The Language of Some Wild Predators in Soundgrams (Spectrograms)
V. Alexandrova, Y. Kostov
Abstract: This article describes the graphic records of sounds, emitted by some wild predators, the coded signal and its constituent parts are visualized by electronic equipment. The signal, emitted by the animals, was characterized by amplitude and frequency modulation, phase, pause and oscilloscopic form in a graphic curve. The records showed that the signals were modulated in the form of a code of sound vibrations depending on the animal species.
