In order to reduce noise of automotive interior acoustic environment, based on acoustic properties of laminated materials and waterproofing membrane material characteristics, adopting spot test data, combined with interior design experience, acoustic performance, cost and operational characteristic of waterproofing membrane materials and combination lining materials of three main doors are contrasted. The results indicated that waterproofing membrane of X-PE materials meets the design requirements. It shows good effect in sound insulation and sound absorption. High rigidity materials can improve the efficiency of sound insulation in composite materials. It provides reference for new materials used in function expansion of door trim pieces.
