A Study on the Sound Absorption Characteristics of the Multilayer Microperforated Panel
摘要
Abstract
In the paper, the design and sound absorption characteristics of the multi-layer micro-perforated panel with large back cavity are studied. Based on the electric-force-acoustic analogy algorithm, the micro-perforated panel could be equivalent to the circuit system of resistance-capacitance series. But as the depth of the back cavity increases, the electric-force-acoustic analogy algorithm grows complicated for analyzing the sound absorption characteristics, and the calculation accuracy is low. In view of this, a transfer matrix method is proposed. The accuracy and effectiveness of the proposed method were verified by numerical examples with the finite element method.关键词
