Site found that giraffes manage to publish some sounds! Giraffes considered dumb. They say they have too long neck. And through it impossible to miss enough air to publish a distinct sound - like a "b-uh-uh, m-uh-e or i-ho-ho. Giraffes, of course, snort. But they do nostrils. What can not be considered a characteristic sound.





Some biologists, however, believed that giraffes can generate infrasound - low frequency vibration that the human ear does not catch. Thanks to them and exchange signals.

To understand the mysteries of the long-necked audio Angela took Stoger from the University of Vienna, which has made more than a thousand records, placing microphones among the giraffes. No infrasound researcher did not identify. But she heard other sounds, as it turned out, long-necked still publish.

Giraffes snorts - emit a kind of bass "x-s-s' at a frequency of 92 hertz, discernable by the human ear. These "X-s-s" are the short and long, louder and quieter, with variations. According to Angela, giraffes express their emotions.
