摘　　要：泡沫铝板后设置一定的空腔深度,可获得在中高频段较宽频带的吸声性能。文章介绍采用在泡沫铝板背面复合薄膜形成复合板吸声结构,可使其低频吸声性能获得较大幅度提升。A considerable wide absorbing band in the midand highfrequency range can be obtained when an air space is added behind an aluminum board. This paper introduces the foamed aluminum board with a back membrane structure, which effectively improves the low frequency absorbing property. 
