AbstractThe mechanisms of the reception and transmission of an acoustic signal in birds have been studied. For this, the mechanisms of acoustic isolation in birds have been analyzed, the construction of distress and alarm signals in various bird species has been studied, and the variation of the signal to ensure individuality within the boundaries of the species signal has been considered. It was found that all mechanisms are provided by the temporal discreteness of the signal, which evolutionarily comes from a single-frequency signal, which is shown using the syrinx denervation technique. The study of the nervous activity of the primary auditory nuclei of birds showed that the auditory system of birds is adapted to the analysis of strict temporal discreteness of acoustic signals. To confirm the functionality of the temporal discreteness of acoustic signals in the life of birds, a computer program based on the principles of the construction of natural distress signals for birds has been created for a digital, electronic-acoustic synthesizer of repellent signals to control bird behavior. As a result, it became possible to create a universal signal for all bird species, as well as a multiplicity of signal combinations and their random reproduction in time, so that birds do not get used to the synthesized signal of the repellent.
