Elephants are known for their incredible intelligence and ability to communicate with each other. In recent years, researchers have discovered that elephants use infrasound to communicate over long distances.

Infrasound is sound that is below the human hearing range, typically below 20 Hz. Elephants are one of the few animals that can produce infrasonic vocalizations. These vocalizations can travel up to several miles through the air and even farther through the ground.

One study conducted by researchers at the University of Sussex found that elephants in Amboseli National Park in Kenya used infrasound to communicate with each other during fights with other elephant groups. The elephants would produce vocalizations that were below the human hearing range, but were picked up by specialized microphones placed around the park.

The researchers found that the elephants would use these vocalizations to coordinate their movements and communicate with each other. For example, when one group of elephants was separated from the others, it would produce a low rumbling noise that would be picked up by other groups. The other groups would then respond with their own rumbling noises, allowing the separated group to locate them.

Another study conducted by researchers at the University of Tokyo found that elephants also use infrasound to communicate with each other during pregnancy. When pregnant elephants are within hearing range of each other, they will produce low-frequency vocalizations that are believed to be a form of communication about pregnancy status and social relationships.

In addition to using infrasound, elephants also communicate with each other using a variety of other methods. For example, they use body language and visual cues to communicate their intentions and emotions. They also use a variety of vocalizations, including trumpets, barks, and grunts, to communicate with each other.

The ability of elephants to communicate with each other over long distances using infrasound is truly remarkable. It demonstrates the incredible intelligence and sophistication of these gentle giants, and helps us understand more about their behavior and social structures. As we continue to learn more about elephants and their communication methods, we can work towards better understanding and protecting these amazing animals.
