ArborSonic 3D Acoustic Tomograph
ArborSonic3D is an acoustic tomograph used for non-destructive testing of trees, which can produce a map of internal velocities of a cross-section.
- Detects the size and location of decayed or hollow regions
- Measures sound travel time between sensors
- Determines velocities from the measured time and geometry
- The software calculates cross-sectional velocities
- Fast: a measurement can be completed in 5-10 minutes
- 3D model using multiple layers
- Wind load modeling including EN1991
Drive the sensors through the bark using a rubber hammer with even spacing around the trunk.
Measure the distances between the sensors with a caliper and enter the measured data to the computer.
Tap each sensor with a steel hammer to generate sound waves. ArborSonic 3D measures the travel times with microsecond precision to each sensor and transmits the data to the computer.
The software calculates and displays the internal sound-velocity distribution of the tree.
Measurements taken at various heights can be assembled into a 3D model.
