Objects of research – 1568 persons of working age (917 men, 651 women). The study was conducted on the principle of a simple random sample with a survey on specially designed questionnaires with the inclusion of a short version of the who questionnaire on quality of life. Account of gender, age, profession, mode of work, working conditions, experience, fatigue at work, place of residence, living conditions, self-reported health, self-reported hearing noise and reaction to noise on the production and out of production, attitude towards a healthy lifestyle, Smoking, alcohol, life satisfaction, the impact of hearing loss on quality of life. The importance of psychosocial factors was judged by the proportion of respondents who chose the appropriate answer: with a specific weight of less than 25%, the factor was considered to be of little importance for the analyzed cohort, from 26 to 50% – moderately significant, from 51 to 75% – highly significant and more than 75% – very high. To quantify the indicators using a four-point scale (answers like: Yes, rather Yes than no, rather no than Yes, no) used an integral indicator calculated by the formula:In = [(a – d) + (b – c)/2]/n,where «a» – is the number of respondents who gave a positive assessment of the sign; «b» is the number of respondents who gave a rating of «more positive than negative»; «c» – the number of respondents who gave a rating of «rather negative than positive»; «d» – the number of respondents who gave a negative evaluation; «n» – is the total number of respondents to the question.Working conditions of employees were additionally assessed by objective indicators (sanitary and hygienic characteristics of working conditions). Correlation analysis was used for comparative analysis. The significance of the differences was calculated using student's t-test for continuous and Fisher's criteria and χ-squared for categorical variables. All factors with a significance level less than 0.05 were considered significant. By occupation, 37.0% of the respondents were workers, 9.6% – members of civil aviation flight crews, 26.5% – education and health workers, 11.2% – workers engaged in trade and provision of services to the population, 12.7% – able-bodied population temporarily unemployed at the time of the survey. In the group of workers, an independent subgroup of the hearing impaired (100 people, 6.4%) was allocated, who worked on the mechanical equipment of an industrial enterprise. The median age was 39.9±6.3 years. It was found that hearing loss in working age has an extremely high medical and social significance and is equated with normal hearing people to the loss of at least 60% of "all health", and workers with reduced hearing – not less than 70%. A model of prevention of sensorineural hearing loss, which is based on the principles of social partnership of all participants in the system of labor relations.
