Experience of Estimation and Reduction of Noise and Vibration of Industrial Enterprises of Russia

Abstract

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.

To Thev Question of Reduction of Negative Impact of Infrasound Radiation in Conditions of Urban Territories on the Example of Samara Region

“…Например, это повышение тихоходности машин и оборудования, перевод инфразвукового излучения в диапазон средне-и высоких частот звука. Эффективным является использование устройств активной компенсации звука, принцип действия которых заключается в формировании звукового сигнала той же амплитуды и частоты, что и нежелательный звук, но противоположного по фазе [1,2,7,8,11].…”

Research of Infrasound Radiation in Living Territory of City District Samara

“…Инфра-частоты около 12 Гц с мощностью 85-110 дБ вызывают приступы движения и головокружение, а колебания с частотой 6 Гц и от 15 до 18 Гц вызывают чувство тревоги и в конечном итоге страха и паники [3,[9][10][11][12].…”

Results of study of environmental noise before, during and after COVID-19 period in conditions of Samara region of Russia and approaches to noise reduction

“…Presently acoustical pollution is serious problem for population [3][4][5][6][7][8][10][11][12][13][14]. Transport and industry are the main noise sources of urban territories.…”
