The Use of Fabrics to Improve the Acoustic Absorption: Influence of the Woven Fabric Thread Density Over a Nonwoven

Abstract: Noise is frequently unnoticed, but it is one of the causes of unhealth for human beings reducing people’s quality of life. There are many materials that can be considered as acoustic absorbents. Textiles can be used to both improve the acoustic quality of and to decorate the room where they have been placed. In this study, we used some fabrics with 15, 20 and 30 ends/cm and 15, 20 and 30 picks/cm. The acoustic absorption coefficient was measured when the fabric was added as a resistive layer on top of a nonwov… Show more

“…Woven fabrics are fibrous materials and classified as porous material. Observed by other researchers [ 5 , 6 ], the effectiveness of woven materials for the application of sound absorption is not as effective as nonwoven materials. Specifically, some studies [ 7 , 8 ] show there are problems with low frequency sound absorption for the cases of many porous materials including textiles.…”

“…The nature of the fiber type influences the sound absorption of any material and the sound absorption is enhanced by a lower yarn linear density and finer yarns, as described in [ 6 , 11 ]. Segura-Alcaraz et al [ 5 ] explain that a jute material has better sound absorption properties than other synthetic materials. Moreover, sound reduction using jute fibers at lower frequencies is more effective in comparison to higher frequencies, besides other yarn characteristics, as mentioned in [ 12 ].…”

“…Multilayered materials are widely used to improve the efficiency of fibrous absorbers [3739]. When in combination of a woven fabric layer and a nonwoven, the fabric acts as a resistive layer that modifies the absorption of the obtained composite material [4042]. Besides, it has been observed that in double porosity absorbent materials, the hole profile has a strong influence so a progressive decrease of the meso-porosity as the wave penetrates inside the material increases the absorption coefficient in a wide frequency band [43].…”
