Answer 2

It's the blue whale....

        "Some of their vocalizations have been recorded as loud as 188 decibels and can be heard as far as 530 mi/848km away. To give you an idea of just how loud 188 decibels is a commercial jet taking off makes a sound of 120 decibels. That makes whales, by far, the loudest living thing anywhere on earth!"
