The reporter learned from Foshan occupational disease prevention and control institute that in recent years, hearing-related occupational noise deafness occurred frequently in Foshan. 1n 2012 and 2013, there were 23 and 24 confirmed cases of noise deafness in Foshan, and 5 cases were confirmed in the first two months of this year. The incidence of noise deafness has caught up with the trend of pneumoconiosis

18 people in an enterprise in Shunde were diagnosed with noise deafness

Master Li is a worker in a container car factory in Shunde, where he has worked for seven years. According to its introduction, since the beginning of 2012, 1 feel hearing loss, and deafness, tinnitus, neurasthenia symptoms. Her wife, Ms. He, told reporters yesterday that at the beginning of the disease, she felt it was difficult to communicate with her husband. Master Li always complained that his family’s voice was too small. Already 50 years old, he thinks it may be because of his age that his hearing has declined. At the end of 2012, the factory stopped production and moved to other places, and the workers asked for physical examination before leaving. The results surprised the staff of Shunde Vocational Prevention 1nstitute: more than 100 people had abnormal hearing, and dozens of people were suspected of pneumoconiosis; 1n 2013, 18 workers were finally diagnosed as occupational deafness, and nearly 10 workers were diagnosed as pneumoconiosis

according to the staff of Foshan vocational Prevention 1nstitute, most of the workers in the factory produce in closed containers, which produces a lot of noise and dust, causing great damage to the hearing of workers, and the factory has not carried out physical examination for many years. This is also the largest number of enterprises in Foshan< According to Chen Song, director of Foshan vocational Prevention 1nstitute, hearing test has not been included in the routine examination of occupational diseases due to the limitation of testing equipment" 1n recent years, we have found that the production environment of many enterprises may lead to noise deafness. " Foshan began to summarize the incidence of occupational noise deafness in 2009: before 2012, the number of confirmed cases was single digit, and then blowout" 23 cases were diagnosed in 2012, 24 cases in 2013, and 5 cases in the first two months of this year. " And this is only the number of cases that have reached the diagnostic standard according to the statistics of the Municipal 1nstitute of occupational health prevention. 1n the occupational health examination of workers exposed to noise, more and more people are found to have abnormal hearing or hearing impairment by doctors. Because the occupational health examination institutions do not need to report hearing abnormalities, there is no data of hearing abnormalities in Foshan occupational noise deafness a progressive sensorineural hearing impairment caused by workers’ long-term exposure to productive noise at work. The national noise standard for the production environment is 85 dB. 1n fact, people are not adapted to the noise of 80 dB. Working in a noisy environment for a long time will affect the ear frequency and lead to hearing loss. For example, in the canteen, textile, machinery and equipment workshop and other places are more common< Protection protection over 108db earplug + helmet 1. All personnel working in hazardous noise areas must wear hearing protectors. Earplugs are commonly used, and the sound insulation effect can reach 30-40db. When the steady-state noise is above 108db (a), ear plugs and earmuffs or helmets should be worn at the same time. When the steady-state noise is above 118db (a), daily contact time should be limited
