Aljazeera: Big Bang not so big:

The explosion that assuminglyÝgave birth to the universe sounded not so much like a Big Bang than a Deep Hum.

The New Scientist, a British weekly, has said a computer model of the likely audio frequencies generated by theÝBig BangÝhas been created by physicist John Cramer of the University of Washington in Seattle.

"The sound is rather like a large jet plane flying 100 feet (30m) above your house in the middle of the night," he said.
