5considered. The solution of the problems under consideration is due to the urgent problems of environmental
monitoring in connection with noise pollution by various types of transport, industrial and natural sources. As
a result, geoecological risks are generated that affect the social environment, first of all, on humans, as well as
on buildings. Multivariate numerical models of interwave interactions and their mechanisms are presented
and analyzed. As a result of interactions, various physical effects are generated that determine the degree of
influence of conjugate wave fields on the medium. On the basis of numerical modeling and the results of field
experiments, estimates of increased geoecological risks are given.

The first of a large number of works on the generation of the magnetic field of the Sun (MPS) and planets
is considered to be the work (Lehrmor 1920), which discusses the need to introduce a self-excitation mecha-
nism to amplify a weak electron current and obtain a strong MPC. In many subsequent works, models of self-
excitation of an electronic current are investigated. In the previous [1] and this paper, the current generating
the MPC is the motion of a positively charged liquid or gas. It is known that the current density is proportional
to the charge density and the velocity of their movement. According to the known estimates of the parame-
ters of the structure of the Sun the calculated charge densities and currents create magnetic fields (MP) for
seven of the top layers of the Sun: chronosphere, chromosphere, photosphere and four layers of the convec-
tive zone. The maximum permissible estimates of currents and MPS are obtained. From these estimates of the
kinematics-gravitational ion dynamo model, it follows that all layers of the model, taking into account certain
restrictions, can participate in the generation of MPS.

One of the tasks of geoecological monitoring of the environment is related to the assessment of levels of
technogenic noise representing a danger to people.
In this situation, there is a necessity of signals extraction from external noise and their parameters meas-
urement. Other problem is related to the considered problem - noise source direction determination. In this
work characteristics of seismic and acoustic wave fields, created by technogenic sources, are investigated.
Railway, heavy tracked and wheeled transport as well as CV-40 seismic vibrator [1] are considered as sources.
In this work, the approach based on combining the algorithms of quadrature accumulation [2], polariza-
tion analysis [3], controlled directional reception [4] and directional coefficient determination [5] is considered
for signals extraction and noise source direction determination.
The study of the characteristics of the noise sources under consideration is of interest for the problem of
geoecological monitoring of the social and natural environment and in other problems.

The paper presents the application of mathematical modeling of wave fields in the problem of studying
the sensitivity of the method of active vibroseismic monitoring to small changes in velocity parameters in the
inner areas of the Earth's crust. The change in the parameters of the wave field recorded on the surface is de-
termined depending on the size of the areas of changes, its location relative to the source and receivers, and
the wavelength of the probing signal. Analytical estimates are obtained for variations in vibroseismic vibrations
recorded on the surface for spherical inhomogeneity in a homogeneous model of the Earth's crust in contact
with the upper mantle, as well as variations in the total wave field for a realistic model of the Earth's crust and
inhomogeneous inclusion based on the application of the finite difference method to solve the problem of dy-
namic theory of elasticity. The results of mathematical modeling are compared with experimental data of ac-
tive vibroseismic monitoring of the Baikal rift zone.
