SCIENCE

The Claim

Elephants communicate using low-frequency sounds that are often inaudible to humans and can travel long distances, as well as through body language such as ear and trunk movements.

Verified by Lenz ·

The Short Version

This claim is well-supported by peer-reviewed research and reputable science reporting across both its components. Studies published in journals and covered by outlets like Physics World, Science News, and PubMed confirm elephants produce infrasonic vocalizations (typically below 20 Hz) that travel kilometers through air and ground. The body language component — ear flapping and trunk gestures as communicative signals — is corroborated by a 2024 Smithsonian Magazine report citing peer-reviewed research in Communications Biology. The qualifier "often inaudible" accurately reflects that infrasonic components dominate long-range communication.

Caveats

  • Elephant rumbles contain both infrasonic (inaudible) and audible components; humans can hear parts of these calls at closer ranges (up to ~800 meters).
  • Long-distance propagation claims (6–10 km) apply under ideal conditions and vary with habitat, wind, and ground characteristics.
  • Some lower-authority sources in the evidence pool (tourism sites, YouTube videos) should not be relied upon independently, though the core claim is confirmed by higher-quality sources.
