DYNAMAP – Development of low cost sensors networks for real time noise mapping

Abstract

Abstract:The Environmental Noise Directive (END) requires that regular updating of noise maps is implemented every five years to check and report about the changes occurred during the reference period. The updating process is usually achieved using a standardized approach, consisting in collating and processing information through acoustic models to produce the updated maps. This procedure is time consuming and costly, and has a significant impact on the budget of the authorities responsible for providing the maps. Furthermore, END requires that simplified and easy-to-read noise maps are made available to inform the public about noise levels and actions to be undertaken by local and central authorities to reduce noise impacts. To make the updating of noise maps easier and more cost effective, there is a need for integrated systems that incorporate real-time measurement and processing to assess the acoustic impact of noise sources. To that end, a dedicated project, named DYNAMAP (DYNamic Acoustic MAPping), has been proposed and co-financed in the framework of the LIFE 2013 program, with the aim to develop a dynamic noise mapping system able to detect and represent in real time the acoustic impact of road infrastructures. In this paper, after a comprehensive description of the project idea, objectives and expected results, the most important steps to achieve the ultimate goal are described.

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

“…7,14,16]. A common framework (CNOSSOS-EU) has been developed for member states of European Union [11], to assess noise in urban areas.…”

“…Besides noise level prediction, effects of traffic composition are studied on road noise [15]. Noise mapping system is developed to detect and show in real time the sound impact caused by roads [16]. Annual equivalent noise level under traffic urban condition is estimated using sampling as an technique for its estimation [17].…”

Detecting Anomalous Noise Events on Low-Capacity Acoustic Sensor in Dynamic Road Traffic Noise Mapping

“…Recently, the DYNAMAP project aims at developing a dynamic noise mapping system to represent the acoustic impact of the road traffic noise in real time in two Italian pilot areas, Rome and Milan [8]. The WASN envisioned for the DYNAMAP project is hybrid, composed of both low-cost high-capacity sensors and low-cost low-computation capacity sensors, as in RUMEUR network [5].…”
