Listen to the sound of ultrasonic killing rats.

Ultrasonic waves are sound waves beyond the audible frequency of human beings. How can I listen to the audition? How powerful (range) can you kill mice? It's to drive away rats. Ultrasonic waves that can kill mice instantly (mice can run) may also make you faint instantly.

The auditory system of rats is between 200 Hz and 90000 Hz (foreign references: Fay 1988, Warfield 1973, the nature of sound).

If powerful high-power ultrasonic pulses can be used to effectively disturb and stimulate the auditory system of mice, they will feel unbearable, panic, loss of appetite, escape and even convulsions, so as to achieve the purpose of expelling mice from their range of activities.

Animals such as mice and bats communicate through ultrasonic waves. The mouse's auditory system is very developed, and it is very sensitive to ultrasonic waves, and it can also judge the source of sound in the dark. Young rats can emit 30-50kHz ultrasonic waves when they are threatened.

When they don't open their eyes, they can return to their nests by ultrasonic waves and echoes (foreign references: Allin and Anks 197 1: carden and Hofer 1992). Adult rats can send out an ultrasonic wave to call for help in an emergency, and they can also send out ultrasonic waves to express happiness during mating. It can be said that ultrasound is the language of mice.
