长期在噪声中生活,会使人烦燥不安、听力下降、血压升高,引起心血管、神经以及肠胃等系统疾病,从而危及身体和精神健康。为此,国家制定了《城市区域环境噪声标准》,规定纯居民区内,户外允许噪声级白天为50分贝,夜间40分贝。但实际上,许多地方的超标情况仍然十分严重。
Long-term life in the noise, people will be irritable, hearing loss, high blood pressure, causing cardiovascular, nervous and gastrointestinal diseases, which endanger physical and mental health. To this end, the state has formulated the “Urban Area Environmental Noise Standard,” which stipulates that in the purely residential areas, outdoor noise levels shall be 50 dB during the day and 40 dB at night. However, in fact, the excessive situation in many places is still very serious.
