[Peculiarities of the development of occupational deafness in the workers of "noisy" professions employed in experimental mechanical engineering].

The objective of this work was to evaluate the health status and hearing function in the workers employed in experimental mechanical engineering and exposed to the combined effect of noise and occupational psychoemotional stress. The authors describe specific clinico-audiological characteristics of hearing disturbances diagnosed with the help up-to-date highly informative and objective methods for the evaluation of the function of acoustic analyzer, such as impedancometry, threshold tonal high-frequency audiometry, registration of distortion product otoacoustic emission. Criteria for the early diagnosis of neurosensory loss of hearing of <<noise etiology" are proposed. The cause-and-effect relationship between central hemodynamics patterns, intensity of work, and noise level has been established.
