Sound wave absorption properties of multi-layers of different woven fabric structures

Nowadays, acoustic health is a priority issue in homes and offices. To address the problem, a variety of sound-absorbing materials are used, one of which is woven and nonwoven fabrics. This paper focused on the sound absorption analysis of two different woven fabric structures as an increasing layer and with base material nonwoven fabric. The fabrics' sound absorption properties were determined using an impedance tube across 80–5000 (Hz) frequencies. The result demonstrated that the absorption of sound energy through plain fabric decreases as the number of layers was increased. On the other hand, in the case of a sateen fabric structure, the absorption of sound energy increases with the number of layers. The absorption capabilities of sateen fabrics are particularly impressive in the high-frequency ranges. The double and triple layers of plain fabric, on the other hand, demonstrate high sound absorption results at frequencies below 1000 Hz in comparison to sateen fabric.
