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 results show that the different incidence angles of acoustic signals influence the measured sound absorption properties of a textile.
利用基于纺织品的声学材料基本上可以从两个角度来考虑。第一，它可以用作吸音材料。第二，它可以用作一种装饰，赋予周围区域一种新的艺术外观。为了提高任何机织织物的声学性能，有必要研究纱线特性和织物交织内部结构的影响。为了了解纱线对织物的影响，仅使用聚酯纤维制备了变形纱、加捻纱和短纤纱样品。关于这个实验，使用了基本织物的结构类型，如平纹、罗纹、缎纹和斜纹。总共制备了16种机织织物。研究在低至中频声学频率范围内进行。实验在消声室中进行。与其他纱线类型相比，由变形聚酯纱制成的织物具有更高的吸音性能。此外，观察结果表明，声信号的不同入射角会影响纺织品的测量吸音性能。
