Acoustic Tree Tomograph: ArborSonic 3D | Fakopp

Our most sought-after product among arborists is designed to detect the size and location of decayed or hollow regions within tree trunks. It operates with impressive speed, allowing a measurement to be completed in just 5-10 minutes, and generates a comprehensive 3D model of the trunk with multiple layers of measurement. Additionally, the software offers customizable wind load modeling. What sets it apart is its non-destructive technique that employs sound waves, avoiding any use of radiation. For trees with thick bark, we also provide 12 cm long nails as an option.



Use a rubber hammer to drive the transducers evenly through the bark, maintaining consistent spacing around the trunk. Measure the distances between the transducers with a caliper, recording the data on the computer. Generate sound waves by tapping each transducer with a steel hammer; ArborSonic 3D precisely measures travel times to each transducer, transmitting the data to the computer. The software then calculates and displays the internal sound-velocity distribution of the tree. These measurements, gathered at different heights, can be compiled to create a comprehensive 3D model.
