Abstract: Recent research and development on acoustic technologies has brought the operational assessment of acoustic speed as a measure of stiffness into forest management and log and lumber processing sectors of the industry. Significant values are associated with stiffness in log supply for LVL veneer production as well as structural lumber manufacture. Measurement of acoustic speed allows this value to be captured through better decision-making, allocation of resource to highest value users, and application of best processing methods dependent upon log-by-log measures. This paper reviews recent experience with field application of acoustic technologies to measure the stiffness of logs and trees during harvesting and logmaking operations and discusses research challenges which have arisen. It presents results from in-forest and resulting in-mill log-by-log acoustic measurement and associated values.
