Interpretation: Noise has many causes. Removing environmental noise primarily aims to mitigate the impact of uncontrollable factors, such as thunder, rain, and wind. All environmental noise that is difficult to generate or resolve through human intervention is excluded from regulation. ① Let's look at the first change: This revision of the Noise Law...
What are the classifications and uses of industrial soundproof enclosures?
2025-11-04
Soundproof enclosures absorb, reflect, and isolate noise through specific structures and materials, providing a relatively quiet working environment. These materials absorb noise energy and reduce noise reflection and propagation. In short, industrial soundproof enclosures are an important noise control device that can reduce noise propagation, protect the working environment, and meet...

The most complained-about environmental problem in 2023 was actually this!
2025-11-04
The report points out that there are three main reasons for the increasing number of noise complaints: First, with the rapid development of urban construction, population density has increased, the number of motor vehicles has increased, and industrial, commercial, and construction activities have become more frequent. In addition, residential areas are often mixed with commercial and...

Impact noises (such as footsteps or falling objects): These are caused by vibrations from objects hitting floors or walls, transmitted through the building structure, and are a current challenge for residential sound insulation. Direct transmission: Vibrations travel through floors → walls → ceiling → indoor air, creating audible noise. Door and window gaps: Poorly sealed sliding windows and...
How to reduce industrial noise in petrochemical plants?
2025-11-04
For noise sources such as production and conveying equipment, technical measures such as soundproof enclosures, vibration isolation devices, and silencers can be used to reduce noise propagation and radiation. In addition to controlling noise sources, noise protection equipment, such as earplugs and noise-canceling helmets, should be provided for petrochemical plant workers to reduce the...

Building upon traditional soundproof windows, the advent of ventilated soundproof windows represents a significant upgrade, resolving the issues of traditional windows failing to provide adequate sound insulation when open and lacking ventilation when closed. The application of ventilated soundproof windows also has practical implications, as traffic noise pollution is only one aspect; other...
The principle of no-fault liability applies to the prevention and control of noise pollution.
2025-11-04
In disputes concerning tort liability caused by excessive noise, even if the responsible party is not at fault, as long as a tort exists and there is a causal relationship between the tort and the damage, the responsible party should bear the liability. However, it should be noted that although the principle of no-fault liability applies, the tortfeasor can still seek redress based on legal...

Recently, the noise online team of the company's Technology R&D Department proposed a "four-dimensional model" solution. This solution empowers the noise mapping system through a full-chain process of "perception, analysis, decision-making, and feedback," providing a replicable and scalable benchmark for urban sound environment management. Sanyuan Environment has innovatively built a...
What are some noise reduction measures for industrial diesel generator sets?
2025-11-04
Soundproof enclosure: Installing a soundproof enclosure around the diesel engine unit can effectively reduce noise transmission. Optimized intake and exhaust system: By improving the design of the intake and exhaust systems to ensure smooth airflow, noise caused by airflow turbulence can be reduced. Through reasonable design, sound insulation and vibration reduction measures, acoustic...
