最近苏联卫生部批准的“作业场所噪声容许水平的卫生标准”(NO 3223-85),自1985年3月12日起执行。该文件体现了按作业种类规定噪声标准的原则。卫生标准中包括执行监督的必需资料和确定作业场所噪声分类、特征、容许水平、标准测量的总要求及主要预防措施。鉴于现代生产设施功率增加和设备大型化的发展趋势,对低频噪声的卫生学意义日益引起重视,因此标准的频程扩大包括31.5赫中心频率。噪声容许水平按作业活动类别及有关作业点和作
The latest “Sanitary Standard for Permissible Levels of Noise at Workplaces” (NO 3223-85) approved by the Soviet Ministry of Health has been implemented since March 12, 1985. This document reflects the principle of noise standards by job type. Health standards include the necessary information for the implementation of supervision and determine the classification of noise at the workplace, characteristics, allowable levels, the general requirements of the standard measurement and the main preventive measures. In view of the increasing power of modern production facilities and the trend toward larger equipment, there is increasing emphasis on hygienic significance of low-frequency noise, so the standard frequency range expansion includes a 31.5 Hz center frequency. Allowable noise level according to the type of activity and related work sites and operations
