It has been suggested that African savanna elephants Loxodonta africana produce 31 different call types (Langbauer 2000). Various researchers have described these calls by associating them with specific behavioural contexts. More recently Leong et al. (2003) have attempted to classify elephant call types based on their physical properties. They classified 8 acoustically distinct call types from...
Unlike the smaller and more vulnerable mammals, African elephants have relatively few predators that threaten their survival. The sound of disturbed African honeybees Apis meliffera scutellata causes African elephants Loxodonta africana to retreat and produce warning vocalizations that lead other elephants to join the flight.

In the wilds of Africa, when it’s time for a family of elephants gathered at a watering hole to leave, the matriarch of the group gives the “let’s-go rumble” — as it’s referred to in scientific literature — kicking off a coordinated and well-timed conversation, of sorts, between the leaders of the clan. First, the head honcho moves away from the group, turns her back and gives a long, slightly ...

The RUMBLE project aimed to quantify the effects of low sonic boom exposure on human responses, in situations representative daily life European citizens, so as inform policy, establish standards and develop protection concepts for a new generation supersonic commercial aircraft that should emit reduced but perceivable (a “low boom”) while flying overland. Two simulators were affixed bedrooms’ ...
