DESCRIPTION:Salil Kanhere\nAbstract: A noise map facilitates monitoring of
  environmental noise pollution in urban areas. It can raise citizen awaren
 ess of noise pollution levels  and aid in the development of mitigation st
 rategies to cope with the adverse effects. However  state-of-the-art techn
 iques for rendering noise maps in urban areas are expensive and rarely upd
 ated (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 ma
 ps. In this talk  we present the design  implementation and performance ev
 aluation 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 incomple
 te 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 devi
 ce. Extensive simulations and outdoor experiments demonstrate that Ear-Pho
 ne is a feasible platform to assess noise pollution  incurring reasonable 
 system resource consumption at mobile devices and providing high reconstru
 ction accuracy of the noise map.
