本文对基于二次剩余序列的声学结构的吸声性能进行实验研究，并定性分析了它的吸声机理．研究表明，除了结构振动所产生的损耗之外，更重要的吸收源是结构表面由于声干涉所形成的附加声阻抗的影响．
In this paper, the acoustic performance of the acoustic structure based on the quadratic residual sequence is experimentally studied, and its sound absorption mechanism is analyzed qualitatively. Studies have shown that, in addition to the losses caused by structural vibrations, the more important source of absorption is the effect of additional acoustic impedance on the structural surface due to acoustic interference.
