| 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. |
