摘要： An acoustic damping building material (100) comprising an acoustic damping layer (118) secured to at least a portion of a substrate (110). The acoustic damping layer comprises at least two media wherein the at least two media are configured such that the acoustic damping layer comprises at least one direct energy transmission pathway and at least one indirect energy transmission pathway through the acoustic damping layer to the substrate.
