Abstract: A noise map facilitates monitoring of environmental noise pollution in urban areas. It can raise citizen awareness of noise pollution levels and aid in the development of mitigation strategies to cope with the adverse effects. However state-of-the-art techniques for rendering noise maps in urban areas are expensive and rarely updated (months or even years) as they rely on population and traffic models rather than on real data. Participatory urban sensing can be leveraged to create an open and inexpensive platform for rendering up-to-date noise maps. In this talk we present the design implementation and performance evaluation of an end-to-end participatory urban noise mapping system called Ear-Phone. Ear-Phone for the first time leverages Compressive Sensing to address the fundamental problem of recovering the noise map from incomplete and random samples obtained by crowdsourcing data collection. Ear-Phone implemented on Nokia N95 and HP iPAQ mobile devices also addresses the challenge of collecting accurate noise pollution readings at a mobile device. Extensive simulations and outdoor experiments demonstrate that Ear-Phone is a feasible platform to assess noise pollution incurring reasonable system resource consumption at mobile devices and providing high reconstruction accuracy of the noise map.
