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 2-3 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 are in a noisy environment for a long period of time will be more aggressive in their future personalities.
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 Standards for Acoustic Emissions from 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 doors should not be less than 30dB. 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.
