我国卫生部和国家劳动总局颁发的《工业企业噪声卫生标准》(试行草案)中,根据等能量观点(即暴露时间减半噪声的允许标准增加3分贝),对每个工作日接触噪声时间他长短,规定了如表1所列的噪声标准。在有些纺织、机械加工等企业的生产过程中,职工直接受机器持续噪声影响,可按表1规?

China’s Ministry of Health and the State Administration of Labor issued the “Noise Standards for Industrial Enterprises” (draft), according to the energy point of view (that is, the exposure time by half the standard noise increase of 3 dB), on each working day exposure to noise time he Length, provides for the noise standards listed in Table 1. In some textile, machining and other enterprises in the production process, workers directly affected by the machine noise continued, according to Table 1 regulation?
