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 treatments for noise sources such as industrial equipment, transportation facilities, and construction sites, such as installing mufflers and soundproofing covers; designing soundproofing and absorbent materials for noise transmission routes, like setting up acoustic barriers and soundproof walls; and implementing protective measures in sensitive noise areas such as residential areas and schools, such as installing soundproof windows and planting soundproofing green belts. Additionally, it also encompasses noise monitoring and evaluation, as well as the establishment and enforcement of noise standards.
