Wireless Acoustic Low-cost Sensor Network for Urban Noise Monitoring

Résumé

The concept of Smart Cities and Internet of things for monitoring of environmental parameters is trendy area of research that has attracted scientific attention during the last decade. Amongst the several pollutant that have to be faced on a daily basis, the noise pollution is one of the most widely known emerging and challenging problem in all large metropolitan areas, affecting the health of citizens in multiple ways. Recent technologies of low- cost and low-power devices allowed researchers to develop monitoring devices for deploying Wireless Sensor Networks (WSN) with a higher granularity than the traditional handheld analyzers, allowing massive noise monitoring. This paper presents prototyping of a low-cost acoustic sensor based on the STM32 platform for noise monitoring and analysis. The accuracy of the sensor is configured by comparing the results with professional handheld analyzer through calibration test. The acoustic sensor developed in this paper aims to be an appropriate replacement for traditional handheld SPL devices in that it possesses the same output of the sound pressure level and is also provides a continuous and autonomous data acquisition. Through this deployment it was demonstrated that the overall trends in urban noise can be observed and better understood with higher granularity network that allows continuous measurements, thus allowing gathering information that could help the citizens and the urban planners to improve city designs in order to accommodate the rapid urban growth and sustain the overall quality of life.
