The quest to acquire improved sound absorbing textiles by optimizing the quality and quantity of the material has been an ongoing area of research. Several studies substantiate that fabrics, specifically of the nonwoven type, demonstrate comparably better noise reduction. In several instances, the nature and orientation of the fibre within the fabric plays a major role on the overall absorption. However, the interaction of nonwoven fibres with the acoustic waves is a research area that needs more attention. In the present study, the nonwoven sample has been characterized for determining its potentiality as an acoustic absorbent. Effective properties have been parametrized to understand its impact on the sound reflection and absorption characteristics. Experimental analyses has been carried out using the Impedance Tube test for a frequency ranging from 50 Hz to 6.4 kHz. The results discussed convey a key contribution to enhance the research work on the nonwoven fibre characterization and its influence on absorptivity. With the intent of producing quieter spaces and conveyances, nonwovens can act as efficacious acoustic absorbents. Their increasing reliance to curb noise off the industrial, transport and built environments has been the main motive of this study. The development of cost effective fabrics that essentially act as sound absorbents will form a part of the future work.
