摘要/Abstract

摘要：基于传统亥姆霍兹共鸣器的隔声特性，运用传递矩阵法分层推导了基于二阶共振的亥姆霍兹共鸣器的等效阻抗，并结合有限元仿真对二阶亥姆霍兹共鸣器的隔声特性进行了探究，验证了二阶共鸣器共存在两个隔声频段，且通过调节几何参数获得了优异的隔声效果，在隔声降噪的声学应用中具有一定的研究意义.

Abstract: Based on the sound insulation characteristics of the traditional Helmholtz resonator, the equivalent impedance of the Helmholtz resonator based on second-order resonance is derived by using the transfer matrix method layering, and the sound insulation characteristics of the second-order Helmholtz resonator are studied in combination with finite element simulation. It is verified that there are two sound insulation bands in the second-order resonator, and excellent sound insulation effect can be obtained by adjusting the geometric parameters. It has some research significance in acoustic application of sound noise reduction.

Key words: Transfer matrix method, Second-order Helmholtz resonator, Double sound-insulated bands, Finite element simulation
