EXPERIENCE OF ESTIMATION AND REDUCTION OF NOISE AND VIBRATION OF INDUSTRIAL ENTERPRISES OF RUSSIA

Industrial noise and vibration leads to the workers disease, fatigue breakdown of pipeline and apparatus junction, decreasing of machine operating characteristics etc. According to statistics, amblyacousia and vibration illness takes the first places among all the other professional diseases. Investigations of noise and vibration levels at the operator's positions of "Volgoelectromontazh-1" Joint Stock Company of Russian Federation were done. Measurements were carried out according to existing methods and standards. In total 27 operator's positions were investigated in the main building and in the shop of consumer goods. The results of measurements showed, that for some positions (pendulum saw, cutting-off lathe, presses etc.) there were significant excesses of the sanitary standards of noise levels. Complex of measures of noise reduction was developed, including technical decisions and organizing measures. Results of measures implementation shows good efficiency of noise and vibration reduction.
