The knowledge of acoustic is very required because it is related to sound and is highly essential to maintain the peaceful surrounding of our environmental conditions. One of the branches of science and engineering is the architectural acoustic and it is needed for the maintaining the good sound level in the buildings. Noise level has its effect on the human health. Researchers are trying their level best to minimize sound pollution level to a minimal to reduce noise pollution for the benefit of mankind. There are various means and measures to control sound quality at any space for the required environment. Many new materials as well as methods are available to improve upon the sound level to maintain peaceful environment. For the noise control in the rooms, sound absorbing materials are used. Fibrous medium and porous foam materials are used to control noise for different places. Designers are now-a-days using various beautiful textile materials which are acoustically transparent t...
WOVEN FABRICS COMBINATION FOR ACOUSTICS OF BUILDING INTERIOR
TJPRC, 2014
Today much importance is given to the acoustical environment. Noise control and its principles play a major role in creating an acoustically pleasing environment. Since long the textile materials are use for wall covering. Today combinations of fabrics are use for wall covering not only for decorative purpose but also for reduce the intensity of sound and brought down for acoustic purpose. Textile materials are fibrous and porous materials have been accepted as sound absorptive materials. This research paper woven fabric are used as cover material and combined with of nonwoven fabric as backing material to study the sound absorption behavior. Also the effects of different fabric properties on sound absorption have been studied. Such types of materials with different structure are promising for home interiors, office interiors, and automobile interiors due to their good sound absorption and insulating properties.

Environmental pollution in our daily life because of noise is an increasing public health concern. We designed and woven with staple-and draw-textured yarns, for sound absorbance purposes. For wefts and warps, two different thicknesses of the thick staple-yarn and thin draw-textured filament yarn were used. The prepared fabrics were classified in porous, medium, and dense, on the basis of their densities and air permeabilities, and the sound absorption coefficients of the fabrics were found to be linearly related to the air permeability. The sound absorption coefficient determined by the impedance tube method was higher for porous fabrics compared with that for dense fabrics in the high frequency region. By the reverberant field method, the sound absorption coefficients for all fabrics were highest in the low frequency region. Porous fabrics exhibited a shorter reverberation time and a higher sound absorption coefficient than dense fabrics owing to their good sound absorption property.
Optimisation of the Sound Absorption of a Textile Material
DYNA, 2020
Textile structures such as non-woven fabrics have been used as acoustic insulation since ancient times, however, including a fabric layer can significantly improve the aesthetic appearance. This article studies the influence of the filling threads that are commonly used in upholstery or quilted fabrics. The novelty focuses on evaluating the influence of these threads, in combination with different structural variables, on the acoustic insulation they provide. With the structures that incorporate filler threads, it is intended to offer optimized acoustic solutions that incorporate design, this will allow the development of products that can be used in the insulation of premises contemplating their decorative appearance, and not being used as a merely structural element. This article shows how thanks to the design of experiments it has been possible to define the productive variables of the fabric (warp and weft density, presence of quilting threads, etc.) that optimize the acoustic c...
NONWOVEN ACOUSTIC TEXTILES – A REVIEW
Noise or unwanted sound is perceived as disturbing and annoying in many fields of life. This can be observed in private as well as in working environments. Noise control and its principles play a major role in creating an acoustically pleasing environment. This can be achieved when the intensity of sound is brought down to a level that is not harmful to human ears. One of the techniques to achieve pleasing environment is by absorbing sound. Fibrous and porous materials have been accepted as sound absorptive materials. This paper reviews and describes how the different fiber parameters, surface treatment, film covering, forming process, physical parameters, etc. of materials influence the absorption behavior.
Materials
Utilizing textile-based acoustic materials can be considered basically from two points of view. First, it may be used as a sound absorbing material. Second, it may be used as a decoration that gives the surrounding area a new artistic appearance. To improve the acoustic possibilities of any woven fabric, it is necessary to study the influences of yarn characteristics and the internal structures of weave interlacement. To understand the impact of the yarn on the fabric, the samples were prepared using only polyester fiber as textured, twisted, and staple yarns. Regarding this experiment, the basic weave’s structure type, such as plain, rib, sateen, and twill, were used. Overall, 16 woven fabrics were prepared. The investigation was performed in the range of low to medium acoustic frequencies. The experiments were conducted in an anechoic chamber. Compared to other yarn types, fabrics formed from textured polyester yarn had higher sound absorption properties. Moreover, the observed re...

Noise pollution from the environment may wreak havoc on a person’s wellbeing. Numerous sound-absorbing materials are employed to address these issues, one of which is textile-woven fabrics. In this study, 12 woven textiles with four different weave structures (plain, rib, sateen, and twill) and those formed from three distinct polyester yarns were evaluated for their sound absorption properties using an impedance tube. The study was conducted within the range of 80–5000 (Hz) frequency. Part of the investigation was measuring different layers of woven fabrics under three different measuring conditions. Firstly, only woven fabrics were evaluated. Following that, woven and nonwoven textiles were measured. The third variant, in addition to the woven fabrics, included an air gap. In addition, this study includes tests and analyses of the effect of roughness and porosity of the fabric structure on the effectiveness of noise reduction by woven fabrics. The absorption capacity of plain fabr...
Influence of designs of weaves on acoustic attenuation of fabrics
Journal of Industrial Textiles, 2018
The results of acoustics tests of different structure woven fabrics are presented. The researches were performed in the aeroacoustic anechoic chamber. Ten fabrics were tested (four of them with honeycomb 3D design) to check their acoustic properties. The tests were conducted inside lower and medium acoustical frequency zones. The presented studies showed that all fabrics with honeycomb weaves had much less attenuation than other fabrics, mostly due to less dense structures at higher thicknesses and more open internal structures. Having analyzed the obtained results, some comments are shown and possibilities of using such woven structures are proposed.
This study investigated the absorptive properties of nonwoven cotton and Polylactic acid materials. Fibrous nonwoven materials convert sound that passes through them to heat energy. The nonwoven materials used in this study are batts and fabrics made from 100 percent cotton and 100 percent polylactic acid fibers, which are all natural fibers that are degradable and are environmentally friendly. The focus of this study is to; ascertain the effects that fiber type and layering arrangements have on the acoustical absorptive properties of nonwoven. Layers of PLA and cotton batts of various order in 100, 50-50, 25-75, and 75-25 percentages were tacked together; in-order to establish the acoustical properties of various layering arrangement at different frequencies. The method used for measuring the acoustical properties of the batts and fabrics used in this research is the impedance tube method, whereby; sound absorption coefficient is determined at each frequency in accordance with the ASTM 1050-08 standards. The analysis of the acoustical data provided shows that eight (8) layers cotton batts absorbs better than cotton fabric and Polylactic acid batts and fabric. The results of this study shows that physical elements such as; fiber type, fiber size, layering order, fiber cross section, material thickness, density, airflow resistance and porosity are important factors in determining the absorption behavior of nonwovens materials. INTRODUCTION In the present age, noise is an ever-increasing problem everywhere in the world, especially in the developing countries where the Government regulation is not been enforced against public disturbance, sources of noise are now on the increase and they are steadily growing louder. Noise pollution was once termed an irritating but harmless nuisance but it has now become a major threat to health and well-being. Noise is public nuisances which causes undue distractions, contributes to health problems, stress and eventually lower productivity. This explains why most people love quiet environment and are willing to pay for it. In places such as homes, hospitals, concert halls, schools and learning environment where one expects to be quiet are not exempted from noise pollution in some places.
