Low Frequency Sound Absorption by Optimal Combination Structure of Porous Metal and Microperforated Panel
The combination structure of a porous metal and microperforated panel was optimized to develop a low frequency sound absorber. Theoretical models were constructed by the transfer matrix method based on the Johnson—Champoux—Allard model and Maa’s theory. Parameter optimi...
