【摘要】 本文通过测试泡沫铝的吸声系数来研究泡沫铝的吸声性能。结果表明 ,泡沫铝具有较好的吸收性能 ,其吸声系数对于频率很敏感 ,大约在 10 0 0Hz时吸声系数出现一个峰值。吸声系数随孔结构的变化有一定的规律性更多还原

【Abstract】 The sound absorption property of aluminum foam was studied and analyzed by testing its sound absorption coefficients.Experiments show that aluminum foams have better sound absorption property,its coefficients are influenced by frequency and pore structure and reach to a extremum in about 1000Hz.更多还原
