摘要
为了改善薄层声学材料低频隔声性能较差的缺点,本文研究了附加多质量块的单胞薄膜型声学超材料的隔声性能,利用有限元方法分析了附加多质量块的单胞薄膜型声学超材料的传递损失及模态特征。研究结果表明:通过附加多质量块改变了原单质量块所具有的模态特征,其表现为传递损失的第一个谷值所对应频率更低,第二个谷值(特指传递损失为零的谷值)对应频率更高,因而实现宽频范围内的较高隔声量。
Multi-mass of membrane-type acoustic metamaterials was studied, in order to obtain better sound insulation performance at low frequency. Finite element analysis was employed sound transmission loss(TL) for membrane-type acoustic metamaterials. The present work was described as follows: multi-mass compared to a single-mass has better sound insulation properties between the two valley of frequency. Specifically, the first valley of TL of corresponding to the frequency is lower, and the second valley of TL(value of zero) of corresponding to the frequency is higher.
