资源简介：
A sound attenuating material having a homogenous mixture of an organic manmade fiber， an inorganic man-made fiber， a binder， and a cellulose material wherein the organic man-made fiber is polyester， the inorganic man-made fiber is fiberglass， and the binder is a thermo-setting resin. A sound attenuating composite is defined by the sound attenuating material and a ground EVA or a mixture of EVA and one or more recycled materials to define a gradient density sound attenuating composite material. Further， the gradient density composite may optionally include a polyfilm upon which the ground EVA or recycled materials may be disposed or two layers of polyfilm to surround the EVA or EVA mixture. The EVA may be pure EVA or may include a mineral fill.
