The rise in pollution has prompted an increased demand for sustainable materials. In this review, we explore studies that investigate natural materials for acoustic absorption panels. This chronological literature review surveys studies that consider natural fibers for sound absorption, considering their technical feasibility by tabulating the Noise Reduction Coefficient. We collected and analyzed articles from Scopus, Engineering Village, Google Scholar, and ScienceDirect databases. For the selection of fibers, the following criteria were applied: the sound absorption coefficient must be obtained experimentally for greater accuracy, be single-layered, not present any added binder, have tables or graphs of the sound absorption coefficient by frequencies of at least 250–2000 Hz, and the difference in thickness between the thinnest and thickest layer tabulated should be a maximum of 0.05 m. NRC revealed low values for banana pseudostem (0.15), cotton (0.30), corn fiber (0.30), and cork (0.30). On the other hand, other fibers such as sheep wool (0.70), kenaf (0.70), coconut fiber (0.50), and betung bamboo (0.50) demonstrated exceptional results, confirming that natural fibers are viable options for sound absorption purposes.
