Cross-University Team Develops Mobile 'Ears' for Real-Time Environmental Noise Monitoring

A research team from National Yang Ming Chiao Tung University (NYCU), Academia Sinica, and National Tsing Hua University (NTHU) has developed a low-cost, high-sensitivity noise sensing module. Acting like 'mobile ears' for the city, these devices can monitor environmental noise in real-time, aiding in precise environmental management. Unlike traditional, expensive monitoring equipment with limited placement, these sensors cost about NT$1,000 each and can be powered by portable power banks, allowing for large-scale deployment in streets, communities, and campuses. Data collected is analyzed via Chunghwa Telecom's cloud resources using AI models to generate visual noise heat maps. The team has conducted field tests in New Taipei and Taoyuan, showing accuracy comparable to standard methods used by the Ministry of Environment.
