1/4 cities across the country sleep in noise

Interviewed expert: Li Xiaodong, researcher at the Institute of Acoustics, Chinese Academy of Sciences, “Life Times” (2016th Edition September 09, 09)

A few days ago, the Ministry of Environmental Protection issued the “Report on China’s Environmental Noise Pollution Prevention and Control (2016)” (hereinafter referred to as the “Report”), which disclosed the current status of the urban acoustic environment in 2015. The following three issues are particularly prominent. 


 

1/4城市夜间声测不达标。全国共308个地级及以上城市声环境质量监测显示,夜间噪音达标率远低于白天。而31个省会城市昼间总点次达标率为87.7%,夜间仅为61.8%。“这主要是重型货车造成夜间噪音超标。”中国科学院声学所研究员李晓东解释。 

1/3环境投诉源自噪声。《报告》显示,全国共收到环境噪声投诉35.4万件,占环境投诉总量的35.3%。其中,建筑施工噪声类占50.1%,社会生活噪声类占21.0%。按照经济区域划分,东部地区噪声投诉量占全国59.3%,远高于西部、中部和东北地区。但由于对交通、装修等噪声的取证、处罚难度很大,导致噪声投诉常常不了了之。 

Guiyang is the most “noisy” area.In this survey, Guiyang became the most “noisy” place in the country with an average value of 58.9 decibels, followed by Harbin.Li Xiaodong believes that noise in some cities has been controlled, but development-oriented cities such as Guiyang have neglected the prevention and control of noise pollution in their construction planning. Improper selection of building construction, traffic arteries, and factory locations will also aggravate noise pollution. 
 

对《报告》反映的问题,李晓东认为,主因还是污染治理重视不够。数据显示,2015年,噪声治理施工项目和竣工项目仅占全国老工业环境污染治理项目总数的1.2%和1.3%。全国施工项目本年完成投资合计773.70亿元,其中噪声治理投资为2.79亿元,相较而言,投入少得可怜。尽管各城市对噪声都有规定,如《北京市建设工程施工现场管理办法》规定,在噪声敏感建筑物集中区域内,夜间不得进行产生环境噪声污染的施工作业。因重点工程或者生产工艺要求连续作业的,需要在22时至次日6时期间进行。 
  

But the reality is that the division of powers for noise management by the industry and commerce, urban management, public security agencies and other departments is not clear, which makes the prevention and control of noise pollution unsatisfactory.Improper noise prevention measures, coupled with factors such as social ethics, have made the noise problem worse. 
  

Li Xiaodong said that to control urban noise pollution, we must first set up sound insulation belts between traffic arteries, construction sites and residential areas; secondly, increase vehicle management and limit the passage of noisy vehicles.Li Xiaodong emphasized that once the sound of industrial areas and residential areas exceeds the limit specified in the “Urban Area Environmental Noise Standard”, residents can call 110 to complain.If the noise problem you face is caused by construction on the site, you can first complain to the local environmental monitoring station, and then negotiate with the construction party after the noise measurement, and if necessary, ask the construction party to pay a certain disturbance fee.If the noise reaches the limit standard, it will still affect the lives of residents.Li Xiaodong suggested that you can put green plants with more branches on the windowsill, choose thicker curtains, and wear earplugs when you sleep.
