The invention discloses an automobile carpet sound insulation pad and an automobile. The sound insulation pad comprises a carpet surface layer, a carpet sound absorption and insulation layer and a carpet flame-retardant layer which can be assembled in a layered mode. The carpet surface layer comprises a needle-punched PET fiber and chinlon PA66 fiber composite fabric layer, the carpet sound absorption and insulation layer comprises a dual-density cotton felt layer, and the carpet flame-retardant layer comprises a thermoplastic polyolefin elastomer TPO composite EVA layer. The needle-punched PET fiber and chinlon PA66 fiber composite fabric layer is prepared by mixing PET fibers with the fiber diameter of 0.04-0.06 mm and 12-18% of chinlon PA66 fibers, the thickness of the needle-punched PET fiber and chinlon PA66 fiber composite fabric layer is 6-8 mm, and the material gram weight of the needle-punched PET fiber and chinlon PA66 fiber composite fabric layer is 450-560 g/m < 2 >.
