Abstract
A system for detecting wood-destroying insects by sensing acoustic emissions generated by the insects as they feed. The system comprises two acoustic emission sensors, an amplification section, a signal processing section and an indicator section. The system comes into mechanical contact with the wood to be inspected through the use of a bolt which is inserted into the wood and attaches to an acoustic emission sensor or through the use of an adhesive layer which directly attaches an acoustic emission sensor to the wood. The acoustic emission sensors are electrically connected to the amplification section which is electrically connected to the signal processing section. The signal processing section is capable of distinguishing between insect-caused acoustic emissions and noise-caused acoustic emissions detected by the acoustic emission sensors. The results of the signal processing section are sent to the indicator section.
