The passage discusses the issue of noise pollution in China and new technologies being implemented to mitigate its impact on residents. According to data from the national environmental complaints and reporting management platform, from January to August of this year, there were a total of 167,327 complaints and reports received, with 99,807 related to noise pollution, accounting for 59.6% of all complaints. This indicates that noise pollution is a significant environmental issue affecting residents’ quality of life.
To address this problem, new technologies are being introduced to reduce noise pollution, particularly around construction sites. In one example, a big balloon was seen covering a construction site in Beijing’s Xicheng district. This balloon, or base pit air membrane, is made of high-strength polyester fiber material, measuring 144 meters long and 74 meters wide, covering an area equivalent to 1.4 standard football fields. By enclosing the construction machinery in a sealed space, the noise generated during construction is significantly reduced, minimizing its impact on the surrounding environment. According to nearby residents, the noise levels have dropped dramatically, with sound levels measured at only 60 decibels when windows are open, which includes the background noise from passing vehicles. The Beijing Municipal Commission of Urban Management and Construction stated that the use of this air membrane has reduced noise pollution by 80% and dust pollution by 90%.
Another example of noise pollution mitigation technology is the smart square dance system installed in Chengdu’s People’s Park. This system uses directional sound technology to control the sound within a fixed range, reducing the noise that could disturb residents beyond that range. Square dance enthusiasts no longer have to worry about disturbing the peace with loud music, as they previously faced complaints and were asked not to dance in the park. Now, with the smart square dance system in place, they can enjoy their activity without causing noise pollution.
In addition to new technologies, the Chinese government is encouraging the use of smart monitoring systems to enhance noise pollution control. The Ministry of Ecology and Environment has set a goal for all cities above the prefecture level to achieve automatic monitoring of functional area sound environment quality by January 1, 2025. Shenzhen, for instance, has implemented a remote monitoring and non-contact law enforcement system that can obtain real-time data on construction noise and particulate matter pollution. This system uses artificial intelligence technology to automatically identify and remotely stop construction activities that violate noise pollution regulations. Once identified, the system sends out a warning message, and if the violation continues, environmental protection officers are notified to take immediate action.
The introduction of smart monitoring systems, such as the noise map in Suzhou, enables authorities to precisely identify and address noise pollution sources. The noise map can automatically recognize various types of sounds and trigger alerts when noise levels exceed acceptable limits. Through the use of information technology and smart monitoring, law enforcement agencies can continuously monitor noise pollution and display the results dynamically on a map.
The Chinese government is committed to utilizing new technologies and innovative management strategies to address noise pollution effectively. By promoting the use of smart monitoring systems and noise maps, the government aims to explore social co-governance and take decisive action to solve noise pollution problems that affect residents’ daily lives. The Ministry of Ecology and Environment is determined to tackle the issue of noise pollution by encouraging technological innovation and exploring social co-governance to create a quieter living environment for the Chinese people.
