I have to record it myself.
Xiang Han got a patent to drive away mice with dying cries.
After dealing with rats for three years, a citizen of Changsha invented a "weapon" specially for rats. He recorded the mouse's dying cry and then let it out to scare away. This strange trick was patented.
According to the Oriental New Newspaper, 46-year-old Mogaochi has a daughter who is particularly afraid of mice. In order to create a good learning environment for their daughter, the couple often have a rat-catching war. Rat poison and rat trap have been used, but they cannot be completely eliminated.
One day, Momo saw on TV that the mouse was very sensitive to the sound of his companion's death, and once he heard it, he dared not appear in the place where his companion died. It suddenly occurred to him that if the mouse's dying cry was recorded and then released to scare the mouse, could it drive the mouse away?
Come up with something unexpected
So, he bought a mouse from the pet market and came back to do the experiment, but the mouse's cry didn't work on the house mouse. So he came up with another idea and spent a lot of money to buy live mice. He posted reward advertisements everywhere, and a few days later, he finally received thirty or forty rats, large and small.
To ensure the recording effect, he spoke rashly? A big bag of rats went to the recording studio of a local radio station. When he shook the mouse in the studio, the radio staff screamed. After listening to his intention, the staff expressed admiration for Mo's behavior and carefully cooperated with Mo to record the mouse's dying cry.
This time he finally succeeded. As soon as he played the recording, the mouse ran away. Since then, the house has been much quieter. However, a month later, the mouse came back. In the evening, when they heard mice scurrying around the room, the couple quietly pressed the play button of the tape recorder. Soon, the mice were anxious and ran away. From then on, the Morse mouse? It is rare that the electronic mouse repellent he developed has also obtained patent registration.
