The results obtained were applied to refine the observed properties of the fundamental f-mode in the Sun. The response of the ionosphere to the acoustic radiation of a terrestrial generator, depending on the shape of the signal and meteorological parameters by local measurements from spacecraft, is investigated. According to many years of space experiments aboard the SOHO solar laboratory, the analysis of averaged long-term series of observations of the acoustic oscillations of the Sun in the vicinity of the acoustic frequency of the cutoff. Computer codes have been created to describe the propagation of waves in an isothermal solar atmosphere, based on reflection. The technology of controlled generation of atmospheric infrasound waves in the surface atmospheric layers based on the parametric effect has been improved. Information technology for estimation of noise signal intensity in the presence of noise is developed. The stationary terrestrial controlled acoustic emitter of parametric type has been improved.
