Hearing measurement of 6,784 workers exposed to industrial noise helped to determine the prevalence of occupation-related hypoacusis, which was estimated to vary from 4.5 to 53%. The work record of 10 to 14 years was found to be most risky for the development of cochlear neuritis. During the first 10 years of exposure to industrial noise occupation-related hypoacusis developed in 2% workers, which is within the 5% limits of noise susceptible subjects. Considering hearing integrity during 10-year exposure to industrial noise, it can be assumed that maximaly allowable levels equal to 85 dB are acceptable. Numerous observations of the hearing condition allow the conclusion that the zero degree of hearing impairment, i.e. "signs of noise effects on the hearing organ", should be viewed as an initial form of occupational disease (prenosological form), which requires close follow-up of such workers.
对6784名接触工业噪声的工人进行听力检测，有助于确定职业性听力减退的患病率，估计患病率在4.5%至53%之间。发现工作10至14年的记录对耳蜗神经炎的发展风险最大。在接触工业噪声的头10年中，2%的工人出现了职业性听力减退，这在噪声易感人群5%的范围内。考虑到在10年接触工业噪声期间的听力完整性，可以假设85分贝的最大允许水平是可以接受的。对听力状况的大量观察得出结论，听力损伤的零级，即“噪声对听觉器官影响的迹象”，应被视为职业病的初始形式（前驱形式），需要对这些工人进行密切随访。
