The upstairs kids are making noise; smart parents teach their children this way.
2025-11-04
My son went to bed very early when he was little, and he was a light sleeper; the slightest noise would wake him up and he would cry. I always taught him that when he played at home, he shouldn't make any loud noises on the floor. I suggested it might be the kids upstairs having class, and then I told him: "So when you play at home, you shouldn't..."

Netizen 5: I don't know what you guys are thinking. No one lives downstairs, but I don't jump rope upstairs either. Firstly, my house is small, and secondly, my child is already 1.83 meters tall and weighs over 200 pounds, so I'm afraid the building will collapse if he jumps. But my child really needs exercise. In the past two years, he has lost 30 pounds by jumping rope, and all his fat has...

I. Analysis of Noise Issues in Older Communities External Noise Intrusion: Traffic noise: Buildings facing the street are disturbed by traffic and horn noise (60-80 decibels); Commercial noise: Restaurants on the ground floor, square dancing, and other mid-to-high frequency noises have strong penetrating power. Internal Noise Transmission: Poor floor insulation: Footsteps and furniture...
How many people across the country are being disturbed by noise?
2025-11-04
My upstairs neighbors have been disturbing the peace every single day since the Lunar New Year. They are an elderly couple. Because of the pandemic, everyone is unable to work normally. I'm a third-year university student, and I can't go to school either, so I'm studying for my postgraduate entrance exam at home. But even listening to music with headphones on...

Remember: A 5mm gap can ruin the soundproofing of an entire wall! Flooring: Laying a large area of carpet, especially with a thick sound-absorbing mat, can significantly absorb mid-to-high frequency noises and vibrations such as footsteps and dragging objects. These are natural sound absorbers, reducing sound reflection and reverberation in the room, making the space feel more spacious...

Residents told reporters that the white noise during the day can somewhat mask the noise, but the worst part is at night when it becomes exceptionally clear, spreading throughout the entire building. What they find most unbearable is that the noise is only a small fraction of the power of the vibration device.

A survey of residents in several communities showed that after installing ventilated and soundproof windows, over 80% of residents reported a significant reduction in the negative impact of cicada and bird sounds on their lives during the summer, and a substantial improvement in their sleep quality at night. When choosing a place to live, sound insulation is particularly important, and...

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...
Enjoy the coolness: A complete guide to reducing noise from home air conditioners in hot weather
2025-11-04
When outdoor temperatures soar and air conditioners are running at full throttle, the annoying buzzing, sharp airflow sounds, and compressor vibrations quietly intrude into living spaces. This persistent low-frequency noise not only disrupts sleep but also triggers irritability-studies show that prolonged exposure to nighttime noise levels above 45 decibels can reduce deep sleep time...

The main manifestations of sensitivity include: aversion, irritability, low mood, fear of specific sounds, and amplified hearing of certain sensitive sounds. It is often accompanied by tension and anxiety. Physical fatigue and sleep disturbances are symptoms of neurasthenia induced by sensitivity. Humans are naturally inclined to seek advantage and avoid harm, and are inherently averse to...
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...

The draft for public comment proposes that residential communities should, in principle, meet the noise limits required by their respective acoustic functional zones. For noise disturbances caused by daily life within residential communities, community residents' committees, owners' committees, and property management companies should promptly intervene and mediate; the draft also encourages...

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...

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...
