Variably Tuned Helmholtz Resonator可调频的亥姆霍兹共振器
Sound absorption advanced in this dissertation is different from traditional structure for sound absorption. The broadband resonance sound absorption structure for low frequency on the basis of Helmholtz resonator, and the rigidity neck is superseded by the tube.
与传统的吸声结构不同,本文提出以赫姆霍兹共振器为基础,用软管代替刚性瓶颈,构成低频宽带共振吸声结构。
