Sound propagation in the rest atmosphere with linear sound velocity profile

Sound propagation is considered in the rest atmosphere where the sound velocity varies linearly with height. With the results of the ray theory of refraction being introduced to the asymptotic solution of spherical wave propagating over a locally reacting ground surface, the approximated solution of...

Summary:Sound propagation is considered in the rest atmosphere where the sound velocity varies linearly with height. With the results of the ray theory of refraction being introduced to the asymptotic solution of spherical wave propagating over a locally reacting ground surface, the approximated solution of the sound field is obtained. The results of calculation by this theory explains the measurements satisfactorily, as a result quantitative prediction of excess attenuation is available.
