Sound Propagation Through a Forest: A Predictive Model

Abstract

Previous attempts at modeling sound propagation through a forest have largely neglected the effects of a sound speed profile. This paper presents a PE-based sound propagation model that includes forest effects. In addition to a simplified but realistic sound speed profile, the model includes ground impedance effects, bulk attenuation due to multiple scattering by tree trunks and canopy, and the usual spherical spreading and atmospheric absorption.
