Abstract
A self vibration of piezoelectric ceramics caused by a power supply through a feedback system was observed during AE measurements. Significantly different results from previous reports were obtained by eliminating the self vibration of the ceramics. The AE generation in PZT was mostly caused by 180° domain reorientation
