[Physiological mechanisms of prevention of occupational hypoacusis].
This study and mathematical analysis by constructing a correlation matrix, a diagram of significant correlations, a multiple regression model of 77 indices of the body's main systems in 91 drift miners and drillers who had a service length of 7-27 years showed the physiological mechanisms of auditory function system and revealed 3 basic levels of energy metabolism regulation: 1) neuroreflectory (cortical mechanisms) and autonomic (sympathetic) adaptive-and-homeostatic regulation; 2) neurohumoral and metabolic adaptive-compensatory ergotropic self-regulation of blood circulation and respiration; 3) parasympathetic neuroreflectory and metabolic compensatory trophotropic regulation of respiration and blood circulation. The established regularities were used as a basis in developing methods and criteria for individual sensitivity to noise, criteria for specific adaptation during labour activity.
