Amongst lesser-known facts, is that, Elephants are adapted to send & receive, powerful low frequency vocalizations using their feet, that carry over long distances.
These low frequency vocalizations called ‘rumbles’ are Seismic vibrations that travel through the ground. This ability to hear infrasonic sounds can help explain how Elephants know where to go when they navigate vast distances in search of water.
Rumbles are low frequency infrasonic components, which are below the level of human hearing.
Rumbles can easily travel distances of 6 kilometres & beyond which helps elephants coordinate among themselves & navigate vast distances.
