First, privately to find the square dance organizers to reason, emotion, to obtain the understanding of the elderly.
Because the old people dancing is a low-cost fitness way to get big benefits, they can exercise and socialize, so they are y loved by the older women. When they are excited to jump up and down, if you hard to stop, in the face of no one may listen to you, the result of a nose. As the saying goes, "The thief is the first to catch the king." Should change the strategy, find the organizer of the square dance, give her the importance of the school, explaining the school is for the motherland to cultivate talents of the sanctuary, the campus is supposed to be pure, quiet place, senior high school and is a student for many years to study the key moment of further education, our families have children to study in school, perhaps at the moment, no children on the senior high school, but we have to be more than a heart, is not it? Originally, square dancing is a good thing, everyone can have their own hobbies, but if because of their own hobbies and affect the normal teaching order of the school, affecting the children's college entrance exams, which determines the fate of the future of the big event, we can not bear it in the heart? This is the heart, persuade, believe that the organizer will understand, after all, the heart is meat long well. Once the organizer figured it out, she would naturally find a way to remove the square dance team from the activities near the campus.
Second, the relevant government departments to solve the problem is more convincing.
One is to fundamentally solve the problem of fitness places for the elderly. This requires the government planning department to set aside sufficient space for civic activities in urban planning to solve the fitness problem of the elderly. Secondly, it is necessary for the community, streets and such grass-roots organizations to play a coordinating role to balance the demands of all parties.
Thirdly, from the perspective of environmental protection, the relevant government departments organize free health training courses for the elderly and invite famous medical doctors, nutritionists, sports health professionals to speak to the elderly about exercise and health care knowledge.
First of all, sound pollution is harmful to the body. China's legal provisions: residential outdoor noise is allowed to 40 decibels night day 50 decibels, and the square dance sound equipment does not not exceed the decibel. These super-decibel sound is noise, serious harm to people's bodies, so that people easily feel fatigue, negative emotions, and even cause diseases, such as hearing damage, the nervous system, the cardiovascular system, the endocrine system, the digestive system, as well as vision, intelligence and so on have different degrees of impact. For example, our digestive system, strong noise will make people appear digestive dysfunction, gastric dysfunction, stomach acid reduction, loss of appetite and so on. In short, strong noise will lead to a series of physiological and pathological changes in the human body. Some people have worked in the noise up to 95 decibels in the environment of the 202 people have conducted a survey, dizziness accounted for 39%, insomnia accounted for 32%, headache accounted for 27%, stomach pain accounted for 27%, panic accounted for 27%, memory loss accounted for 27%, distracted accounted for 22%, poor appetite accounted for 18%, high blood pressure accounted for 12%. You see, originally dancing is for health, but the result is harmful to the body, the loss is not worth it. Therefore, we can not take the strong noise lightly, we should take measures to prevent it.
Secondly, we should talk about how to protect the human knee. Because the knee is more prone to injury. Climbing mountains and stairs can hurt the knees, so people will try to minimize the bending of the knees when walking, to reduce the pressure on them. When dancing, the knees are subjected to 0.6-1.5 times more pressure than usual. In order to minimize the damage, Western aristocrats dance in the texture of the soft carpet, in the hard concrete floor or tarmac dancing is tantamount to self-harm. A report by the Institute of Human Mechanics and Sports Functions at the University of Manchester in the United Kingdom shows that people who dance for more than an hour a day, after the age of 40, the incidence of knee arthritis, knee joint neuralgia is 48.7% higher than the normal population, respectively, and 76.1%. It can be seen that the elderly over the age of 50 should be even less square dancing.
Third, from the technical problems, the production and sale of directional ultrasonic sound.
I have seen a new audio product in the news - directional ultrasonic sound. Ultrasound itself is directional propagation, ultrasonic sound is to let can't directional audible sound can also directional propagation of a long distance without attenuation, but the other direction almost can't hear the sound. Maritime authorities use this equipment in a few kilometers away from the illegal fishing boats shouting effect is very obvious. If you hang an ultrasonic directional sound on the side of the dance floor, aimed at the dance floor, only the dance floor can hear the music, other places can not hear the sound, it will not disturb the people and will not interfere with student learning. At present, the directional ultrasonic sound has been a domestic product, perhaps a little expensive has not been promoted in the market. Manufacturers should see the square dance this huge potential market, mass production, cost control, the price is set in the ordinary people can accept the range, such as 500 yuan to 1,000 yuan or less, it is entirely possible to promote the open.
All in all, the school is a place for students to learn, square dance participants need to have a basic literacy, can not be too self-centered, need to consider the feelings of students. Of course, it is best not to set up a dance floor near the school, to ensure that the campus is quiet and learning atmosphere, to improve the students' learning efficiency, so that they can be able to flag in the college entrance exams, and get the desired results.
