资源简介：
An acoustic sound absorptive panel or block is provided that is made from a plurality of materials and volumes selected such that each discrete volume of material has a sufficiently different sound absorption profile， resulting in a system that provides better overall sound absorption of traffic noise from motorways and railways in a practical and cost-efficient manner.
