The invention provides a sound absorption and insulation pad and a preparation method and application thereof. The sound absorption and insulation pad comprises a surface layer, a middle layer and a bottom layer which are sequentially arranged from top to bottom, and the surface layer is made of high-density non-woven fabric. According to the sound absorption and insulation pad, on the premise that the overall thickness and surface density are not increased, the overall sound absorption performance of the sound insulation pad in a wide frequency band is kept.

    本发明提供了一种吸音隔音垫及其制备方法和应用。本发明的吸音隔音垫,包括从上至下依次设置的表层、中间层和底层,所述表层为高密度无纺布。本发明的吸音隔音垫,不增加整体的厚度和面密度的前提下,实现了隔音垫整体在较宽频段内保持较高的吸声性能。
