“…In accordance with modern concepts, noise and infrasound are classified as harmful and dangerous physical factors, the impact of which causes a decrease in efficiency and reliability of activity, and a long or short cumulative effect causes the development of a number of diseases [1][2][3].…”

The chapter outlines the methodological aspects of monitoring industrial and transport noise, including the main physical characteristics, features of sources, measuring instruments, features of hygienic regulation of industrial and transport noise, means and methods of protection against it. It is shown that industrial facilities and most modes of transport are sources of high-intensity noise, the spectrum of which is dominated by frequencies of the low-frequency infrasonic range. The close physical nature of these ranges contributes to the propagation of such noise with low attenuation, and they have good penetrating power, so most noise protection devices are ineffective. This requires careful medical supervision of persons working in such conditions, improvement of means and methods of protection against industrial and transport noise.

The review presents an analysis of literature sources devoted to the study of changes in the nervous system in patients with vibration disease. Vibration-mediated cellular hypoxia, which occurs as a result of spastic changes in blood vessels, phase fluctuations in intravascular pressure, impaired blood and lymph outflow, causes suppression of energy metabolism, contributes to disorders at the level of receptor (glutamate, GABA-ergic, dopamine and cholinergic) and synaptic structures, conductors of pain and temperature sensitivity (demyelinization), analyzing neurons in the parietal region of the brain, regulatory proteins of the nervous tissue (NF-200, GFAP S-100). A low-amplitude, irregular, disorganized and sometimes deformed EEG spectrum with a predominance of the alpha wave and a shift of the alpha rhythm to the left reflects changes in the spontaneous electrical activity of brain structures in patients. With an increase in the experience dose of vibration-noise exposure, the dominant alpha activity changes to slow-wave or polyrhythmic. Mild and moderate diffuse changes in the brain become focal in nature, cortical-subcortical relationships are disrupted at the diencephalic level, creating a pathophysiological basis for sensorineural (sensory-neural) hearing loss, especially in patients with a genetic predisposition mediated by genes encoding proteins of the heat shock system. The psycho-emotional status of patients is characterized by a hypochondriacal focus on the state of health, mental disadaptation, psycho-emotional disorders in the form of anxiety, depressive mood. The analysis of literature sources on the mechanisms of the formation of neurological disorders in patients with vibration disease revealed the lack of data on the state of the multicomponent ghrelin system interacting with GHSR-1A and GHSR-1B receptors, which determines a new vector in further experimental and clinical studies.

Relevance. In the new edition of the Labor Code (as amended on 02.25.2022), risk-oriented approaches to management in the field of labor protection are fixed, which necessitated the revision of regulatory and methodological documents, including in the field of occupational medicine based on the methodology for assessing occupational risk to workers' health. The study aims to substantiate and develop a numerical scale for assessing the group attributive risk of hearing loss from exposure to industrial noise. Materials and methods. The authors have carried out an expert-analytical study of materials on qualitative and quantitative a priori and a posteriori assessment of occupational risk. Results. The scientists have confirmed the advantage of attributive risk over other indicators for assessing the risk of hearing loss from noise. The numerical scale of the assessment of the attributive risk of hearing loss in relation to the risk-oriented hygienic classification of working conditions and the assessment of the relationship of hearing impairment from noise with work, depending on the magnitude of the attributive risk and etiological proportion, is substantiated. We have justified the categorization of the attributive risk of hearing. Limitations. Features of the model for assessing hearing loss due to noise exposure according to GOST R ISO 1999:2017. Conclusion. The development of a quantitative scale for assessing the attributive risk of hearing loss not only harmonizes the hygienic assessment of the noise risk factor with international practice, but also contributes to the development of the methodology for assessing and managing occupational risk. Keywords: risk assessment; quantitative assessment scale of the attributive risk of hearing loss from noise; categorization of occupational attributive risk; risk-oriented hygienic criteria and classification of working conditions; the rule of "equal energy"; connection of health disorders with work Ethics. In preparing the article, the authors were guided by the Ethical principles of medical research set out in the Helsinki Declaration of the World Medical Association of the last revision.
