  • Implementing noise prediction standards in software

    Software requirements in the 80's Until the 80's most consultancy projects were based on noise measurements due to complaints. As noise legislation became more strict, noise prediction became more important. New national and international noise prediction standards As there was no commercial software available many consultants started to develop their ...

  • Sensitivity analysis of simulation model on railway rolling noise prediction

    The railway rolling noise prediction software (RRNPS) is a simulation model for predicting the sound pressure levels during a train passage due to wheel/rail roughness, based on vibration dynamics, contact mechanics and sound radiation modules. Some field validation has been done under European and Australian conditions. Comparisons between simulations and measurements have shown that this ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Noise Planning Software Used to Map Major EU Roadways

    Most countries have a national noise policy to protect citizens from undesirable environmental noise levels from road, rail and air traffic and industrial sources. The European Noise Directive for the Assessment and Management of Environmental Noise outlines a coordinated method to achieve noise reduction in large cities as a first step, followed by smaller cities as a second step. The ...

  • 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 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 ...

  • Procedures to analyse noise maps in connection with noise action plans

    After finishing of the noise mapping of the European Noise Directive1” the noise action planning follows. This part of the END-projects concerns with measures for noise reduction in general and in detail and information and collaboration of the public. In this process a huge amount of measures and alternatives accumulates. Therefore automatic working tools for evaluation of the measures and ...

  • Queensland Rail – An example in effective noise mapping and noise control implementation for existing rail operations

    There is an increasing trend in the world today to model noise impacts of city-wide infrastructure such as rail, road and industrial activities.  This is particularly true of the European Union, which sought to produce an integrated approach across member states to predict city-wide long term average noise levels. The outcome of such an exercise usually results in production of 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. ...

  • Software implementation of the harmonoise/imagine method, the various sources of uncertainty

    ABSTRACT Uncertainty in noise prediction is usually thou ght of being related to the accuracy of the  input data and the accuracy of the prediction method. However documentation of the  prediction standard that contains ambiguous algorithms and unclear definitions of  geometrical calculation data will also lead to uncertainty in software implementation. The  past ...
