Core Viewpoint - Noise pollution prevention is a significant issue affecting people's livelihoods, and the development of noise mapping technology is expected to provide effective solutions for managing noise pollution [1][2]. Group 1: Current Situation of Noise Pollution - The newly revised Noise Pollution Prevention Law and the "14th Five-Year" Action Plan lay a legal foundation for noise pollution control, but challenges remain in achieving the goal of "quiet cities" [2]. - Noise pollution has become increasingly prominent, especially in densely populated urban areas, with a reported 5.706 million noise complaints in 2023, an increase of 1.203 million from the previous year [2]. - Noise complaints accounted for 61.3% of all ecological environment complaints, making it the most significant environmental issue reported [2]. Group 2: Challenges in Noise Pollution Management - Monitoring and assessment of noise pollution are difficult due to its transient and mobile nature, leading to low coverage and poor timeliness in monitoring [3]. - The sources of noise pollution are diverse, including industrial, traffic, construction, and social activities, complicating regulatory efforts [3]. - Public awareness regarding noise pollution is low, with many individuals unaware of their noise contributions and lacking motivation to report issues [3]. Group 3: Application of Noise Mapping Technology - Noise mapping utilizes geographic information systems to visualize noise levels and distributions, aiding in identifying major sources of noise pollution [4]. - In Suzhou, Jiangsu Province, noise mapping has been implemented to create a comprehensive noise monitoring network, enabling minute-level tracking of noise pollution [4]. - The establishment of a sound fingerprint database has facilitated efficient inter-departmental collaboration in noise regulation [4]. Group 4: Promoting a Collaborative Noise Management Framework - A noise map application for residents allows the public to view noise distributions and report issues, transforming them from bystanders to active participants in noise management [5]. - The "14th Five-Year" Action Plan encourages cities to leverage noise mapping and information technology for precise noise pollution control [6]. Group 5: Recommendations for Noise Mapping Implementation - The promotion of noise mapping should be tailored to local needs, focusing on areas with significant noise issues [7]. - Expanding the application of noise maps in urban planning can help preemptively assess noise impacts before approving new developments [7]. - Financial support and incentives should be provided to local governments and businesses that actively engage in noise mapping initiatives [7]. - Investment in technological innovation is essential to develop cost-effective noise monitoring solutions suitable for smaller cities [7].

Core Viewpoint - Acoustic technology is becoming a new engine for technological innovation, with various acoustic smart terminals entering households and industries, enhancing control and understanding of sound [1][4].
