ABSTRACT
Risk factors of noise-induced hearing loss include aging, high blood pressure, smoking, noise, etc. Presbyacusis and the regular long-term noise impact on the auditory analyzer are characterized by unequal contributions to hearing loss throughout a person’s life. The objective of this work is to analyze the interaction between the changes of actual thresholds of audibility of noise profession workers, related to age and the main workplace factors. The authors conducted the analysis of working conditions and the study of tonal hearing thresholds in 1350 civil aviation flight crew members. It is shown that the hearing of workers is affected by a number of factors, but the nature and the severity of exposure by these factors vary for frequencies 1 and 4 kHz, with the age being the most significant factor in all cases. The highest value of “hearing quality” is characteristic for pilots of Boeing (the noise of 74.1 dBA), in the pilots of all other aircraft the hearing quality is significantly lower. It determines the advisability of a deeper factor analysis with simultaneous consideration of all the selected factors, as well as in the entire range of conventional frequencies, taking into account the age physiological hearing norm.
