Detection of Termite Attack Using AE Sensor with Waveguide

-Application of Needle-type Waveguide-

For measurement of AEs generated by termite attack in the studs of the wall panel, the AE sensor was attached using the needle-type sensor holder as a waveguide. It plays a role of a waveguide penetrating through the wall covering made of plaster board and wall paper, that it is difficult to propagate AE waves.
