There are direct and invert correlations between the indices of the electroencephalography and. electroneuromyography in the groups of patient with vibration-induced, diseases and. occupational neurosensoric dullness of hearing. Despite the fact that coincidence of correlation indices was observed in one case only, this fact may testify to the similar influence of physical factors (local vibration and. noise) on the employees' organisms and. it may confirm that the changes may be observed both in central and peripheral nervous system, that is, the whole neurosensoric complex is activated.
