Abstract

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.
