Дифференциальная диагностика нейросенсорной тугоухости профессионального и непрофессионального генеза

40 patients with the occupational neurosensoric dullness of hearing and 30 patients with the neurosensoric dullness of hearing of the non-occupational genesis have been examined using the electrophysiological procedures. The study findings have been processed using the discriminant analysis as a result of which the mathematical formulae for the differentiation of two states (neurosensoric dullness of hearing in the consequence of the production noise and the neurosensoric dullness of hearing of non-occupational genesis) have been formed.
