Experimental Study on the Sound-Absorption Capability of Nonwoven Sound-Absorbing Material under Different Density Combination
In this paper, the influence of different combination of different density of nonwoven materials on the sound-absorption capability is studied through the serial experiments. The results show that the structure with low density on the surface material and dense density in the middle of the material will have better capacity in absorbing sound.
