This research is the next stage of research related to extraordinary features of Special Granular Structures. Some properties of granular structures, e.g. the changing of structure of the material, once it is submitted to internal underpressure in a sealed container, led the authors to believe that the acoustic properties may also change with pressure. Performed research regarding material sound absorption of investigated granular structures shows new potential possibilities of their application and confirms, that one can control acoustic properties of such structures.
