Acoustic tools such as the Director HM200 are able to sort lobs and boards according, to their intrinsic stiffness. Here, some uses of such tools are demonstrated. First, six logs are analyzed before sawing into cants and inndividual boards. Second, the same approach is reconsidered from basic principles, emphasizing the variety of investigative projects to match the species-specific responses to acoustics and the need to match local resources to local markets. fit both instances, correlations between acoustic properties measured in logs are related to those from cants, and boards. The offsetting effects, of changes in stiffness and density ill determining acoustic velocity discussed. The intention is to emphasize future possibilities for commercial application.
