Internet of Things for Noise Mapping in Smart Cities: State-of-the-Art and Future Directions

Abstract：Noise pollution has been an issue since ancient times. Recently, this problem has been exacerbat-ed due to rapid population growth and urbaniza-tion. Noise mapping is a strategic action plan that visualizes the long-term and real-time noise pollu-tion of our cities, industrial sites, and other regions of interest. This article first discusses the working principle of general model-based noise mapping and the lessons learned. Then, in-depth descrip-tions of the technical challenges and design issues of noise mapping using mobile crowdsensing and acoustic sensor networks are presented. Finally, we provide our insights for future research direc-tions regarding artificial intelligence assisted noise prediction, constructive interference for multime-dia transmission, and simultaneous noise sensing and sound energy harvesting as well as inaudible sound attacks and defense.
