filled with sound. It exists in even the quietest corners of the planet. But what happens when all that sound is taken away? What is silence? There are very few places on Earth where silence actually exists, but in this episode, Dallas experiences it for himself thanks to a special room called an anechoic chamber. How do our brains process the complete nothingness of silence? Find out as Dallas locks himself alone inside the chamber. Featuring David Alvord and Nick Breen from the Georgia Tech Research Institute.  20k is produced out of the studios of Defacto Sound and hosted by Dallas Taylor.  Follow the show on Twitter & Facebook.
