DESIGN AND IMPLEMENTATION OF A FIXED SYSTEM FOR VIDEO-ACOUSTIC MONITORING OF URBAN NOISE POLLUTION

摘要

The intensification of transport in the urban environment has generated an increase of level noise. Therefore, the EC has implemented an environmental policy for the reducing the noise level. Thus, the limit values acceptable for the noise levels in urban areas are 50 dB. To determine the noise level for these environments were designed and made various systems to measure level of noise, the majority of them being portable. S.C. Aerostar S.A. in collaboration with the "VasileAlecsandri" University of Bacau has designed and developed a system for acoustic-video monitoring. It consists of two components: system fixed of video-acoustic monitoring located in different areas of the city; the dispatcher that retrieves and processes obtained data for making noise maps and generate alarm reports. In addition to other noise monitoring components systems, the proposed system also has a surveillance room with auto positioning software that aims to identify the source of noise pollution.
