Abstract :The non-linear paradigm clams, that many processes in open, non-linear, dynamical systems, which caused by the non-stationary, powerful sources, are appeared to be short-time, non-linear, ultra-wideband and fractal ones. The acoustic signals created by the Chelyabinsk meteoroid fall were shown to be namely ones of them. Using a new fractal analysis method called as ‘Dynamical Fractal Analysis’, the fractal properties of these signals were investigated. The corresponding numerical characteristics were estimated and discussed.
