"最近，深夜没有听到商场噪声，终于能睡个踏实觉了！"在福建福州市仓山区，红星国际晶品小区居民 林强满意地说。 噪声污染是环境领域集中投诉的热点之一。自2021年起，福建省生态环境厅会同公安、住建、交通、市 场监管等部门，联合开展"静夜守护"专项行动，重点整治建筑施工、社会生活、交通运输等方面的夜间 噪声扰民问题。经过持续治理，各渠道噪声投诉量较整治前下降约30%，监管机制初步实现常态长效。 福建龙岩市武平县城市管理和综合执法局人员深入调研，精准定位了28处广场舞热门场地。不罚款、不 驱赶，城管队员先和领舞的阿姨大叔们聊家常，记录活动时间、人数，科学规划"健身课表"；然后告知 管理规章，活动限于早上6点半至晚上9点，保证活动不扰民；最后递上《广场舞温馨公约》：60分贝 是"白天快乐线"、50分贝是"夜晚温柔线"——这个标准成了武平广场舞参与者的一致共识。 噪声具有瞬时性，导致执法人员难以及时固定证据，不可避免面临"取证难"。为破解这一问题，福建编 制《重点领域环境噪声自动监测管理工作指南》，目前已初步建成噪声监测网络。全省布设工业企业、 建筑工地、道路交通噪声监测点位各10318个、2018个、570个；住建、 ...

Core Viewpoint - The sound barrier industry in China is experiencing significant growth driven by urbanization, increased demand in transportation and construction sectors, and heightened public awareness of environmental issues. The production and demand for sound barriers are expected to rise steadily, with market size projected to reach 115.36 billion yuan by 2025 [1][5]. Industry Definition and Classification - Sound barriers are measures used to block direct sound between a source and a receiving point. They can be classified based on usage (traffic, equipment noise reduction, industrial), material (metal, concrete, PC, fiberglass), and purpose (railway, highway, urban landscape, residential noise reduction) [2][3]. Industry Development Status - The development of sound barriers in China began in the 1970s. The industry faces challenges due to high customization requirements and varying specifications. The production is expected to grow from 4,828 million square meters in 2024 to 5,358 million square meters in 2025, with demand following a similar upward trend [3][5]. Market Size and Growth - The market size for sound barriers in China is projected to reach 105.23 billion yuan in 2024, with significant contributions from the transportation sector (75.4 billion yuan) and industrial production (16.48 billion yuan). By 2025, the market size is expected to grow to 115.36 billion yuan [5][18]. Industry Chain - The sound barrier industry chain includes upstream raw material supply (metal materials, PC boards, glass), midstream product manufacturing, and downstream application in construction, industrial production, and urban transportation. The collaboration across these segments is crucial for industry growth [7][18]. Competitive Landscape - The sound barrier market in China is characterized by a large number of manufacturers with relatively weak overall strength. Key players include state-owned enterprises, private companies, and foreign firms, with notable participants such as Hengxiang Technology, Tibet Zhongchi Group, and Changzhou Tiansheng New Materials [9][12]. Key Companies - **Tiansheng New Materials**: Focuses on high polymer material processing, with significant patents in sound barrier products. The company reported a revenue of 531.2 million yuan in 2024 [12][13]. - **Hengxiang Technology**: Provides integrated solutions for traffic noise control and has a diverse product range including sound barriers and engineering rubber products [15][18]. Industry Development Trends - The sound barrier industry is expected to benefit from China's stable economic growth, accelerated urbanization, and advancements in technology and materials. Environmental sustainability will also play a crucial role in shaping the market [18][20].
