From last year 1 1 month, I came up with the idea of buying a soundproof earmuffs online to help incompetent people concentrate on preparing for exams, such as morning reading. It was not until last night that the boss of the composition network took the time to remit royalties that he could afford to buy tuition-free, living expenses, state grants and precise poverty alleviation funds.
This winter morning, I started the initial work of purchasing. The effective sound insulation function of most sound insulation earmuffs can reduce the noise by about 30 decibels. Although I have studied basic physics in junior and senior high schools, including the teaching content of decibels, the concepts of junior high schools can no longer be compared in depth because of the passage of time and old memories. Similar to the champion Lang Weng Tonghe, we can't "finish half a strong Qing dynasty with a stroke of a pen" and need to learn from the dilemma of the world. Therefore, it is widely beneficial to review and supplement self-training through network means.
In "Baidu knows", the loudness decibels of normal conversation are 40-60, and those below 20 decibels are quiet; The decibel value of the loudness of the whispering sound that couples hear in their ears ranges from 20 to 40, and the value below 15 decibel is "dead silence". Of course, I hope that the loudness of the sound produced by the amplitude of an object is a few stories lower than that naturally heard by Beethoven, and it is best to reach the realm of "sound".
The title and related contents of the document of People's Republic of China (PRC) Environmental Noise Pollution Prevention Law are known and quoted by Baidu. I think it is suitable for the present situation, so I read it word for word.
From the past to the present, occasionally there are road signs prohibiting motor vehicles from passing by the hardened roadside. But I don't understand why people should enjoy such a wide and good road in various non-destructive ways. Only by reading the law can I teach you: it is forbidden because of noise pollution prevention; Because the loudness of motor vehicle engine vibration sound does not meet the requirements stipulated by the competent administrative department for the prevention and control of environmental noise pollution, it is prohibited to use it.
When I was a freshman, I worked in the Ministry of Labor and Health. When I was training with the minister in health district inspection, I put forward the following view: "If a classmate continues to throw garbage provocatively after repeated reminders, he will respond directly to the principal." The minister disagreed with the idea of disturbing the hard-working headmaster and said, "The headmaster has his own things to do. How can he be free?" The freshmen who trained with me echoed: "Everyone else must go to the ordinary court first, and then to the high court. How can you skip class like this? " Although my views are not comprehensive, the ideas in them are not without merit.
Article 61 of Chapter VII of the Law of People's Republic of China (PRC) on the Prevention and Control of Environmental Noise Pollution stipulates:
"Units and individuals that are harmed by environmental noise pollution have the right to require the injurer to eliminate the harm; If losses are caused, compensation shall be made according to law.
Disputes over the liability for compensation and the amount of compensation may be settled through mediation by the competent administrative department of environmental protection or other supervisory and administrative departments and institutions for the prevention and control of environmental noise pollution at the request of the parties concerned; If mediation fails, the parties may bring a lawsuit to the people's court. The parties may also directly bring a suit in a people's court. "
In other words, the parties can either "mediate" and then "sue", or skip the "mediation" layer and directly "sue". This coincides with my view that I skip student subjects and ask the headmaster for help directly. Therefore, "skipping rope" also has its merits.
