Elephants might have their own language, one that's communicated through a series of ultra low-frequency rumbles. A new study called the Elephant Listening Project (ELP) is attempting to decode Dumbo by analyzing over 300,000 hours of audio captured from infrasonic (super sensitive) microphones hidden in trees in the forests of Africa.
The rumbles are one of the team's most interesting discoveries. While they happen at a frequency almost too low for humans to hear, the noises can be heard for several miles. Mothers will sometimes use a rumble to tell their children to stop playing (pshh, typical mom), or to greet old friends they haven't seen in a while. When it comes to elephants, females are traditionally the chatty ones, while male elephants often just standby and watch.
