New residential buildings utilize a four-pronged noise reduction system: campus noise reduction, building sound insulation, household sound insulation, and indoor sound insulation. This not only optimizes physical space but also represents a necessary innovation to combat noise pollution during urbanization. The campus utilizes micro-topography design (such as earth slopes and soundproof...
Noise-canceling headphones: The hidden risks behind convenience
September-30th-2025
Prolonged use of noise-canceling headphones can cause the brain to "forget" how to filter out noise, especially during adolescence, when the brain's complex auditory processing abilities haven't yet fully matured. When noise-canceling headphones block mid- and low-frequency ambient sounds (such as traffic noise), the superior temporal gyrus, an area responsible for sound processing, becomes...

A 1dB noise level exceeding the standard in a bedroom late at night could increase cardiovascular disease risk by 3%. Long-term noise disturbances from upstairs could cause a 10% depreciation in property value. Noise pollution, this "invisible killer," is being incorporated into the national mandatory governance framework. A Beijing Center for Disease Control and Prevention study found that...
[Environmental Science Popularization] Noise disturbance is illegal, use noise reduction measures!
September-30th-2025
Bars and other businesses operating at night should strictly control their operating hours, install soundproofing pads and windows, and reduce the volume of high-pitched equipment to prevent nighttime disturbances. Businesses should actively participate in noise pollution prevention and control publicity campaigns, reminding customers to avoid noise pollution during dining, leisure,...
