[The evaluation of indices of noise impact on humans]

Due to noise, information processing changes, rate and quality of work deteriorate. Laboratory experiments prove noise exposure to increase dyastolic blood pressure. Multiple factors of occupational environment induce significant individual variability of blood pressure, putting a little value to blood pressure changes. Functional changes of visual analyzer are expressed by reliable increase in eye electrical sensitivity threshold and by lower acuity of vision. Changes in oculomotory coordination are expressed by longer performance time and higher error rate. The authors discuss possible use of psychophysiologic methods to evaluate influence of noise on humans.
