[Differential description of heart rate regulatory mechanisms of young men at sensory-motor and psychoemotional load during high frequency sound exposure].

The goal of the study was the differential description of the heart rate regulatory mechanisms of young men and productivity of task performance during sensory-motor and psychoemotional load on the background of high frequency (4000-8000 Hz) sound exposure. Analysis of statistical and spectral components of the heart rate variability was done for description of heart rate regulatory mechanisms. Sensory-motor and psychoemotional load was studied with Landolt rings.
