Abstract
In recent years, noise pollution has been recognized as a major environmental challenge, and its destructive biological and psychological effects on humans and other living organisms have been demonstrated. The use of sound‑absorbing materials as an efficient method for noise reduction holds a special place in acoustic engineering. Among these materials, textile nanofibers, due to features such as ultra‑fine diameter, high specific surface area, and large porosity, can effectively improve the acoustic properties of materials without increasing weight and thickness. This paper also examines the mechanisms of sound absorption by nanofibers, reviews recent advances in the design and optimization of nanofibrous structures, and surveys their novel applications in noise reduction. The review results indicate that designing these structures by controlling parameters such as polymer type, fiber geometry, porosity level, layer thickness, and the method of combining with nanoparticles plays a decisive role in optimizing sound‑absorption performance across different frequency ranges. These findings provide a prospect for designing advanced acoustic absorbers with targeted frequency performance suitable for urban and industrial environments.
