Noise pollution has become a critical challenge, impacting human health and social progress. Nanomaterials, with their unique nanoscale properties, offer innovative solutions for noise control by enhancing the acoustic efficiency of sound-absorbing materials. This review highlights the integration of advanced nanomaterials, including carbon nanotubes (CNTs), graphene, nano-silica, and emerging alternatives such as nanofibers and hollow silica structures, into composite systems, and indicates that enhanced acoustic performance is most often achieved through appropriate nanofiller selection combined with tailored pore architecture and composite design. These materials exhibit exceptional improvements in Sound Absorption Coefficient (SAC), Noise Reduction Coefficient (NRC), and Sound Transmission Loss (STL). Factors influencing acoustic performance, such as material composition, structural properties, and environmental conditions, are explored alongside advancements in characterization techniques. By examining current trends and innovations, this paper underscores the transformative potential of nanomaterials in designing lightweight, durable, and efficient acoustic solutions for diverse industrial and environmental applications.
