隔聲

In theis paper, the characteristics of sound insulation of a typical aicraft sidewall structure have been investigated. 研究了典型飛機(jī)壁板結(jié)構(gòu)的隔聲特性。

Woven fabrics have sound proof property, weaving high density multi-layer fabric can get good sound proof property. 結(jié)果表明機(jī)織物具有的隔聲性能以高密度多層結(jié)構(gòu)織物的隔聲效果最好。
