Hygienic evaluation of working conditions of workers, engaged in main works of aeronautical engineering industry, examina-tion of the state of the auditory analyzer, using a pure tone audiometry, registration of short-latent and long-latent auditory evoked potentials and acoustic impedance-metry in 53 workers of «noisy» professions with initial sensoneural deafness and 20 persons, healthy from somatic and otology point of view in the control group, have been conducted.. It is determined that high levels of noise have been recorded at work places of workers of a number of occupations. According to the data of the subjective audiometry the examined workers were divided into 2 groups: 1st — with symmetric hearing impairments accord¬ing to the sound perception type, in which hearing of tones in the part of the conventional band is within the normal value, but impaired in the extended band (28 persons); 2nd — also with hearing impairments in the conventional band (24 persons). The obtained data point to the advisability of studying central parts of the auditory analyzer in workers of «noisy» professions with initial hearing impairments by the sound perception type, as this allow to reveal hearing impairments in early pre-clini¬cal periods and begin treatment and preventive measures in due time, thus preventing development of sensoneural deafness.

Key words: aeronautical engineering industry, noise, auditory analyzer, sensoneural deafness
