The rapid development of industry and urbanization has inevitably intensified the level of noise pollution.
The noise from various occasions in life has been exhausting. The most direct hazard to humans from noise is hearing impairment, which affects the central nervous system of the brain. It causes headaches, brain swelling, tinnitus, insomnia, fatigue, and memory loss and other symptoms of neurasthenia. The incidence of hypertension, arteriosclerosis, and coronary heart disease is 2 to 3 times higher in those who work in a high-noise environment for a long time than in a low-noise environment. The noise is extremely harmful to the fetus. High-decibel noise can damage the auditory organs of the fetus and can also cause dysfunction of the endocrine glands of pregnant women, leading to miscarriage and premature birth. Studies have shown that children who have been in a noisy environment for a long period of time will be more aggressive in their future.
Today, people are increasingly demanding quality of life and health. The appropriate temperature, security measures, and quietness of the living environment have become an indispensable requirement. In order to control and control noise pollution, the state has promulgated the "Regulations on the Prevention and Control of Environmental Noise Pollution" and the "Sound emission Standards for Social Living Environment" and other regulations. China's "Green Building Evaluation Standard" Section 4.5.3 requires effective noise insulation and noise reduction measures for the building envelope structure, and the sound insulation of the outside window and door must not be less than 30 dB. China's “Design Code for Sound Insulation for Civil Buildings” has set clear sound insulation standards for residential buildings, schools, hospitals, hotels, offices, and commercial buildings. The Shanghai Municipal Government has implemented the "Measures for the Prevention and Control of Noise Pollution in Shanghai's Social Life" starting from March 1, 2013. It has defined the standards for the identification of noise pollution in parks and other public places, noise in residential areas, noise in residential communities, etc.; Sites provide for multi-level prevention and control measures.
In addition to strict control measures for noise pollution by government departments, installation of soundproof doors and windows has become an effective way for people to solve noise problems on their own.
