[A comparative analysis of the neurophysiological mechanisms of hearing disorders of different origins by the indices of the background and evoked bioelectrical activity of the brain].

The hearing function was studied as was the bioelectrical activity of the brain in workers exposed to noise in their occupations and in those persons coming into contact with ionizing radiation with normal and disordered hearing. The studies made showed that those persons under exposure to ionizing radiation exhibited more pronounced disturbances in the brain stem structures of the acoustic analyzer than those exposed to noise even if they were early in the course of the ear disorder. We consider it expedient to undertake studies on bioelectrical activity of the brain to gain further insights into the mechanisms of sensorineural hearing loss.
