The harmonoise sound propagation model further developments and comparison with other models
conference paper
The Harmonoise sound propagation model ('the Hannonoise engineering model') [1] was developed in the European project Hannonoise (2001-2004) for road and rail trafTic
noise. Further developrnents of the model were performed in the European project Imagine (2004-2006), including extensions of the model to aircraft noise and industrial noise.
In 2008, CSTB Grenoble and TNO Delft have prepared a detailed description of the various steps involved in a calculation with the Harmonoise model. In the course of this
joint project, solne elements of the model were further improved. In 2009, test calculation were performed with the model, and results were cornpared to results of other models,
both accurate reference models and the Scandinavian Nord2000 model [2,3].
In this article we present results of the comparisons. First we give a brief overview of the Harmonoise model, including salient features such as the convex hull approach, Fresnel
weighting for irregular terrain, and ground curvature to account for the effect of a atmospheric refraction
noise. Further developrnents of the model were performed in the European project Imagine (2004-2006), including extensions of the model to aircraft noise and industrial noise.
