Noise absorbing composite materials using agro waste products in construction: State of Art Review

The development and properties of a noise absorbing composite material using agro waste products for use in construction. The material was composed of a matrix of bio-based resins and agro waste fillers, including rice husk and sugarcane bagasse. The effects of filler content and resin type on the mechanical and acoustic properties of the material were studied using various testing methods. Results showed that the composite material had good sound absorption properties, with higher filler content resulting in better noise reduction coefficients. The use of agro waste products in the material also had environmental benefits and potential economic advantages. The findings of this study contribute to the development of sustainable building materials and provide insights for future research in this field.” Agro waste products are produced during the processing of agricultural products, and they include a wide range of materials such as straw, husk, bagasse, and sawdust. [21] These materials are abundant and can be used as a source of raw materials for the production of noise-absorbing composite materials. Research has shown that agro waste products can be used to produce composite materials with excellent acoustic properties.
