PN-1000 Environmental Noise Monitoring Solution
Expand the objects and scope of application of prevention and control; strengthen planning prevention and control, and highlight source governance; emphasize government responsibilities and clarify departmental responsibilities; improve various noise management measures; strengthen social co-governance and improve noise prevention and control mechanisms; strengthen punishment for violations and improve legal responsibilities.
"14th Five-Year Plan for Ecological Environment Monitoring" - Ministry of Ecology and EnvironmentImprove acoustic environment monitoring. Standardize the setting of acoustic environment quality monitoring networks, and by the end of 2025, cities at the prefecture level and above will fully realize automatic monitoring of acoustic environment quality in functional areas and network with the state. Stricten the performance and quality requirements of noise monitoring instruments, strictly control the quality control of the monitoring process, and improve the accuracy of monitoring results.
"14th Five-Year Plan for Noise Pollution Prevention and Control" - Ministry of Ecology and EnvironmentThrough the implementation of noise pollution prevention and control actions, the pollution status of key noise sources is basically grasped. Key noise discharge units should carry out automatic noise monitoring in accordance with the law and network with the monitoring equipment of the ecological and environmental authorities in a timely manner. By 2025, the nighttime compliance rate of the national acoustic environment functional area will reach 85%.
As the second largest "invisible killer" after air pollution, noise pollution is affecting the living environment in various forms.
According to the statistics of the "China Environmental Noise Pollution Prevention and Control Report" released by China every year, in 2021 alone, the citizen service hotline and various departments accepted more than 4.01 million noise complaints and reports, of which domestic noise complaints and reports were the most.
The national ecological environment new housing complaint and report management platform has received more than 450,000 complaints. Noise nuisance accounted for 45% of them, an increase of 3.8 percentage points year-on-year, ranking second among all environmental pollution factors, second only to air pollution.
The acoustic environment pollution is becoming more and more serious, resulting in traditional manual monitoring and handheld instrument monitoring can no longer meet the development demands of ecological network construction at this stage. The development and construction of intelligent, all-weather noise maps and networked noise online monitoring systems will help promote the level of noise pollution prevention and control.
-
Fixed-point monitoring
Select one to several monitoring points that can reflect the quality characteristics of the acoustic environment in various functional areas, and carry out long-term fixed-point monitoring, and the position and height of each measurement should remain unchanged. -
Census monitoring
The functional area of a certain sound environment to be censed and monitored is divided into multiple square squares of equal size, and the grid should completely cover the area to be censed, and the total number of effective grids should be more than 100.
PN-1000 environmental noise automatic monitor is mainly composed of noise monitoring module, independent power supply module, meteorological six-parameter module, traffic flow monitoring module (optional), outdoor LED screen (optional), video surveillance (optional), environmental noise monitoring platform, database, etc. It is an automatic monitoring equipment integrating high-performance real-time online monitoring of noise, data collection and transmission.
