NOISE MAPPING OF LARGE REGIONS - EXTRA BENEFITS

摘要

Environmental noise analysis, especially when used for END noise mapping, will require large and detailed modelling data. Different sources of data provision are involved. Modelling data is not subject to any fixed scheme and thus after 10 years of END extra efforts are still needed to create a homogenous model. Available data get ever more detailed and unveil more data conflicts. In consequence the amount of necessary refinement seems to increase. In support of financial efficiency modelling and calculation shall aim at working on larger regions which produces new challenges in data storage. From the economic point of view one may consider using these models for noise abatement. As abatement considerations shall take air pollution aspects into account it is only logic that the same model shall be fit for air pollution calculation.
