This is the emission of sonic waves. In principle, they do not differ from those emitted when listening music on a mobile phone, watching TV, hearing voices. But there is a detail — ultrasonic frequency is above 20 kHz, in this particular case, it ranges about 50 kHz. Whereas the range of human hearing is at most up to 20 kHz, on average it does not exceed 18 kHz. In other words, the frequency is 2-3 times higher than that a human can hear. That is the tricky part. And it is not just human but also cats and dogs who will be safe. Within a week of testing PEST VENATOR, the cat remained absolutely indifferent and the ultrasonic sound did not bother it at all. Also, ultrasonic sound is safe for other domestic animals such as hens, cows, and pigs. Therefore, you can safely install an ultrasonic pest repeller in a hen house or standing stall.
