Mystery of
elephant infrasounds revealed
"Science":
The physics of making very low sounds
In the
current edition of "Science", an international team of voice
researchers and cognitive biologists led by Christian Herbst, Angela Stoeger
and Tecumseh Fitch, 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.
