摘要
为了有效隔断中、低波频率的噪声,按照一定的配方及其成型工艺,制备了一种超薄、轻量、柔韧的铅纤维/聚氯乙烯复合材料,分析研究了其隔声性能,并对其结构及抗噪声机理等进行了讨论。测试结果表明:这种材料对中、低频率的噪声的隔声量高达15dB以上。
Lead fiber/EPVC composite material, which is a very thin, lightweight and flexible material is fabricated to improve sound insulation at low and middle frequencies efficiently according to some molding process parameters. The sound insulation property is investigated and analyzed, and its structure and noise resistant principles is also discussed. The test result shows that the sound insulation index of this kind of material at low and middle frequencies obtains over 15dB.
