Techno-Economical Study of Innovative Construction Material for Industrial Noise Abatement

Now a days Noise pollution is largest unwanted sound in the industrial sector. The Global population has grown in different decades Such as 1980-2000, 2000-2024. The annual population increase during the preceding decade about 2 percent. Due to increase in population, urbanization and industrialization happening and because of this noise pollution is increasing. In the world mostly noise generated from industrial sector. This noise create negative impact on surrounding environment such as (human, vegetation and animals) health. Effect of exposure to high noise level on workers and their performance of work and calmness. This research work was conducted to investigate the use of sound absorbing various combinations of green material for industrial noise attenuation to give effective solution for industrial noise problem. The specimen was prepared using different combinations with binding material cement (Adhesive). Noise reduction coefficients of specimens were calculated by using impedance tube system experimental setup. Effectiveness of sound absorbing natural materials for industrial noise attenuation is discussed in this paper.
