| Abstract: | 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. |
