The invention provides a building method of an acoustic material CAE simulation parameter database. A definite procedure and method for obtaining data involved in a current building process of an acoustic model of a whole vehicle and parts thereof are provided, the acoustic parameters and sound absorption-insulation properties of the materials are integrated, acoustic simulation software is applied to conduct debugging, reliable material CAE parameters are obtained, integrated and classified into the database, and it is guaranteed that the database is clear in module, and readable and facilitates consulting. The CAE simulation parameter database can be applied to a modeling process in the level of materials, the level of parts and the level of the whole vehicle, the modeling efficiency andprecision are greatly improved, and thus the efficiency of product proposing is improved.
