AE Generation from Radial and Tangential Sections
of Softwood during Drying

In order to examine the generation mechanism of acoustic emission, AE, during wood drying, AE event counts were measured during drying of radial and tangential sections with different thicknesses and lengths from hinoki, Chamaecyparis obtusa. Relations of  AE total event count to thickness and length of a section strongly suggest that the withdrawal of water from ray parenchyma cells is responsible to AE generation from sections.
