中文摘要:
      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。
英文摘要:
      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.
