  • Urban Noise Monitoring in Madrid

    Dynamic mapping helps Madrid improve the quality of life for her citizens and visitors alike. With its 3 000 000 inhabitants and 2500 km of streets, Madrid is an excellent example of what can be done to improve human comfort related to urban noise. Since the late 60s, Madrid City Council has been working on noise problems. During this period, global environmental analysis has focused on how ...

  • Noise in Europe 2014

    Noise pollution is a growing environmental concern. It is caused by a varied number of sources and is widely present not only in the busiest urban environments, it is also pervading once natural environments. The adverse effects can be found in the well-being of exposed human populations, in the health and distribution of wildlife on the land and in the sea, in the abilities of our children to ...

  • Noise Mapping in Lille

    Lille, with a population of 1091 million inhabitants is the 4th largest agglomeration in France after Paris, Lyon, and Marseille. Situated at the heart of a network of 464 km motorways connecting six European cities (Brussels, Bonn, the Hague, London, Luxembourg and Paris), the metropolis of Lille also has the densest railway network of France after Paris. Pascal Thomas and his team of 8 ...

  • Traffic Noise Mapping in Chile

    Against this backdrop of economic change, a two-year study got underway across three Chilean cities led by the Univ. Austral. and was supported by the Chilean Ministry of the Environment. Academically titled: “Development and analysis of noise maps of three urban agglomerations using modeling software”, the study concentrated on the Chilean cities of Coquimbo – La ...

  • Road traffic noise in downtown area of Tehran

    Noise pollution is by now worldwide recognized as a major problem for the quality of life in urban areas. Vehicular traffic is the most important source of the environmental noise pollution in these areas (Zennin et at., 2001; Suksaard et at., 1999; Arana and Garcia. 1 998. The increasing in the population and in the number of circulating vehicles has led to an increase in the noise pollution but ...

  • Accurate and efficient prediction of acoustical performance of noise barriers against transport noise pollution

    An improved acoustical wave propagator (I_AWP) technique with high-order absorbing boundary technique is introduced to evaluate the acoustical wave interaction for noise barriers, providing the dual benefit of preserving high numerical accuracy (boundary conditions have been properly treated) and obtaining high computational efficiency (using a larger time step in the calculation). The aim is to ...

  • New techniques to determine specific noise for increasing the effectiveness of continuous unattended noise monitoring systems

    Continuous, unattended noise monitoring systems can immediately alert you should noise levels exceed defined criteria. Once alerted to an exceedance, operators can act to return levels to compliance. This approach has two significant limitations. Firstly the operator can only take action after the breach has occurred and therefore systems are only able to inform owners about problems that have ...

  • Redesigning urban transport

    The world’s cities are facing unprecedented problems. In Mexico City, Tehran, Kolkata, Bangkok, Shanghai, and hundreds of other cities, the air is no longer safe to breathe. Respiratory illnesses are rampant. In the United States, the number of hours commuters spend sitting frustrated in traffic-congested streets and highways climbs higher each year. In response, forward-thinking city planners ...

  • How big should urban green spaces be?

    With cities poised to add 2.5 billion more people by 2050, now is a perfect time to get strategic about urban design. One of the big questions planners face is the best way to accommodate both built environments and natural settings, which provide important services such as making oxygen, cleansing water, absorbing noise, ...

  • Creating an entire country`s noise map - Case Study

    To comply with the European Union’s Environmental Noise Directive 2002/49/EC, member states are required to create updated noise maps for large urban areas and major transportation sources every five years. The English government commissioned a single project to calculate sound levels across the whole of England which resulted in the world's biggest noise map. ...

  • Mitigation measures to minimise traffic–generated noise pollution in Metropolitan Kuwait

    Forty representative roadway locations were randomly selected for monitoring traffic flow and noise levels. At local streets, equivalent noise level (Leq) ranged between 56 to 71; at collector streets traffic areas 70 to 83; at arterial roadway 75 to 86 and at freeway roadway areas 75 to 88 dBA during day and night time respectively. Consequently, the level of noise pollution from traffic even at ...

  • Subjective evaluation of urban environment: a case study in Beijing

    There is a growing interest in Chinese citizens' attitudes towards economic reform and development, but little attention has been paid to their views on the urban environment. Based on the results of our recent survey in Beijing, this paper discusses the public awareness of the current urban natural and social environment, of the relationship between economic development and environment ...

  • Assessment of noise level due to vehicular traffic at Warangal city, India

    In the light of the rapid growth of vehicles and the ill effects due to noise pollution, there is a need to study noise pollution from the transportation point of view. In this study, an attempt has been made to study noise pollution due to vehicular traffic in Warangal city, India. It was observed that noise levels are increasing with increased traffic volume. Studies also revealed that ...

  • Univariate stochastic model for predicting carbon monoxide on an urban roadway

    This paper describes the development of the univariate time-series models for forecasting 1-h average carbon monoxide (CO) concentrations during the critical (winter) period. The CO data covering the period from 1st November to 31st December 1999, has been used for the development of Box?Jenkins models at two Air Quality Control Regions (AQCRs) – traffic intersection (AQCR1) and an arterial road ...

  • Urban environment — SOER 2010 thematic assessment

    Urban areas and quality of life For the three-quarters of Europe’s population that lives in cities and towns, a good urban environment is a precondition for a good quality of life. It seems, in part, that over the last decade, attitudes to living in cities have been changing. People are no longer moving away from cities (or have returned to them), residential sprawl has slowed and, in a ...
