Coupling Meteorology to Acoustics in Forests
Abstract
The U.S. Army has a growing interest in the use of advanced sensors and computer models to retrieve. display and interpret acoustic signals from sound-emitting targets in and around forests. Outdoor sound speed is an essential parameter for determining point-to-point acoustic propagation. The speed of sound is often expressed as a function of air temperature, humidity, and wind velocity. Therefore, we have reviewed selected past research on micrometeorology within and above forests to examine the calculation of the speed of sound through the atmosphere in the forest environment for military acoustic applications. Our objective is to evaluate meteorological models for estimating wind speed and temperature profiles within and above forests to determine those most applicable in representing mechanical and thermodynamic influences on the speed of sound in the forest environment.
