摘要
吸声材料是吸声降噪的主要材料,通过对基于不同聚醚种类的聚氨酯硬质泡沫塑料进行降噪性能测试,讨论了材料的结构、抗压强度及厚度对降噪效果的影响。
Acoustic absorption material is the main material for acoustic absorption and noise reduction. In this paper, polyurethane rigid foam which is based on the different kind of polyether has been made. And according to the noise reduction properties testing results, the effects of the structure of material, compression strength and the material thickness have been discussed.
