结果表明，吸声材料与吸声结构的有机结合显著提高了结构的吸声效果，拓宽了吸声频带宽度。
The results show that the appropriate combination of sound absorption materials and sound absorption structures can improve the sound absorption effect, and the absorption broadband is widened.
随着孔隙率、孔径的减小，多孔铝的共振吸声系数有所下降，吸声频谱曲线向低频方向移动，且频带宽度展宽。
When the porosity and pore diameter reduced, the sound absorption curve moved to the low frequency zone and the frequency bandwidth increased at the same time.
