Loudest Animal On Earth

Blue Whales are not only the largest animal on Earth, they are also the loudest.

Picture from Bay Schools

The call of the blue whale reaches levels up to 188 decibels.  A jet reaches up to 140 decibels, while a shouting human can reach up to 70 decibels.  Sounds over 120 decibels are extremely painful to the human ears.  A blue whale's amazingly loud whistle can be heard for hundreds of miles underwater.
