Two important terms in forestry are the Quality (Grade) and Soundness (Scale) of the log. The quality of a log expresses the exact grade of the log and whether the defects (if any exist) are detrimental to the final product's appearance. The soundness of the log signifies volume of usable wood. Reduced soundness is often associated with the presence of rot. Wood is sound only if there are not present any rot pockets, holes, or knots that have to be removed (although other defects may be present). In other words, sound wood is equivalent to a nearly flawless solid content. The state of soundness may affect the quality of a wood product.
