Results of the research are evidence of changing muscles reflex activity of human lower extremity under the influence of sound stimulus of various frequency range together with the vestibular burden. The most change of the H-reflex was observed under the sound stimulus of 800 hertz. Not only the proprioceptive but auditory sensory system takes part in the regulation of the brain reflex activity. Existence of different labyrinths actions, according to the situation, on the interneuronic inhibitory ways of the postsynaptic inhibition of the salens muscle’s motoneurons is supposed.
