Abstract: Objective To investigate the distribution status of workplaces noise hazards in Huizhou in 2020,and provide a scientific basis for the prevention and control of occupational noise hazards. Methods Data of noise hazards from 5 407 enterprises in 7 counties and districts in Huizhou in 2020 were collected by cluster sampling method and analyzed by descriptive epidemiology. Results Among the 5 407 investigated enterprises,761 enterprises exceeded the workplace noise standard and exceeding standard rate was 14.07%. The exceeding standard rate of post noise was 16.88%（2 694/15 963）,and the exceeding standard rate of place noise was 18.84%（1 944/10 316）. A total of 117 351 people were exposed to noise hazards,and the exposure rate was 23.58%（117 351/497 691）. The declaration rate of occupational disease hazards was 17.66（955/5 407）,the physical examination rate of noise item was 69.16%（81 159/117 351） and the abnormal rate of examination results in noise item was 1.01%（817/81 159）. The occupational health training rate of the principal person was 55.41%（2 996/5 407）,the occupational health training rate of manager was 28.50%（1 541/5 407）,and the occupational health training rate of people exposed to hazard was 64.40%(112 605/186 443). The noise hazard in different distribution categories was comprehensively evaluated according to the weighted scoring results of the 4 dimensions of situation of workplace noise exceeding,noise exposure and declaration,physical examination of noise hazard exposed people and occupational health training. Huiyang District was the most serious（59 points） in the distribution of counties and districts,limited liability company was the most serious（74 points） in the distribution of economic types,micro enterprise enterprise was the most serious（34 points） in the distribution of enterprise size,and electricity,heat,gas and water industry was the most serious（26 points） in the distribution of industry types. Conclusion The current situation of noise hazards is different in varying degree on various types of Huizhou enterprises,suggesting that Huiyang District,limited liability companies,micro-enterprises,electric,heat,gas and water production and supply industries should be payed attention to in the future noise prevention work.
