摘要
利用ＰＶＣ、ＮＢＲ、无机物等制成了一种吸声材料，该吸声材料具有低频吸声系数高、成型加工简单、成本低等优点。讨论了ＮＢＲ用量、厚度、容重等因素对吸声材料的吸声性能的影响。
The new sound-absorbing material made from PVC,NBR and other inorganic compounds was studied. This material has good sound-absorbing properties in the low frequency. Additional1y, the effects of parameters such as component and morphology were discussed.
