Evaluate Trees with Minimal Damage

ArborSonic 3D Acoustic Tomography by Wickes/ arborists is obviously the invasive evaluation tool for your trees. It works based on sound velocity measurement between several sensors around the trunk. "Because sound velocity drops in decayed areas, internal holes and decay may be detected and the risk of the tree may be better assessed," says Wickes/arborists owner, John Wickes. "It is a great way to evaluate trees because it does little harm to the tree. Like everything in life, trees need to be taken care of to maintain their longevity."

To perform 3D Acoustic Tomography, an arborist first drives the transducers through the bark using a rubber hammer with even spacing around the trunk. Second, the arborist measures the distances between the transducers with a caliper and enters the measured data to a computer. Third, the arborist taps each transducer with a steel hammer to generate sound waves. ArborSonic 3D Acoustic Tomography measures the travel times with microsecond precision to each transducer and transmits the data to the computer. The final step is that the software calculates and displays the internal soundvelocity distribution of the tree. "Depending on the result, the arborist will tell you what needs to be done in order for the long term care of your tree," says Wickes.
