An international team of voice researchers and cognitive biologists provides new insights into the production of elephant communication.
The so-called "infrasounds", i.e. sounds with pitches below the range of human hearing, are found to be produced with the same physical mechanism as human speech or singing.
Elephants can communicate using very low frequency sounds, with pitches below the range of human hearing. These low-frequency sounds, termed "infrasounds," can travel several kilometers, and provide elephants with a "private" communication channel that plays an important role in elephants' complex social life.
Their frequencies are as low as the lowest notes of a pipe organ.
