. Introduction and review.

In world practice there are numerous data about an ecological balance disruption in biotope under operating of mines, hydraulic structures and large geophysical events, such as, hurricanes, tsunami, tornado etc. All this events are sources of an infrasound [1-4,7].

The impact of an infrasound on environment is persiform and is exhibited in the following:

§ Infrasound noise in settlements, separate buildings and facilities, generation of undesirable (harmful to an organism) oscillations directly in habitation and workrooms [1,6,7];

§ local changes of lithosphere activity mode and in the structure of gas and aerosol in bottom layer of air as a result;

§ structural rearrangements in soil, changes in water balance of surface waters and in condition of flora near large industrial plants; § stimulation of launching (trigger) processes in the lithosphere reducing in turn to spontaneous development of large-scale geophysical events (directed seismically), such as departure of avalanches, a drop-stone etc.[17,23];

§ complex character of impact of the listed factors on lithosphere, hydrosphere and atmosphere, which causes generation of structure complicated wave disturbances, as a response of local resonance structures[14,15,25].

The reinforced attention to this geoecological problem appeared in last years as a result of understanding a role and significance of influencing structural infra-low-frequency of oscillations on ecological equilibrium in environment [10,18]. The most imminent and acute problem of today is the realization of special researches aimed on development of ecologically justified norms and extreme admissible doses of infrasonic effect.

The basis of such researches is the development of methods and hardware for diagnostic of natural and man-caused infrasonic fields.

Basing on the results of conducted experiments and obtained practical outcomes the comprehensive investigations of a problem of interplay of generated in rocksphere, hydrosphere and atmosphere low frequency wave processes with a biotope will be made.

Expected results.


1. New qualitative and quantitative data about sources of a natural and man-caused infrasound.
2. New data about the time-space characteristics of wave processes provoked in atmosphere by such sources.
3. The numerical methods of the analysis and calculation of infrasonic fields from investigated sources.
4. Methods and hardware complexes for application in different areas of industry and in systems environment monitoring
5. The norms and marginal doses of infrasonic effect;

Volume of work.

The main stage includes:


· Development of techniques and principles of construction of instrumentation for monitoring of infrasonic fields.
· Development and creation of a measuring complex for realization of long-time regime observation of infrasonic fields.
· Realizations of long-time regime observations of infrasonic fields from man-caused sources on mines of Kyrgyz Republic and Russia.
· Comparative observations data analysis and obtaining the information about the time-space characteristics of infrasonic fields from man-caused sources on ore mines of Kyrgyz Republic and Russia.
· Detections of general legitimacies and distinctive features of infrasonic disturbances from man-caused sources for development of identification tags.
· Researches of influence of local conditions on propagation of an infrasound.
· Realizations of observation of infrasonic fields on Toktogul Hydro Power Stations.
· Data analyses of observation on Toktogul Hydro Power Stations and estimation of the time-space and power characteristics of infrasonic fields.
· Realizations of observation by an infrasound provoked in mountains.
· Researches of an infrasound provoked in mountains and estimation of its amplitude-frequency characteristics, features of originating and propagation. The participants of the suggested project are scientists who made remarkable contribution in research of different geophysical fields from man-caused and natural sources.

Adushkin V.V., Kulikov V.I., Goncharov A.I.,Syrnikov N.M. and Evmenov V.F. are authors of great number of works about estimations of infrasonic waves influence on environment.

Sobisevich L.E., Sobisevich A.L., Brednev S.P. and Mazurin N.F. for many years research infrasonic fields from natural sources. A lot of results of their work are published in domestic and foreign literature.

Harlamov V.A., Burchik V.N. and Rybnov Y.S. work on problems of receive and identification of infrasonic fields coming from sources of different nature. They have a great experience of field works aimed on registration of infrasonic coming from blasting (industrial and other) sources. They have published materials on these researches. They make session observations of background characteristics of infrasonic in different regions of Russian Federation. Besides they work on problems of infrasonic impact on environment in regions with well developed industrial infrastructure.

Tupchy Y.G., Yakovenko V.S., Bragin V.D. for many years research geophysical fields from man-caused and natural sources on the territory of Kyrgyz republic.

Stubarev V.M., Mamedov M.H., Buzlov A.G. have a great experience in development of different electronic hardware for scientific researches and data collection systems.

Personnel of the project participants allows to be assured that project will be fulfilled on a high scientific and technical level.

During fulfillment of works aimed on studying of infrasonic from man-caused and natural sources there will be used original algorithms, methods and approaches to development of data collection and analyze systems developed by the authors. Basement of these methods is a multipoint (space distributed) synchronous measuring of infrasonic and parameters of bottom layer of air(speed and direction of wind, temperature and humidity, atmosphere pressure and etc). It will allow to estimate the source coordinates, it’s intensity, radio path characteristics and etc.
