댐핑 발포체 물질을 제1 기판 표면과 제2 기판 표면 사이의 공간 내부에 위치시키고 그에 걸쳐 있게 함으로써 차량의 중공 공간 또는 공동과 관련된 소음 및 진동 특성을 감소시키기에 유용한 조립체, 방법 및 시스템이 제공된다. 댐핑 발포체 물질은 제1 영역 및 제2 영역으로 이루어지며, 여기서 제1 영역은 -10℃에서의 E' 값이 제2 영역의 -10℃에서의 E' 값보다 더 낮고 25℃에서의 E' 값이 제2 영역의 25℃에서의 E' 값보다 더 높고; 제2 영역은 가변 단면 폭을 갖는다.

    Assemblies, methods and systems useful for reducing the noise and vibration characteristics associated with hollow spaces or cavities of vehicles by positioning damping foam material within and spanning the space between a first substrate surface and a second substrate surface. The damping foam material is comprised of a first region and a second region, wherein the first region has an E′ value at −10° C. that is lower than the E′ value at −10° C. of the second region and an E′ value at 25° C. that is higher than the E′ value at 25° C. of the second region; and the second region has a variable cross-sectional width.
