Problems solved by technology

However, although the frequency of the ultrasonic waves sent by the current ultrasonic rat repellent belongs to ultrasonic waves, its sound wave characteristics are simple mechanical square waves, and the sound wave parameters are all artificially designed, mostly mechanical constant frequency or simple frequency sweep ultrasonic waves, while It is far from the complex ultrasonic wave that contains certain communication information for mice, which leads to a very low effect of repelling mice
This type of product has not been fundamentally updated for a long time, which has hindered the development of the ultrasonic mouse repellent industry, and even began to shrink and decline.

Embodiment 1

[0016] A method of using ultrasonic waves to repel mice, the method comprises the following steps:

[0017] 1) Adaptive feeding of adult Rattus norvegicus for more than one week, record the ultrasonic waves sent by the rats when they are shocked, frightened and painful in a soundproof room with a mouse ultrasonic recording device to obtain a recording file;

[0018] 2) Convert the recording file obtained in step 1) into a digitized audio file, and select sound waves with clear sound wave structure, high sound intensity (sound intensity not less than 30dB), and good continuity (continuous duration not less than 0.1ms), and carry out Background noise reduction, sound wave enhancement, serial grouping, etc. edited to obtain the edited ultrasonic audio file, the edited ultrasonic parameters are as follows: main frequency 20.0 ~ 22.2kHz, bandwidth 3.0 ~ 4.0kHz, base frequency 18.3 ~ 24.0kHz, start frequency 24~18kHz, the end frequency is 23~17kHz, the ultrasonic frequency changes f...

Abstract

The invention discloses a method for repelling mice by utilizing ultrasonic wave. Based on the optimized spontaneous ultrasonic wave of mice, the parameters of the edited ultrasonic wave are as follows: main frequency is 20.0-22.2 kHz, the bandwidth is 3.0-4.0 kHz, the fundamental frequency is 18.3-24.0 kHz, the starting frequency is 24-18 kHz, the end frequency is 23-17 kHz, the frequency of the ultrasonic wave is changed in a manner of being high in front part and low in rear part, and the time interval of the ultrasonic wave in each section is 0.1-2.0ms. The mouse repelling effect can be remarkably promoted, and the method has great help on improving the existing ultrasonic wave mouse repelling device, winning the trust of consumers, and obtaining market shares.

Description

[0001] Technical field: [0002] The invention relates to the technical field of ultrasonic mouse repelling, in particular to a method for using ultrasonic waves to repel mice. [0003] Background technique: [0004] The harm of rodents to humans has been enduring and has become one of the most important biological disasters. Rats not only steal food and gnaw objects, but also spread hundreds of diseases, causing serious harm to human production and life. Common control measures mainly include chemical killing, physical control and biological control, each of which has its own advantages and disadvantages, as well as the scope of application. Among them, physical prevention and control has more potential, and the methods that are both environmentally safe, hygienic and humane are more likely to be accepted by the public. Utilizing that rats have the ability of ultrasonic communication, but human ears cannot hear ultrasonic waves, people have developed a variety of ultrasonic ...
