## 1 Introduction  
The materials used in civil structures play a key role in shaping the physical integrity of buildings and their acoustic performance. This review focuses on sustainable materials such as wood composites, natural fibers, and recycled agricultural byproducts due to their dual functionality of providing the necessary structural support and enhancing the sound absorption and insulation properties. Using these materials helps meet the growing demand for sustainable construction methods. In particular, wood composites have exceptional acoustic properties, making them suitable for reducing noise pollution in urban environments and improving acoustic comfort in classrooms and offices. One of the main problems with traditional materials used for structural purposes, such as concrete and steel, is their significant environmental impact, including high carbon emissions associated with production and a reliance on non-renewable resources. Additionally, these materials often exhibit acoustic performance limitations, leading to noise control challenges within built environments. In contrast, this review paper highlights how innovative wood composites and bio-based materials offer enhanced sustainability through renewable resources and improved acoustic properties, addressing the dual challenges of environmental responsibility and noise reduction in structural applications. The research methodology for this review paper comprises a structured approach to assess the advancements in wood composites and their acoustic performance. A comprehensive literature review is conducted to gather existing studies on integrating wood composites with advanced manufacturing techniques, focusing on their acoustic properties and the identification of parameters influencing sound absorption and insulation. The bibliography findings are synthesized into thematic categories, such as using different sustainable materials and manufacturing approaches. The review also includes a comparative analysis of experimental results from various studies, highlighting the performance of wood composites in acoustic applications. In addition to the review, gaps in the current literature are identified, suggesting areas for future research. This dual approach will aim to bridge theoretical insights with practical implications, providing a holistic view of the potential for wood composites in sustainable acoustic material applications. The development of sustainable and high-performance acoustic materials is a key focus in contemporary research. Wood composites, such as those incorporating wood particles, fibers, or chips, have demonstrated significant promise in enhancing acoustic performance in green dividing panels [1]. Additive manufacturing, particularly 3D printing, has revolutionized the design of complex acoustic structures, including those based on wood composites. For instance, biodegradable panels made from polylactic acid (PLA) and wood particles have achieved high sound absorption coefficients, showcasing the potential of wood-based composites in sustainable acoustic applications [2]. Additionally, 3D-printed honeycomb structures filled with wood-derived nanofillers have shown potential for lightweight applications in industries such as defense and aviation [3]. Studies have also highlighted the influence of manufacturing parameters, such as the nozzle diameter and internal configurations, on the acoustic performance of 3D-printed wood composite panels [4]. The integration of wood composites with other sustainable materials, such as expanded polystyrene (EPS) or natural fibers like kenaf and jute, has further expanded their acoustic potential [5; 6]. Research into lightweight concrete panels incorporating wood-based recycled aggregates has addressed the long-term sustainability of noise barriers, while structural pervious concrete with wood composites has been developed to balance acoustic absorption, structural strength, and porosity [7; 8].
