Abstract
Environmental noise generated during chemical production not only severely affects the quality of life of surrounding residents but also poses potential threats to the health and safety of workers, thus necessitating the development of efficient and feasible noise control technologies. This study focuses on typical noise sources in chemical production, aiming to explore noise control methods suitable for complex industrial environments and proposes a comprehensive noise reduction strategy that combines active and passive approaches. By integrating field monitoring with laboratory simulations, the study systematically analyzes the primary noise spectral characteristics and propagation patterns of operating chemical equipment, while introducing novel sound-absorbing materials and intelligent control systems to enhance the effectiveness of traditional passive noise reduction techniques. Additionally, this research innovatively applies adaptive signal processing algorithms to the field of active noise control, significantly improving the attenuation capability for low-frequency noise. Experimental results demonstrate that the proposed integrated technical solution can reduce the sound pressure level of key noise sources by 10~15 dB(A), exhibiting excellent stability and economic viability in practical applications. The main contribution of this study lies in overcoming the limitations of single noise reduction technologies, providing new theoretical foundations and technical pathways for noise management in the chemical industry, and laying a groundwork for noise control research in other industrial sectors..
