Industrial growth in India generates major noise pollution which becomes a serious environmental issue. An excessive noise level in the industries can contribute to poor occupational health such as noiseinduced hearing loss; decrease the performance of workers and affecting productivity. To enhance workplace environment there is a need to find out harmless and effective noise control methods. the research work is carried out to explore the use of natural materials (agricultural wastes) for noise reduction for industrial structure. For specimens mold was used having 75 mm diameter and 25 mm high. These molds were cast using materials viz; Hyacinth, Maize, and coconut coir dust.

Keywords : Hyacinth, Noise Reduction Coefficient, Impedance Tube.
