Sažetak
Sometimes it is necessary to chase certain animals from places important to men. One among many methods is the acoustical method – sound, particularly ultrasound, is used to accomplish enough irritation in animals to chase them. Some mammals are more suitable for this method according to their good hearing in the ultrasound range [1]. As the absorption of sound in air increases with frequencies, low ultrasound frequencies should be used. The influence of experimental ultrasound signals on the appearances of irritation in rats and dogs was measured. The first test signal was a simple sine, and the second a swept sine. In both experiments animal irritation was obtained at 10 dB less sound pressure level with the swept sine than with the sine signal.
