摘要：

Comparisons between acoustic emissions and piezoelectric properties in wood drying were performed. It was determined that with acoustic emission the signal resolution was better than with piezoelectric effect. Acoustic emissions were affected by drying gradient and wood species. in this case the frequency of acoustic emission was between 30 and 200 kHz. Acoustic signals can be used for the control of wood drying processes. For industrial use of these technology more investigations are to be worked out.
