The Soundproofing Secrets of a Window: Ensuring Uninterrupted Deep Sleep
When noise becomes an invisible threat to daily life. Noise pollution in modern cities has emerged as a significant health hazard. The World Health Organization (WHO) indicates that prolonged exposure to noise levels above 55 decibels (dB) increases the risk of cardiovascular diseases. In the face of noise challenges, a high-quality soundproof window is not only an upgrade for the home but also a necessity for safeguarding health. The Hidden Hazards of Noise – From Hearing to Systemic Chain Reactions ① The Three Major Sources of Noise: Traffic noise: Noise peaks on urban main roads can reach 85 dB, equivalent to being constantly exposed to the environment of a chainsaw in operation. High-frequency tire friction and low-frequency engine roaring form a compound disturbance to human hearing. Industrial noise: Low-frequency noise (e.g., 500Hz band) generated by factory machinery has strong penetration. Long-term exposure to this environment can easily lead to headaches, insomnia, and other neurological symptoms. Lifestyle noise: Medium to high-frequency noises such as square dancing speakers (90 dB) and renovation drills (110 dB) directly impact the eardrum, causing distraction and emotional agitation. ② The Physiological Impact Chain of Noise Hearing damage: Continuous exposure to environments above 90 dB can lead......
