Analysis of noise monitoring results of key industry enterprises in a certain district of Shenzhen from 2022 to 2024

Abstract

Abstract:

Objective To understand the current situation of occupational noise hazards in key industry enterprises in a certain district of Shenzhen，laying a scientific foundation for formulating targeted preventive and control countermeasures. Methods From 2022 to 2024，370 key industry enterprises with noise hazards were selected as the research objects. By collecting basic enterprise information，implementing hygienic surveys，noise operation post detections and evaluations on the production site in accordance with various industry standards，and comprehensively evaluating the use of personal protective equipment according to relevant guidelines. Results From 2022 to 2024，the rate of enterprises with excessive noise was 45.68%，and the rate of excessive noise points was 29.82%. The differences in the rate of excessive noise points among enterprises in different years were statistically significant（χ²=20.101，P<0.01）. Large/medium-sized enterprises had the most serious excessive noise situation，and the differences in the rate of enterprises with excessive noise and the rate of excessive noise points among enterprises of different scales were both statistically significant（χ²=20.911，41.190，both P<0.01）. The furniture manufacturing industry and the metal manufacturing industry had the highest levels of excessive noise，and the differences in the rate of enterprises with excessive noise and the rate of excessive noise points among enterprises of different industry categories were both statistically significant（χ²=45.253，407.060，both P<0.01）. Enterprises from Hong Kong，Macao，and Taiwan had the highest rate of excessive noise and the lowest rate of excessive noise points，and the differences in the rate of excessive noise points among enterprises of different economic types were statistically significant（χ²=11.422，P<0.01）. In addition，16.78% of the monitoring points did not have protective facilities installed，and 22.68% of the workers at noise-exposed positions did not receive or wear ear protectors. Conclusion The noise hazards in key industry enterprises in a certain district of Shenzhen cannot be ignored. There are differences in noise over-standard situations and the implementation of protective measures among enterprises of different scales，industry categories and economic types. It is necessary to formulate targeted noise prevention and control strategies and strengthen occupational health management.
