The Role of IoT based on LoRa Technology in Urban Noise Management Noise pollution is a long-term problem for urban residents. Recent studies have estimated that nine out of ten people in large cities are exposed to an environment where noise levels exceed international standards. The negative effects of noise on health include sleep disturbances, hearing loss, cognitive impairment, and high blood pressure. Recently, Jinan City has set up a low-cost acoustic sensor network to continuously monitor noise in urban environments. They use LoRa technology, which uses a massive LoRa module and a small number of gateways and repeaters to build a system to implement optical inspection at a very low cost.
