A number of cases have been presented in the past, where "reverse engineering" was applied to improve the quality of emission data of roads so urces in city wide noise models with help of measurements. In a road network it will typically be easier to create a one to one relation between sources and measurement positions than in industrial compounds. In such cases ISO suggests estimating average emission levels of the industrial area based on a number of peripheral measurements. This approach has limitations where the property is of a complex shape, placed within a built up area or where it is difficult to define a representative height of the substituting area source. The technique of "reverse engineering" is less restricted in the choice of measurement positions or shape of the industrial area under investigation. Background sources and unknown sources at different heights, screening and reflecting objects may be integrated into the model. The paper will describe the practical experience of an environmental impact analysis for an industrial plant and compare the influence of source emission definition in line with ISO to the approach of "reverse engineering". This will touch economic as well as accuracy aspects. |
