The noise reduction "double artifact" makes the square dance no longer disturb the people

In Jiangyi Park Binjiang District, there are various rhythmic music sounds from 7 to 9 pm every night. At the same time, accompanied by neat dance steps and simple actions. Although there is no border of music, the volume has the boundary. Once the volume of music exceeds this boundary, the smart music becomes the noise of disturbing the people. The residents around the park have been tortured by the square dance noise for a long time, and the contradiction between the two sides has gradually deepened. Because of this, the noise disturbing the people in Jiangyi Park, which often caused the police to call the police. Every time the police arrived at the scene, letting the uncle and the aunts lighter, they cooperated, but as long as the police walked away, they immediately opened their voice.

How can I stop the dance of the square dance and disturb the people, and at the same time do not deprive my uncle and aunt pursuing the right to pursue health and happiness. Considering that the prerequisite for preventing and controlling the dance of the square is the first to solve two problems: one is that the sound of sound is a intuitive feeling of human beings. Everyone's patience for sounds is different. How to quantify and delineate noise? The second is that the police force is limited. How to achieve real -time monitoring of noise, and reminds on -site anytime, anywhere? Deng Zhiping, a police officer of the comprehensive command room, took the initiative to contact the science and technology company in the jurisdiction, trying to resolve the dance noise disputes of the square through science and technology empowerment and innovation leadership, and do their best to reduce control of such alert conditions to drive the society to form a harmonious, civilized and healthy square. culture.

So with the efforts of the police officers of the Changhe Police Station, two noise -proof "artifacts" appeared.

"The Changhe Police Station reminds you that your volume has exceeded the standard, please reduce the volume." Just when the uncle and the aunts were soaked and immersed in the dance, a voice reminder suddenly sounded. At the same time The pillars are equipped with an electronic display in a 2.5 -meter -high position in the pillar. The number is constantly beating in the screen, reminding the sound of the sound to sound red. An old man responsible for tuning at the scene looked up at the display screen, carefully dial the volume, and the red figures changed back to green, and the reminder sound stopped abruptly. Uncle and aunts continue their health and happiness. This artifact on the pillars and real -time monitoring on -site volume is a specially customized smart decibel device specially customized in the Changhe Police Station in conjunction with the Square Dance Point. The sensitivity to environmental noise collection is very high, and the error is only 1DB.

Intelligent decibel meters can be calculated on the on -site environmental noise, and displayed on the two -color LED dot matrix display. When the environmental noise exceeds the alarm threshold, the decibel value on the display screen is red, and the other normal situation is displayed. Voice reminder, the content of the broadcast can be set on demand. We have also set up the "Regulations on the Prevention and Control of Environmental Noise Pollution of the People's Republic of China" and "Hangzhou Environmental Noise Management Regulations", which reminded as we carried out publicity. The decibel value can be transmitted back to the Changhe Police Station's integrated command room intelligent decibel device management platform. When the number of live voice prompts is more than 3 times, the management platform trigger the early warning. It has not been rectified in time, and then command and dispatch the police to rush to the scene to deal with it.

There is a 1.5 -meter -high box on the side of the square, which is particularly noticeable. It is another noise -proof "artifact" -the filter treasure box. The box is customized according to the needs of the police. Putting the speakers, the inner wall of the box is covered with three or four centimeters thick soundproof cotton, and the outside is attached to the National Anti -Fraud Center APP QR code, relevant laws and regulations related to noise prevention, and the number of contacts in the police station. Anti -fraud propaganda, no mistake. The filtering treasure box is directed to a specific area, which means that the music of the square dance is transmitted to the dancing crowd through most of the boxes. The effect is obvious.

Police Deng Zhiping said: "There are several waves of dances in this square. Previously, due to the poor volume, the sound of music was very large, resulting in a vicious circle. Everyone's music was bigger and bigger. Music and disputes are getting deeper and deeper, and several times have almost triggered physical conflicts. The noise alarm is also constantly on both ends. Since mid -July this year, this smart decibel device has been installed. Several dance teams can master the volume in real time. We are also very conscious and can actively control the volume. After all, convenience with others is convenient and convenient. Such square dance disputes have never happened, and the noise police situation has been effectively controlled. It's. "

The dancing uncle and aunt also said: "The box of this speaker is very interesting. The volume of different sides is obvious. It is enough to listen to us. The common people, this is too practical. "

In the next step, the Changhe Police Station will continue to improve the two major noise -proof "artifacts" according to the actual effect, and promote and use it in multiple square dance gathers, trying to achieve the goal of "dancing dancing with grace, law enforcement with temperature".
