Design and optimization of sound package using FE-SEA numerical reverberation method
摘要
Abstract
To solve the low efficiency problem of the conventional sound package, the FE-SEA numerical reverberation method is applied in the design and optimization of sound packages in the whole frequency domain. Two types of sound package with and without air layers are designed and optimized. The FE-SEA numerical reverberation method is used to calculate sound transmission loss. The thicknesses of the air layers of the sound packages are defined as design variables. The optimization results reveal that the sound package with air layer has better acoustic performance than the one without air layers, and the sound transmission loss can be raised 2-6 dB after optimization. The research results have important guiding values for ship sound package design in actual engineering.关键词
