Application and validation of a meteorological-acoustical model for outdoor sound propagation
conference paper
The Dutch project “Geluid in Beeld” (A view on sound), investigates the impact of industrial sound from the Europort/Maasvlakte area towards the city of Oostvoorne. The reason for this project are unexpected noise complaints, see 1. The project was initiated by The Port of Rotterdam, DCMR, EMO and ECT. This paper presents the comparison of the calculated sound propagation results with the results from a detailed measurement campaign in the area. Also, sound propagation results are compared to a number of periods where an increased number of complaints were reported. For the sound propagation, a detailed meteorological-acoustical model is applied. This model is used for distances typically between 1 and 10 km. Especially for areas with a combination of land and water, the vertical wind and temperature gradients can vary strongly along the propagation path. To describe the meteorological situation in detail a mesoscale meteorological model is used. Large scale weather data from HiRLAM is used as input. For the validation measurements, a set of 16 loudspeakers was used as a sound source. For two source positions and along three measurements lines, sound measurements were done in the afternoon, evening and night. Meteorological measurements at several heights were performed at two positions.
