TEMPORARY INDEXES OF SHORT LATENCY AUDITORY EVOKED POTENTIALS IN WORKERS OF "NOISY" PROFESSIONS WITH INITIAL SENSORINEURAL MANIFESTATIONS

Shidlovskaya T.A., Shevcova T. V. (Kiev)

Summary

It was held the examination of the function of central departments of acoustic analyzer of low-staged workers of "noisy" professions with initial sensorineural manifestations by the data of registration of short latency auditory evoked potentials (SLAEP). The tested patients were differed into two groups. Detection of SLAEPs in 1 and 2 groups of the workers of "noisy" professions led to detect that in first group, in which the hearing on the tones in conventional thresholds diapason (0,125-8 kHz) was inside the limits of standard and in extended (9-16 kHz) was disturbed, there were no trustworthy difference in latency period of waves I-V of SLAEPs in compare to standard (C-group). Obtained data prove that at influence of the noise even in the early terms and at the different level of manifestation the brain stem structures of acoustic analyzer are suffered, too. That's why the timely therapy on the early stages of acoustic disturbances allows preventing the development of professional tight-hearing of the workers of "noisy" professions.
