acoustic communication

Acoustic (that is, sound) signals are omni directional (i.e. they travel in all directions) and can be broadcast to a large audience of intended and unintended listeners, including those in view and those hidden from view. Being short-lived and deliberate, acoustic signals are useful for giving information about an immediate situation, rather than about a constant state. Through reflection, refraction and absorption, acoustic signals are degraded by the environment in ways that are often very much greater for high frequency sounds than for very low frequency sounds. Elephants are specialists in the production of low frequency sound and in the use of long-distance communication. Check out some good examples on acoustic communication by elephants in article "What Elephant Calls Mean: A User's Guide" published by National Geographic in 2014, based on the work of ElephantVoices.

The range of sounds elephants produce

African elephants produce a broad range of sounds from very low frequency Rumbles to higher frequency Snorts, Barks, Roars, Cries and other idiosyncratic sounds. The most frequently used type of call is the very low frequency Rumble. You can search for, listen to and read about numerous calls and other sounds made by elephants on The Elephant Ethogram: A

Like all highly social mammals elephants have a well-developed system of communication that makes use of all of their senses - hearing, smell, vision and touch - including an exceptional ability to detect vibrations.

Acoustic communication takes a look at sound production and hearing in elephants; chemical communication explains how elephants use various secretions and their acute sense of smell to communicate; visual communication looks at how elephants make use of postures and displays and their sense of sight in communication; tactile communication describes how elephants make use of their sense of touch to communicate.

At one end of the spectrum elephants communicate by rubbing their bodies against one another, at the other end they may respond by moving toward the sounds of other elephants calling, perhaps 10 kilometers away. They convey information about their physiological (e.g. sexual/hormonal, body condition, identity) and emotional state (e.g. whether they are fearful, playful, joyful, angry, excited) as well as communicating specific "statements" about their intentions or desires. In this section we look at how elephants use the different pathways of communication and the actual mechanics of communicating.
