This paper has presented the situation of intake silencer research and application and expounded the intake noise engendering cause and the basic theory on controlling the intake noise . then a research established in the accurate determination of resonance frequencies of different kind of helmholtz resonators is done . according to different assumptions , four kind of mathematical models are established , and the relations between them are discussed
本文介绍了进气消声器研究与应用的现状与发展，阐述了进气噪声产生机理及控制的基本理论，研究了helmholtz共振型进气消声器的原理，立足于helmholtz共振型进气消声器的共振频率的准确确定，建立了两类四种共振腔模型，并讨论了它们之间的相互推演关系。
We regard every layer of grain as a lot of helmholtz resonators in parallel , and regard different layer of grains as the paralleling resonators in series . the grain is a combined resonator in series and parallel . based biot ' s theory of acoustic propagation in porous media this paper applies johnson ' s model to grain media
一定厚度的粮食可看作是一种组合式共振吸声结构，每层认为由许多个单独亥姆霍兹共振腔并联而成，而层与层的共振腔为串联关系，表现为共振性吸收，出现了共振吸收峰。
