Feller-Buncher Sounds with DBH

We were interested in predicting tree properties, particularly size, from the sound made by a feller-buncher hotsaw during felling. Included are 279 3-second clips of felling sounds, along with stem size (DBH) information. Cut duration was found to predict stem size moderately well (standard error of prediction = 4.6 cm), but not well enough to be useful in measuring properties of individual stems. Could be useful for tract-level, or per-hectare predictions.
