2010 MECHANICS AND CONTROL   unpublished
This paper presents the results of the expanded research program on sound absorbing properties of granular materials (granular polypropylene, foamed polystyrene, gravelite, rubber, mineral wool, and high-silica sand) being often applied as sound absorbing cores in double-wall partitions of constructions limiting noises of machines and devices.
