摘要
采用传递矩阵法计算由穿孔板,双层多孔材料及背板组成的夹层复合吸声材料的吸声系数,利用该方法分析多孔材料厚度及穿孔板穿孔率对复合吸声结构吸声性能的影响,优化该复合结构吸声性能,并用实验验证。结果表明:传递矩阵法在中低频计算精度较高。该复合吸声结构在较宽频带有良好的吸声效果。
Based on the transfer matrix method, the sound absorption coefficient of the sandwich composite sound absorption material composed of perforated plate, double layer porous material and back plate is calculated. The influence of the thickness of the porous material and the perforation rate of perforated plate on the sound absorption performance of the composite sound absorption structure is analyzed by the method. The sound absorption performance of the composite structure is optimized and the calculation results are verified by experiments. The results show that the transfer matrix method is of high accuracy in the medium and low frequency calculation. The composite sound absorption structure has a good sound absorption effect in a wide frequency band.
