How the ultrasonic device works
Ultrasonic devices that repel animals and vermin work by affecting their hearing threshold.
The human hearing system is not able to hear every sound wave. But it can hear the frequency of 20-20000 Hz. Sound waves whose frequency is less than 20 Hz are known as infrasound waves. While waves with a frequency greater than 20,000 Hz are known as ultrasound waves. These waves are widely used in medicine and industry. The hearing threshold of animals and insects is different. In the case of dogs and cats, it is 22-25 Hz, mosquitoes, fleas, flies and cockroaches 44-38 Hz, lizards 60-52 Hz, and mice 60-72 Hz. Repellents can produce frequencies that can be heard by animals and pests. Hearing these waves, animals and vermin cannot stay in the environment and run away quickly.
