Abstract
Wood, like many heterogeneous materials, provides many interesting AE challenges. It is a biological material that has evolved to perform many functions. It is anisotropic, and it is heterogeneous over a very wide range of length scales. It is hydroscopic, and its mechanical properties are extremely sensitive to moisture content. From an AE standpoint it is an extremely dynamic material in that there are numerous microstructural phenomena that lead to AE activity, however, it is highly attenuative, particularly in a direction perpendicular to the grain.
