✦ Synopsis

The covering-domain method is adopted to calculate "rst the interior sound "eld of a complex-shaped cavity sti!ened with stringers, then the in#uence of an appended mass on the complex cavity wall is further analyzed based on the covering-domain method. Besides, the method is applied to analyze acoustic shape sensitivity of complex-shaped cavity. Combining a speci"c cavity, we calculate the corresponding acoustic shape sensitivity when every dimension of the cavity varies respectively. This will provide theoretical instruction for dynamic structural modi"cation of the complex-shaped cavity.
