Noise control engineering is a comprehensive field, primarily including three major aspects: identification and control of noise sources, blocking of noise transmission pathways, and protection of noise reception points. Specific tasks involve noise reduction for sources such as industrial equipment, transportation facilities, and construction projects, like installing mufflers and soundproofing covers; soundproofing and absorbent design for noise pathways, such as setting up acoustic barriers and soundproof walls; and protective measures in sensitive noise areas, like residential and school zones, such as installing soundproof windows and planting soundproofing green belts. Additionally, it encompasses noise monitoring and evaluation, as well as the establishment and enforcement of noise standards.
