Meteorological effects on long-range propagation : Evaluation of the long-term sound level using statistical analysis.

Résumé

The influence of temperature and wind gradients on long-range sound propagation has been known for years. However, today it is very difficult to estimate a reliable long-term sound level value from one level measured over a period smaller than one year. The first part of this paper presents the method used to obtain a series over several years of theoretical hourly sound attenuations between a point source and a receiver. Typical results given by a statistical analysis of this series are also presented. The second part presents an application of this method for estimating the long-term sound level value from one level measured over a short period.
