However, under certain working conditions, the noise in the cab of construction machinery is still relatively serious. Surveys show that exposure to strong noise can lead to tinnitus and hearing loss. As long as the time is not long, once you leave the noise environment, it will soon return to normal. However, if you are exposed to strong noise for too long, your hearing will decline significantly. It can even cause noise-induced hearing loss and seriously damage the physical and mental health of construction machinery drivers.
