Abstract: The technology disclosed relates to systems, methods, and devices for non-destructive evaluation (NDE) of a wooden specimen. A computer-implemented method for non-destructive evaluation of a wooden specimen comprises receiving acoustic wave signal data from NDE of the wooden specimen; processing the acoustic wave signal data to determine signal characteristics, such as an arrival velocity and amplitude attenuation of an AW2 mode; determining, based in part on a characteristic of the AW2 wave, an estimated strength metric of the wooden specimen; and displaying, on a graphical user interface associated with the computing device, an indication of the estimated strength metric of the wooden specimen.
