Sonic unit finds borers in piles
British Columbia Research Council (BCRC) is using sonic device to measure marine borer damage to underwater wood piles; test does not damage pile; it requires no core sampling of wood or even removal of barnacles or other fouling material; device pulses ultrasonic waves from transducer toward heart of pile; wood responds by emitting radial waves picked up by receiving transducer, converted into electrical signal, amplified and fed into calibrated oscilloscope; reading indicates condition of pile; compression tests performed by owners both on damaged and undamaged piles indicate accuracy of BCRC method.
