摘要对以压合丝瓜络为主要原材料制成的吸声板进行试验，结果表明该板吸声效果良好，一定范围内吸声系数与板材密度成正比；改变材料背部空腔深度，能改善材料在低频范围内的吸声性能；将不同密度的吸声板组合形成复合吸声板，可提高其吸声特性。

Abstract： This paper tested and studied the acoustic board mainly made of model pressing loofah. It was found that the model pressing loofah acoustic board has favorable sound absorption property and its sound absorption coefficient within a certain range is proportional to the board density; changing the cavity depth on board back could improve the sound absorption effect within the low frequency range; pressing acoustic boards of different densities together could increase the sound absorption property of the board.

Key words： model pressing loofah sound absorption board sound absorption coefficient standing wave tube
