Recent Advances on Textiles‐Based Sound Absorption Materials

This review has summarized recent advances in textile‐based sound‐absorbing materials, with a primary focus on fiber selection, fabric architectures, acoustic modeling, and performance optimization. The acoustics of both natural and synthetic fibers were discussed, and highlighting the trade‐off between sustainability and manufacturing controllability. As textiles, woven, knitted, and nonwoven fabrics exhibit distinct acoustic characteristics, while their integration into multilayer and hybrid composites enables improved broadband sound absorption through the coupling of porous dissipation, resonance, and damping mechanisms. Existing sound absorption models for different textile structures have been critically evaluated. Although these models provide useful guidance, their predictive accuracy is often limited by strong frequency dependence and insufficient consideration of complex hierarchical structures. Therefore, structure–property relationships remain a key challenge in textile acoustics. Performance optimization strategies, including structural design, multilayer configuration, and functional modification (e.g., nanofibers, damping layers, and surface treatments), were also reviewed. It has demonstrated their effectiveness in improving low‐frequency absorption and multifunctionality. Overall, this review provides a comprehensive framework for designing next‐generation acoustical textiles that are lightweight, broadband, and application‐oriented.
