Memes, The Voice, and Voice: The 'Center of the universe' located in Tulsa is an incredible acoustic
 anomaly that seems to defy the laws of physics. When you stand inside
 the concrete circle and make a noise, the noise is echoed back and is
 heard much louder than the original one. But it is inaudible to anyone
 outside the circle. Not only the effects resides inside the circle, but
 outside too. The Voice of a person standing outside of the circle also
 becomes distorted when heard across the circle.
