Influence of compressive ratio and density on sound absorbing property of foamed aluminum made by bubbling method has been studied and compared with that of Japanese sample.
研究了压缩率和密度对发泡法制备的泡沫铝样品吸声性能的影响，与报道的日本用发泡法制备的泡沫铝样品的研究结果进行了比较。
The results show that the best sound absorbing property can be obtained at a critical compressive ratio 40%, The sound absorbing property increases with the decrease of density.
结果表明：压缩率达4 0 %时，可获得最佳吸声效果，随密度的减小泡沫铝吸声性能增大。
The checked result shown that the prepared foam has the excellent property of absorbing and sound insulation function.
检测结果表明制得的泡沫具有优良的吸隔声性能。
