Design and manufacturing of eco-friendly acoustic panels

Noise pollution poses a significant global challenge, prompting a surge in research aimed at addressing this issue. While traditional acoustic panels using synthetic materials are commonly advocated, concerns over their health and environmental impacts have sparked interest in sustainable alternatives. This paper explores the blossoming trend of utilizing waste materials, particularly natural cellulose fibers derived from agricultural byproducts like coir fiber and rice husk, for sound absorption. Embracing the axioms of sustainability, the study investigates the feasibility of replacing synthetic materials with natural fibers to reduce noise reverberations. Natural fibers such as coir, and rice husk or jute offer promising recyclable and biodegradable choices. The present research has achieved the outcomes of "Sustainable Serenity," a project focused on redefining acoustics with aesthetically pleasing, eco-friendly panels. Comprehensive testing demonstrates a reduction in echo by 39% which tends to diminish the corresponding value of 3.2% of conventional gypsum boards. The thermal resistance yielded 82oC again surpassing the value of 68.7oC for the conventional panels. Also, the impact strength, water absorption, and carbon footprint of the casted panels compared to traditional panels were evaluated to be applauding. The research highlights the potential of sustainable acoustic panels as a cost-effective, environmentally responsible solution for noise control. The aesthetically appealing design and superior performance of the casted panels with felt coverings underscore their suitability for promoting sustainability while enhancing acoustic environments.
