Core Viewpoint - The new Noise Pollution Prevention Law in China, effective from June 5, 2022, establishes legal standards for noise pollution, emphasizing proactive control measures rather than just compliance with decibel limits. This shift is expected to drive the noise control industry towards more efficient and sustainable practices, with a projected market size of approximately 24.734 billion yuan in 2024, reflecting a year-on-year growth of 7.79% [1][4]. Industry Overview - Noise control, also known as noise pollution management, aims to reduce noise levels to meet national standards and protect individuals' quality of life. The law defines noise pollution as sounds that disrupt normal activities, covering industrial, construction, transportation, and social life sectors [2][3]. Industry Development History - The Chinese noise control industry has evolved over 70 years, transitioning from basic regulations to advanced smart management. Key milestones include the introduction of the first industrial noise prevention guidelines in 1956 and the establishment of a comprehensive legal framework by 1996. The current phase emphasizes intelligent monitoring and proactive measures [3][4]. Market Size - The noise control industry in China is projected to reach approximately 24.734 billion yuan in 2024, with a growth rate of 7.79%. The shift in regulatory focus from compliance to proactive prevention is expected to enhance market dynamics [1][8]. Key Enterprises - The market is characterized by low concentration, with companies leveraging technological advantages to dominate specific segments. For instance, Beijing Jiuzhou Yigui leads in rail transit noise reduction with patented technologies, while Guangzhou Sound Doctor has established a brand in building sound insulation [8][9]. Industry Development Trends 1. **Shift from Passive to Active Control**: The industry is moving towards proactive noise management, particularly in industrial sectors, driven by legal requirements for noise pollution control [12][13]. 2. **Technological Advancements**: Future competition will focus on precision and intelligence in noise control, utilizing IoT and AI for real-time monitoring and assessment of noise impact beyond just decibel levels [13][14]. 3. **Comprehensive Management Systems**: The industry is evolving towards a holistic management approach that includes planning, regulation, and community involvement in noise control efforts [14][15].
