Abstract
The comfort level of human being can be increased by effective noise management without damaging the external environmental resources. The burning of rice stubble particularly in rice growing Asian countries makes the situation bad to worst. Rice stubble deserve for an immediate solution of in product development for its sustainable disposal. Rice stubble, cotton fly waste were used to manufacture composite material to be used as acoustic panel. Rice stubble powder 60%, 70%, and 80%, cotton fly waste 20%, 30%, and 40% by weight, and polyurethane (PU) resin were used to manufacture composite as acoustic panels. The composites were tested for pore size, morphology, water absorbability, and noise reduction coefficient (NRC) mainly. Acceptable level of NRC and other features were achieved. This study will provide a new pathway to use the discarded challenging waste materials to manufacture wealth-generating products.
