With the help of an acoustic camera that visualizes sound pressure, researchers from the University of Vienna investigated the calls of Asian elephants. The elephants emitted their low frequency "rumbles" mainly through their trunk or through their mouth and trunk simultaneously, and only seldomly through their mouth alone. This is the first study to conclusively demonstrate the combined oral and nasal call emission in a non-human animal. The study has recently been published in the journal "Animals".
