The results of experimental research the inverse problem to retrieve of the velocity both and spatial position of the turbulent current through the analysis of fluctuation spectra of the acoustical signals of different frequencies. Conditions and accuracy of the inversion by multi-frequency signal, passed on the acoustical path crossed the turbulent current are discussed. The research has been done in echoless chamber with air flow as a turbulent current. In spite of general physics type of this research could be implemented in atmosphere acoustics, aeroacoustics and ocean acoustics
