Abstract - Now-a-days sound pollution is a major issue. Urbanization, industry, transportation, and public gatherings all contribute to noise pollution, which can cause major health problems like stress, hearing loss, and lost productivity. Traditional sound-absorbing materials, such as fiberglass and polyurethane foam, work well but are bad for the environment since they don't biodegrade. Eco-friendly acoustic panels composed of natural waste peanut and coconut shells with a constant 40% binder are the subject of this investigation. Coconut shells improve mid-frequency absorption and provide mechanical strength, whereas peanut shells efficiently absorb high-frequency noises because they are lightweight and porous. Three mix configurations were examined, and each component offered unique acoustic benefits. According to Noise Reduction Coefficient (NRC) analysis, the best balance in acoustic performance was demonstrated by the ideal mixture of 30% peanut shells, 30% coconut shells, and 40% binder. Although their moisture sensitivity necessitates waterproofing measures, these panels are affordable, environmentally friendly, and appropriate for non-load-bearing acoustic applications like wall treatments. The results show that agro-waste has a strong future as a sustainable substitute for synthetic acoustic materials.
