Hmm ... Scientists have found that giraffes are able to hem!

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.
