Noise mapping based on participative measurements

Abstract

International audienceThe high temporal and spatial granularities recommended by the European regulation for the purpose of environmental noise mapping leads to consider new alternatives to simulations for reaching such information. While more and more European cities deploy urban environmental observatories, the ceaseless rising number of citizens equipped with both a geographical positioning system and environmental sensors through their smartphones legitimates the design of outsourced systems that promote citizen participatory sensing. In this context, the OnoM@p system aims at offering a framework for capitalizing on crowd noise data recorded by inexperienced individuals by means of an especially designed mobile phone application. The system fully rests upon open source tools and interoperability standards defined by the Open Geospatial Consortium. Moreover, the implementation of the Spatial Data Infrastructure principle enables to break up as services the various business modules for acquiring, analysing and mapping sound levels. The proposed architecture rests on outsourced processes able to filter outlier sensors and untrustworthy data, to cross- reference geolocalised noise measurements with both geographical and statistical data in order to provide higherlevel indicators, and to map the collected and processed data based on web services

Soundscape mapping in environmental noise management and urban planning: case studies in two UK cities

“…Some studies have tried to formulate a better traffic model by using dynamic noise mapping techniques [4,5] or even data extracted from participatory noise mapping techniques [6,7]. Moreover, the need to combine a holistic approach in environmental noise policy -by combining the noise mapping with the soundscape approach -has recently been raised by the European Environmental Agency (EEA) in the Good Practice Guide on Quiet Areas [8].…”

Findings from measurements of noise levels in indoor and outdoor environments in an expanding urban area: a case of Tirana

“…Similarly, much can be done on inhabitant participatory on measuring noise levels [7] in restaurants [45,46], food courts [47] to increase population and businesses awareness. This could help business reduce noise levels in their environments.…”

Special Issue on Environmental noise aspects in EU funded projects

“…Gwenaël Guillaume, Arnaud Can, Gwendall Petit, Nicolas Fortin, Sylvain Palominos, Benoit Gauvreau, Erwan Bocher and Judicaël Picaut in "Noise mapping based on participative measurements" [10] proposed the OnoM@p system as tool for obtaining by non-experts updated crowd noise data for noise mapping. The presented method consists in using opportunely equipped smartphones as both geographical positioning system and environmental sensors.…”
