摘　　要：通过阻抗管法研究了聚酰亚胺(PI)、三聚氰胺(MFF)和聚氨酯(PU)3种泡沫材料对声音的吸收特性。结果表明:与MFF和PU泡沫材料相比,PI泡沫材料具有优异的吸声降噪性能;随着材料密度的增大,3种泡沫的吸声降噪性能都有相应提高。The sound absorption characteristics of the polyimide(PI) foam, the melamine(MFF) foam and the polyurethane(PU) foam were measured by the impedance tube method. It was found that PI foam had better sound absorption and noise reduction performance than MFF foam and PU foam at the same density. At the same time, with the increase of density, the sound absorption and noise reduction performance of the three kinds of foams had been improved correspondingly.
