ABSTRACT
The audiometric curve profile (appearance) has been an important characteristic diagnostic criterion of noise-induced hearing loss during the expert evaluation of the relation of the hearing organ disease with the profession of workers exposed to noise. The rise of auditory threshold in the area of sensation of the frequencies 3 and/or 4 kHz, characteristic for noise exposure, are construed by professional pathologists as an audiometric “peak” or “valley”, however, there are their standard definitions. The objective of this work was to determine the dependence of the audiometric curve profile of civil aviation flight crew members (n = 1294) on production and non-production factors. Based on the tonal threshold audiometry, the authors conducted expert and mathematical assessment of the audiometric curve appearance, the significance of its assessment in the diagnosis of noise-induced hearing loss. The results obtained indicate a relatively low diagnostic significance of the “visual analysis of the audiometric curve”, which is recommended to consider at most as for the generation of initial hypotheses. The presence of an audiometric curve profile characteristic for noise exposure is not the basis for the final diagnosis of occupational disease of the hearing organ without obtaining the reliable information about working conditions, confirming the long-term systematic exposure to noise, the levels of which exceed the permissible values (maximum permissible level of 80 dBA).
