覆面层对玻璃棉吸声性能的影响
Effects of covering layers on the sound absorptive property of a fibre glass board
  
中文摘要:
      本文通过试验探讨了四种覆面展对玻璃棉板吸声性能的影响。结果表明;在不同的频率范围,铝箔及穿孔铝箔面层对材料的吸声性能影响较大,而玻纤薄毡和橡胶面层的影响较小。
英文摘要:
      This article presents the experimental results concerning the effects of four types of covering layers on the sound absorptive property of a fiber glass board. They show that at different frequency ranges, the effects of the aluminum film and the perfo-rated aluminum film on their sound absorptive properties are significant while those of the rubber film and the thin glass fiber covering layer are relatively small.
