Abstract
The results of researches related to acoustic efficiency of shredded nonporous polymeric structures from the solid waste used as a
 part of bulk noise-attenuating modules are presented in this work. The air-tight structures of materials subjected to corresponding
 technological procedures of crushing with formation of semi-finished products, in particular, in the form of rubber crumb, film
 chips and polymeric granules are considered. The reached improvements of sound-absorbing efficiency of bulk noise-attenuating
 modules’ model samples are analyzed. Ecological and cost advantages of use of the noise-attenuating devices containing shredded
 porous sound-absorbing structures have been noted.
