SOUND PROPAGATION AND ATTENUATION CHARACTERISTICS OVER A HEAVILY VEGETATED TERRAIN

Abstract

The object of the study was to establish methods for predicting sound propagation losses over areas covered with thick vegetation or forest. In dealing with problems in this regime, the concept of layered media boundary condition is of prime importance. The study is being conducted through both analytical and experimental approaches.
