  •  Jing Li    


Nonwoven has got fast developed and widely used in the range of the world, while it is mainly used is as the auxiliary
materials of perforated plate for its sound absorption capability in our country. In this paper, we summarized the relationship between the property parameters of the non-woven materials and their sound absorption capability. Experiments and theory analysis proved that the thickness of non-woven materials was the most influencing factor on their sound absorption
