Towards an extensive noise and air quality measurement network

Abstract:

This paper presents ongoing research of the IDEA (Intelligent, Distributed, Environmental assessment) project. The aim is to build an extensive multi-sensor urban measurement network. The focus is on noise and air pollution caused by road traffic. The use of cheap sensors is an important prerequisite to come to implementation of such a network. The potentially lower data quality resulting from the use of cheaper sensors should then be overcome by adding intelligence to the network at various levels. A flexible network architecture was designed for the specific aims of the IDEA project. Two noise-related aspects are dealt with in more detail in this paper. Firstly, results from indoor and outdoor testing of different types of microphones are shown. Secondly, the estimation of pollutant concentrations based on noise measurements is proposed to help interpolating expensive-tomeasure air pollutants.
