ACOUSTICAL ABNORMALITIES IN RECEPTOR, BRAINSTEM AND CORTICAL SITES OF AUDITORY ANALYZER AT NOISE INFLUENCE WITH INTENSITY AND CHARACTER PROPERTIES

Yavorovskiy O. P., Vertelenko M. V., Shidlovskaya T. V. (Kiev)

Summary

There was estimated of noise influence characteristics on the different sites of auditory analyzer - receptor, brainstem and cortical. 52 worker of "noisy" professions were examined and 20 persons in healthy somatic and otologic state in the capacity of control group. These workers were divided on two group, according influence noise intensity. Punchers were in the first group (equivalent level of impact noise - 98,51,3 dBA). Carpenter of woodworking machine were in the second group (equivalent level of intermittent noise - 90,00,5 dBA). There was detected character of changes on the different sites of auditory analyzer subject to industrial noise intensity. More informative subjective and objective criteria was adjust for precocious diagnostic of acoustical abnormalities at noise influence.
