Do employees need to undergo occupational health examination when wearing noise earplugs?

Noise up to 80dB constitutes an occupational hazard. From the point of view of occupational health, there are sounds harmful to hearing and health or other hazards, and the operation with equivalent sound level of 8 hours a day or 40 hours a week is called noise operation. In the process of occupational disease identification, only workers engaged in noise operations can be diagnosed as occupational noise deafness. According to the regulations of physical factors, the limit of steady noise is 85dB(A), and the equivalent sound level of unsteady noise is 85dB (a). The working day per week is not 5d, so the equivalent sound level of 40h needs to be calculated, and the limit value is 85dB(A). Basically, when the 8-hour equivalent continuous A sound level in the working environment of an enterprise is greater than 80dB, employees need to undergo noise-related occupational health examination, and when it is greater than 85, they need to be equipped with personal protective equipment such as earplugs.
