The loudest animal on Earth is the sperm whale. It's the fourth largest animal on Earth and they produce a variety of clicks used for echolocation and communication. These clicks can exceed 230 decibels. For comparison an airplane is generally 150 decibels at takeoff, a rocket is around 200 decibels, and an atomic bomb is anywhere from 220 to 280 decibels! These clicks produced by the sperm whale are so loud that they vibrate a human body which in turn heats the human body and can even cause temporary paralysis. The sounds can travel hundreds to possibly thousands of miles. In fact, some researchers believe that individuals can communicate with other sperm whales on the other side of the planet.
