There are animals in the Ocean that make noises as loud as this..
Take the Pistol Shrimp for example: http://en.wikipedia.org/wiki/Alpheidae
That makes 200db's just by snapping it's big claw.. (albeit at a much shorter range)
Interestingly the 'explosion' caused by the snapping reaches temperatures close to that of the suns surface!
