Influence of Impedance Properties of the earth’s Surface on Sound Attenuation During Near-Ground Propagation

We consider questions of the propagation of sound waves above the Earth’s surface. Formulas are given for the calculation of sound attenuation caused by the presence of the underlying surface. Different models of the impedance of the underlying surface are presented. Results of theoretical calculati...

Description
Summary:We consider questions of the propagation of sound waves above the Earth’s surface. Formulas are given for the calculation of sound attenuation caused by the presence of the underlying surface. Different models of the impedance of the underlying surface are presented. Results of theoretical calculations of the attenuation of sound as it propagates above various types of underlying surfaces are presented. The influence of the geometry of the propagation of sound on its characteristics is analyzed.
