【摘要】 本论文对泡沫铝的隔声性能作了研究和分析。试验证明 :泡沫铝的隔声性能对频率和孔结构有很强的敏感性 ,在 0 12 5～ 16kHz范围内均具有较好的隔声作用 ,孔径为 1 0mm、孔隙率为 70 %的泡沫铝试样的隔声效果最佳更多还原

【Abstract】 The sound insulation property of aluminum foam was studied and analyzed Experiments show that sound insulation property of Al foam iS very sensitive to the frequency and pore structure Al foam has good sound insulation property in 0 125～16kHz When Al foam body have pore diameter of 1 0mm and porosity of 70%,its sound insulation property is the best更多还原
