Abstract

In the case of medium and long ranges outdoor sound propagation, refraction due to temperature and wind gradients may increase (or decrease) the sound pressure due to a point source. To fulfill the needs of practical outdoor sound propagation studies, it appears to be necessary to predict the sound speed profile (SSP) according to general meteorological informations. The paper describes a practical method to estimate the sound speed profiles (SSP) under general meteorological conditions. The paper presents a method to estimate the corresponding linear SSP that can be incorporated in the heuristic acoustical model for outdoor sound propagation. Finally, the paper gives comparisons between experimental and theoretical results
