Question

How many distance sound of african elephant travel ?

Answer 1

How far do infrasonic elephant calls travel?

The lower the frequency of a sound, the longer its sound wave. Low frequency sounds can therefore travel farther without being absorbed or reflected by the environment. Intensity of elephant calls varies widely from very soft calls made between mothers and their adjacent infants to the very loud calls made by females announcing their availability. Playback experiments demonstrated that savanna elephants responded to each others’ loud vocalizations over distances of at least 2 kilometers. Because playbacks were only broadcast at half the amplitude of the strongest elephant calls in their sample, the authors estimated the actual range as at least 4 kilometers (Langbauer, Payne et al, 1991). The calling area may be expanded by as much as an order of magnitude during temperature inversions in the evening and night (Larom et al, 1997). Preliminary results from our recent work with forest elephants suggest that powerful forest elephant calls travel roughly the same distances through the dense forest. The fact that elephant calls can travel several kilometers enables elephant societies to coordinate movements over large areas.
