The article is devoted to the topical direction - study of electromagnetic fields and infrasound built-up areas. These negative factors are not perceived by basic human receptors, and often people underestimate the danger posed by the sources of electromagnetic fields and infrasound. Currently, environmental monitoring system of infrasound and low-frequency electromagnetic fields in built up areas includes a study of the amplitude spectrum. The negative impact of these factors is evaluated separately without taking into account their mutual influence on the biological object. However, in the literature there is the data showing the effect of noise on the electrical characteristics of the human body. In this regard, the authors consider appropriate definition of the integral energy of low-frequency effects on built-up areas that will objectively evaluate the overall level of various kinds of fields at the point in space at a given time and their negative impact on biological objects. The authors propose a new approach to ecological monitoring of infrasound and low-frequency electromagnetic fields on the basis of determining the energy parameters. The paper theoretically proved it possible to determine the total energy impact of infrasound and low-frequency electromagnetic fields, taking into account the mutual influence of these factors on biological object. The article presents an algorithm of the synergistic index of the low-frequency energy of negative impact on the basis of measurements of integrated intensities of infrasound and low-frequency electromagnetic fields. Definition of the synergistic energy of low-frequency effects allows objectively assessing the negative effects of electromagnetic fields and infrasound on biological objects, as well as fundamentally new challenges to improve environmental safety of built-up areas and the protection of the population from the effects of these factors.
