[Changes in occupational cochlear neuritis and its incidence in Moscow]

The authors analyze completeness and reliability of State statistics exemplified by occupational deafness. Cochlear neuritis morbidity appears to change unfavorably. For calculation of the necessary parameters, the authors suggest a rational method considering only number of those working in noisy conditions, but not the total number. The results appear more objective, that is essential for adequate evaluation of occupational deafness risk for main industries and occupations exposed to noise, in order to manage this risks effectively.
