Computer-implemented processing of sound wave signals for non-destructive evaluation of wooden specimen

A computing device comprising:

• one or more computer-readable storage media;
• one or more processors operatively coupled with the one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media that, when executed by the one or more processors, direct the computing device to at least:
• receive, by a first acoustic wave transducer, first acoustic wave signal data transmitted by a second acoustic wave transducer for non-destructive evaluation (NDE) of a wooden specimen, wherein the first acoustic wave transducer and the second acoustic wave transducer are operatively coupled to the computing device;
• receive, by the second acoustic wave transducer, second acoustic wave signal data transmitted by the first acoustic wave transducer, wherein the second acoustic wave signal data is transmitted simultaneously with the first acoustic wave signal data;
• process at least the first acoustic wave signal data to determine wave characteristics;
• determine an estimated strength metric of the wooden specimen based on one or more of the wave characteristics;
• and
• display, on a graphical user interface in communication with the computing device, an indication of the estimated strength metric of the wooden specimen.

One or more non-transitory computer-readable storage media having program instructions stored thereon that, when executed by one or more processors operatively coupled with the one or more non-transitory computer-readable storage media, direct a computing apparatus to at least:

• receive, by a first acoustic wave transducer, acoustic wave signal data transmitted by a second acoustic wave transducer for non-destructive evaluation (NDE) of a wooden specimen, wherein the first acoustic wave transducer and the second acoustic wave transducer are operatively coupled to the computing apparatus;
• process the acoustic wave signal data to determine wave characteristics, wherein to process the acoustic wave signal data, the program instructions direct the computing apparatus to identify an AW2 wave based on detecting a peak energy of the acoustic wave signal data;
• determine an estimated strength metric of the wooden specimen based on one or more of the wave characteristics;
• and
• display, on a graphical user interface in communication with the computing apparatus, an indication of the estimated strength metric of the wooden specimen.
