They found that differences in hearing among different populations are largely caused by a combination of factors including population, environment, and language. However, it is currently unclear whether this is due to the overall influence of the environment on the human body, or to long-term adaptation to different soundscapes, noise levels, or exposure to pollution. People living at high...

However, previously, due to the lack of a closed-loop legal system-that is, the absence of laws and regulations protecting the entire construction process, including planning, design, construction, and sales, such as prior disclosure, in-process supervision, and post-construction penalties-it was difficult to clearly define and hold accountable those responsible even if the design or...

Xiao Zhou said he wasn't an unreasonable person; some noise was unavoidable since they lived in the same building. However, the noise from upstairs was having a huge impact on his family's life-the children were frequently woken up and cried; his father-in-law and mother-in-law weren't getting enough rest and were physically exhausted; and he and his wife were always "on edge."
What are the application scenarios for matrix silencers?
2025-11-04
Matrix mufflers can be used in vehicle exhaust systems or as part of sound barriers to absorb and attenuate noise, improving noise pollution from transportation. In the future, matrix mufflers will not only create quieter living and working environments but will also promote noise control and public safety globally...

Just as white light mixes with all colors of light, white noise contains all frequencies audible to the human ear (20~20000Hz), forming a uniform and stable sound wave. • White noise: like the sound of an untuned radio, suitable for blocking high-frequency noise (such as talking). Falling asleep 38% faster: A New York University study shows that white noise can shorten the time it takes for...
Is it worth selling a school district property because of noise from upstairs neighbors?
2025-11-04
Later, I became increasingly concerned about this issue and noticed noise from other people's homes. There's a child downstairs, around four years old, who cries every day, especially at night, not sleeping until midnight, and the parents just play with him... When I got really annoyed, I stomped my feet, and it had some effect. These are all common problems; as ordinary people, we can't...
Analysis of the Necessity and Significance of Airport Noise Control
2025-11-04
Noise levels in some areas surrounding my country's airports have consistently exceeded standards, necessitating systematic governance to reduce the burden on public health. Digital governance: The integration of noise data with smart airport management platforms provides a model for refined urban governance. Through policy guidance and technological empowerment, my country is expected to...

Mass Law: The higher the density of a single-layer material (e.g., tempered glass > ordinary glass), the better the sound insulation. Resonance Control: Laminated structures can disperse sound wave energy (double-glazed/laminated glass is more effective than single-layer glass). Sealing System: 90% of sound insulation failures originate from gaps (actual measurements show that a 1mm gap...
What can be done if commercial operations in a residential building cause noise pollution?
2025-11-04
In commercial operations, operators and managers of equipment and facilities that may generate environmental noise pollution, such as air conditioners and cooling towers, must take measures to ensure that boundary noise does not exceed the national environmental noise emission standards. There are also ways to achieve the best of both worlds; for example, shops are now set up on the perimeter...
How terrifying are people who lack "noise awareness" when it comes to original content?
2025-11-04
But what's truly frightening is that in my company, there are two middle-aged women in their forties who are just coasting along, and a group of burly men having a meal at a restaurant. Is it more frightening to have people who are noise-conscious but still create noise? This is something worth considering...

Ventilation and soundproof windows play a crucial role in healthy housing, perfectly integrating ventilation and sound insulation to create a more comfortable and healthy living environment for residents. In summary, ventilation and soundproof windows improve indoor air quality, reduce noise pollution, save energy, enhance living comfort, and...

Traditional soundproof windows, tightly sealed like "sealed containers," sacrifice fresh air and natural ventilation; while ordinary open windows allow high-decibel noise to penetrate unimpeded-a peaceful life and healthy breathing seem to be mutually exclusive urban luxuries. The inner layer of glass often uses professional sound-insulating laminated glass (with a high-damping PVB...

It wasn't just the sound of the mahjong machine; because they were playing mahjong, there were many people in the house, talking, moving tables and chairs, and they were all from the countryside. Later, the noise did decrease a lot. I went to visit them and found two layers of plush cushions on their balcony, with the mahjong machine on top. The old man said it belonged to his daughter...
Government and businesses join forces to solve traffic noise pollution problems
2025-11-04
According to a report by Guangdong Litchi.com, noise levels in the residential complex exceeded 60 decibels even with windows closed, severely impacting residents' quality of life. Sanyuan Environment participated in the production of several model apartments with different designs in September. This project represents a strong collaboration between the government, the developer, and Sanyuan...
Enjoy a peaceful journey: Sanyuan Environment solves the problem of highway noise control
2025-11-04
Sichuan Sanyuan Environmental Management Co., Ltd., deeply rooted in the field of noise control, has developed a comprehensive management model combining "sound barriers + soundproof windows," effectively solving the problem of noise pollution from highways. Technical principle: Sanyuan Environment's ventilated soundproof windows consist of a system of soundproof windows and a sound-insulating...

A 1-decibel increase in bedroom noise levels at night may mean a 3% increase in the risk of cardiovascular disease; persistent footsteps from upstairs can cause a 10% depreciation in property value... This "invisible killer" of noise pollution is being incorporated into the national mandatory governance framework. A study by the Beijing Center for Disease Control and Prevention shows that for...
Why is the noise always coming from upstairs? An industry insider reveals the truth!
2025-11-04
Although there are national sound insulation standards, they are not included in the acceptance criteria for completed residential buildings, and this is not listed on the building certificate. Many developers only use sound insulation standards when applying for green building or healthy building certifications. Even more troublesome is that, from what I understand, if you've already...

On the one hand, due to past considerations of construction cost, the requirements for residential acoustic environment indicators were relatively low. Furthermore, developers and design units had limited understanding of sound insulation and noise reduction, resulting in a long-standing low quality of residential acoustic environment in my country. On the other hand, my country's noise and...

A smart solution called "ventilated and soundproof windows" is quietly breaking this deadlock and writing a new chapter in urban noise control. Policy support is transforming cost from a "pain point" to a "highlight." Although the unit price is higher than ordinary windows (due to customized design), many local governments have included it in their public welfare projects: Guangzhou's Renmin...
