随着工业和交通的发展,噪声污染日增。大量调研资料表明,噪声对人体的影响是多万面的,例如听力损害(特异性的),对神经、心血管、内分泌系统的有害作用等(非特异性的)。因而,控制噪声、消除或减轻其危害,已成为劳动卫生和环境保护工作的当务之急。我区厂矿企业中噪声污染相当普遍,据1983年对银川市部份工厂的重点调查结果:在47家工厂中有噪声作业点348个,其中噪声声级超过90dB(A)者有158个,占45.4%;各行业中,以纺织业的噪声问题较突出,在
With the development of industry and transportation, the noise pollution is increasing day by day. A lot of research data show that the impact of noise on the human body is multifaceted, such as hearing impairment (specific), detrimental effects on the nerve, cardiovascular, endocrine system (non-specific). Therefore, controlling noise and eliminating or lessening its harm has become a top priority for labor health and environmental protection. According to the key survey results of some factories in Yinchuan City in 1983, there were 348 noise operation points in 47 factories, among which there are 158 noise level exceeding 90dB (A) Accounting for 45.4%; in various industries, the noise problem in the textile industry is more prominent
