“…Occupational hearing impairment can develop even in conditions when noise levels do not exceed permissible ones. Usually, it happens when a combination of high work intensity with the necessity to select speech/non-language signals takes place, which was confirmed by the results of our study [42]. Obviously, researches in this field should be continued.…”

The objective of the research was to compare Ukrainian statistics in occupational morbidity with data of other countries, to analyze the trend of the occupational hearing loss formation in Ukraine over a six-year period (2011 -2016), to consider a modern state of sensorineural hearing loss detection and prophylaxis. Materials and methods. A comparative analysis of occupational morbidity in Ukraine and other counties within 2011-2016 years was based on the data obtained from the reports of the Social Insurance Fund of Ukraine, Statistical Collector, Eurostat, the International Labour Office, the Bureau of Labor Statistic, etc. Results. The difference in Ukrainian and international statistics in occupational morbidity can be explained by the diversity in the surveillance systems. The sharp decline in occupational morbidity in Ukraine within 2014-2016 is connected neither with the improvement of prophylactic measures nor with creating better work conditions. Sensorineural hearing loss has been ranked fourth in occupational morbidity accounting for 2.5%-4% of professional pathology and is underestimated. Conclusions. The underestimation of occupational hearing loss in Ukraine is determined by economic and organizational reasons, scarce diagnostics during medical examinations, peculiarities of the national surveillance system. A possible solution to this problem includes but is not limited to the reduction in countless pathologies caused by a high level of unreported employment, the establishment of unified sensorineural hearing loss classification, the increase in an accuracy of noise zone determination (noise-map construction), the performance of pure-tone audiometry in extended range (9 -16 kHz).

“…The conventional approach of rating sound exposure by the principle of energy equivalence can lead to a misleading assessment of their physiological costs [ 7 ]. First of all, it concerns professions connected with the selection of speech in the noise background – call centres – [ 8 ] or nonverbal acoustic messages – sonar operators of submarines [ 9 , 10 ] or geophone operators in coal mines [ 11 ]. The perception, selection and distinction of speech and nonverbal acoustic signals, transmitted by abstract sound symbols, are significantly different and much more complex in the second case.…”

Summary Background The biological effects of noise depend on its physical parameters, combination with other hazards, the content of acoustic signals. This article aimed to analyze the difference in biological effects caused by the selection of nonverbal and verbal signals in conditions of a high level of work intensity. Methods Work conditions, physical characteristics of noise, levels of work intensity were studied among 75 telephone operators and 96 geophone operators. Levels of permanent hearing thresholds, evaluated by pure-tone audiometry, and results of self-estimation of operators’ health were compared. The contribution of the content of acoustic signals in the shifting of hearing thresholds was evaluated by the one-way analysis of variance. Results Selection of acoustic signals in the noise background (< 65 dB), in conditions of high work intensity, causes a significant increase of permanent hearing thresholds in both studied groups comparing to the non-noise exposed population. A combination of the high level of work intensity and distinguishing of nonverbal acoustic messages leads to significant deterioration of health resulting in decreasing of hearing sensitivity and a number of complaints on the state of health (p < 0.05). The content of acoustic signals significantly contributes to the biological effects of the nose. Conclusion Obtained results testify necessity to revise safe criteria of noise levels for workers, engaged in selection, recognition and distinguishing of acoustic messages in the noise background combined with a high level of work intensity. In case when the energy of the acoustic field cannot be reduced, occupational safety measures should focus on decreasing of work intensity.
